Arm Coolers for Summer Cycling: A Look at Rapha and DeFeet

It is probably safe to say that most cyclists are not strangers to arm warmers. But what of their hot-weather cousins, the arm coolers? Those are a rarer beast. Worn with short sleeve jerseys, arm coolers are lightweight sleeves designed to protect from heat and sun. In intensely hot weather, wearing them is supposed to keep you cooler than cycling with bare arms or in a long sleeve jersey. So, do arm coolers work? Having tried the versions from DeFeet and Rapha, I believe they do. Here is more about them.










DeFeet ArmSkins ICE

Sun Protection: SPF 50

Fabric: olefin/nylon/spandex blend

Country of Manufacture: USA

Price: $45




The DeFeet ArmSkins Ice are designed for both sun protection and abrasion protection. They are made of a rather thick, densely woven fabric that evokes medical compression wear. The texture has a striking silky sheen to it when new, though it subdues after some use.






The ArmSkins Ice come in two sizes: S/M and L/XL. I fit the former. Pulling these on for the first time, the fabric is so dense it feels almost reluctant to stretch. But once in place, having these on is comfortable and non-constricting. For me the length is sufficient to overlap with cycling gloves.




The ArmSkins are constructed as seamless tubes. To stay up, they use a roll-top design instead of elastic or silicone grippers. The roll tops work fairly well to keep the sleeves in place, though on long rides I do adjust them occasionally. Personally I like the roll-top: Unlike silicone grippers - it does not pinch, squeeze or chafe the skin on my upper arms, especially on long rides in hot weather.






Developed for temperatures over 80F and well into the 100s, the fabric of the ArmSkins Ice is described as being activated by air-flow, the "densely packed fiber molecules" causing "rapid heat exchange. If I understand correctly, the claim is that the material does not just protect the skin from outside heat, but actually sucks and expels heat from the body. According to DeFeet, the dense weave also offers abrasion protection in case of a fall or scrape - more so than a leather jacket. A technical discussion in this review describes how all of this works in greater detail.




In use, the ArmSkins Ice feel cool to the touch, even in intense heat and sunshine. But moreover, once in a while I get the sensation of cold flashes along my arms. This happens in the absence of any breeze, but it does happen more when I ride fast, which probably means it is caused by increased air flow. To feel a chill on my arms in 90F heat and direct sun is quite something. I cannot comment on the abrasion protection, but the cooling properties of this garment are impressive. Wearing the DeFeet ArmSkins Ice feels like having an air conditioning system wrapped around my arms.






Rapha Arm Screens

Sun Protection: SPF 50

Fabric: polyester/elastane blend

Country of Manufacture: Turkey

Price: $45




The Rapha Arm Screens are made of a stocking-thin fabric. They weigh next to nothing and, crumpled-up, will easily fit into the meagerest of jersey pockets. Pulling them on, the material hardly registers between the fingertips.






The Arm Screens are shaped, with bonded seams running along the inside of the arm and articulated elbows. Reflective logos sit just above the wrists.




The sizing (XS-L) is similar to Rapha's arm warmers - which is to say, they run small. However, they are also very stretchy, so there is some leeway. I am a US woman's size 4 with arms of average thickness and below-average muscle tone. I can fit into the Small, but the Medium feels more comfortable - with no sausaging effects and with length to spare. For those unsure about their size, I would suggest erring on the larger side: The longer length will ensure there is no gap between the Screens and your cycling gloves.






The Screens stay up with the help of elasticised bands, which are as thin as the rest of the fabric. There is no silicone gripper and, compared to other designs, the hold is gentle - not pinching or squeezing the skin at the top. But the bands have worked well for me so far. For example, they kept the Arm Screens in place for over 15 hours straight on a recent long ride. The fabric feels delicate, though after some weeks of rough handling I have not snagged it yet.




The "proprietary stretch Swiss fabric" used to make these is a polyester/elastane blend with "coldblack technology to keep the fabric cool against the skin." It has also been subjected to "anti-microbial/anti-bacterial treatment." Beyond this, Rapha does not elaborate. But whatever the technology is, it works. Wearing the Arm Screens pretty much feels like not wearing anything at all. I do not notice them on, other than that my arms feel cooler. Compared to riding bare-armed, I do not feel the heat or the burn of the sun's rays against my skin. Perspiration does not gather on any parts of my arms and removing these after a long ride, they are dry. The Rapha Arm Screens protect from sun and heat, while feeling weightless and comfortable on all-day rides.






Identical in price point and SPF rating, the arm coolers from DeFeet and Rapha offer different technologies to deal with intense summer weather. A benefit specific to the DeFeet ArmSkins ICE is their added abrasion protection. A benefit specific to the Rapha Arm Screens is their weightlessness. Perhaps an obvious caveat - but both tend to get dirty in use, so do not expect them to remain bright-white for long.

The Russell Moccasin Co. and minimalist running shoes?

The Munson Army Last has been around since 1912. -Named after its inventor, Edward Luman Munson, A.M., -M.D., Lt. Col. Medial Corps, United States Army, the Munson Army Last was adopted by the U.S. Army to enhance the fit and comfort of military boots issued to soldiers. The Munson Army Last was and is one of the few lasts that ever approached normal feet shape and contour.





It was the view and understanding of Dr. Munson, way back then, that “Weakening of the foot muscles is one of the penalties of civilization, as walking is less and less a factor in locomotion....the introduction of railroads, street cars and automobiles, has materially interfered with foot development.”



http://www.russellmoccasin.com/munson_last.html











"I did an hour hike up and down a back-country ski trail the other day in a custom pair of minimalist shoes. Packed snow, nine degrees Fahrenheit, and my feet were toasty the whole way. They have no heel lift, no cushioning, an anatomically correct design, and are the only shoes I've found other than FiveFingers where I can actually splay my toes; they have excellent traction. No need for snow shoes, or Yaktrax.





A new start-up minimalist shoe company? Nope, this company has been making minimalist footwear for over 100 years. It's the Russell Moccasin Co. of Berlin, Wisconsin, and the shoe in question was produced for me as a prototype after a conversation with the 80-year old owner.



Like many of us, after starting to wear Vibrams on a regular basis, I realized that traditional shoes were no longer going to cut it. I'd been able to find decent, but not great, alternatives for office wear, but the one problem remaining was cold weather. How to get a boot that would be suitable for hiking in the winter in snow and on ice? After a good deal of research, I found that the Russell Moccasin Co. makes custom boots, and some of them sounded close to what I was looking for."

I suspect a few are now beginning to think I have lost my mind :)



I and my family have a long history with the Russel Moccasin Co. So if you have ever wondered where my shoe fetish started, it was here while in the 2nd grade.



I could go on but I'll leave that for the Q&A session in the comments that are sure to follow. If you are a minimalist runner I suspect you'll like what Russel has been doing with shoes and boots for years. For the rest of your it might take a bit of wrangling to wrap your head around the need let alone the actual shoes/boots Russel offersand their cost.



There isn't much footwear that gives Dane "happy feet". A custom pair of Russels is one of my definitions of the term. But until just the last few days I had never thought about actually just running in them. I have used them for everything else and in conditions that would never makes sense if you didn't know more about the construction of Russel's entire line of footwear.



But "just running" in them makes a lot of sense if you are into a minimalist running shoe. Which Ihave been, long before the Nike Free or Vibram 5 Finger.







If you ever wondered what tight rock shoes or rigid soled mountaineering boots were doing to your feet this is a good read. Dr. Edward Luman Munson's observations from 100 years ago:http://www.archive.org/details/soldiersfootmili00munsrich

Velosteel Coaster Brake Hub

When I decided to build up an ANT Truss Bike as a single speed with a coaster brake, I soon discovered that the only commonly available hub choice was Shimano. I have ridden Shimano coaster brake hubs, and there is nothing wrong with them. But somehow having one on a bike that was otherwise so old-school and classic felt off. So I asked around and learned, via the ever-helpful bikeforums, about a small manufacturer in the Czech Republic called Velosteel.






Velosteel focuses exclusively on producing single speed coasterbrake hubs. As I understand it, they took over the machinery that was used by the former Fichtel & Sachs company to manufacture the original Sachs hubs before SRAM bought them out. Therefore, Velosteel hubs are supposed to be identical to the vintage Sachs single speed coaster brake hubs found on many continental European city bikes made prior to the year 2000 - especially Dutch and German bikes. I have ridden a number of bikes with Sachs hubs in the past and I've always liked them, which made Velosteel an appealing choice.




As of last summer, the way to buy a Velosteel hub was on ebay. I do not remember where I bought mine, but I am told this is a reliable source in the US. I am still not aware of any US bike shops that carry these hubs, but if you are please let me know and I will update this information. I bought the hub, and Jim at Harris Cyclery built me a wheel around it.






While I am not sufficiently knowledgeable to explain why the Velosteel hub is more "old school" in its construction than a currently-produced Shimano hub, suffice to say that its overall form, its finishing, and the way the shell is put together all look distinctly different from modern hubs and distinctly similar to vintage ones.




There is no branding on the hub itself, and the only mark of the manufacturer seems to be on the reaction arm, which is stamped with: "VELOSTEEL MADE IN CZECH REPUBLIC." There may be a serial number stamped somewhere indicating date of manufacture and such, but I have not noticed it.






Having ridden the ANT over the past several months, I can make some observations about the Velosteel hub. My first impression was that it was too "soft;" I could not lock up the rear wheel without exerting a huge amount of effort. However, I wanted to wait before sharing this impression - thinking that it was possible the hub would "wear in" over time. And it did, after about 40 miles - during which I made it a point to use the brake often. Now the hub can lock up the rear wheel with reasonable effort. It also modulates braking power very nicely, which is something I love about a good coaster brake.I do feel that the Velosteel allows for finer modulation than the currently produced Shimano coaster brake hub.I get into the rhythm of using it, and it makes city cycling feel like such an organic, smooth experience.




Last year I started a discussion about vintage vs modern coaster brakes and the amount of backpedaling "give" they allow before the braking mechanism is engaged. I noted that in my experience, older coaster brakes allow for more give, which I prefer. In the comments others reported this difference as well - but some suggested that it might be a function of the vintage coaster brakes being worn out with age, as opposed to differently designed. Well. My Velosteel hub started out brand new, and it has "give" similar to the old vintage Sachs coaster brakes I've ridden. This is just one piece of anecdotal evidence of course, but I think it's useful to offer it.






Overall I like the Velosteel hub and have a feeling it will only improve with age - somehow, I feel as if it's still wearing in. I would love to get feedback from others who have used it, especially on a bike that's their regular commuter and for a period of several years.




As with everything, I think it is good to have options. The Velosteel hub might be a welcome alternative to Shimano for those who prefer a coaster brake hub with a more classic look and feel. I wish more American bike shops carried Velosteel.

Woodchucks at Grand Portage State Park

At work this week we've noticed some new little critters running around near the visitor center... a family of woodchucks! They are living under the boardwalk and in the bushes next to the visitor center. Throughout the day they venture out to chew on the grasses and dandelions in the yard.



Every now and then one of the young ones takes off running down the paved trail, much to the delight of the park visitors. They look so funny when they are running full speed! And, they are much quicker than I thought. I never realized they could run so fast.



We have recently had construction work begin on the site for our new visitor center, so there is a lot more noise than there usually would be, what with chainsaws running and dump trucks and loaders coming and going. The noise doesn't seem to bother these guys, though, as they are pretty active all day long. If you happen to visit the park, keep an eye out for them as you walk past the visitor center!

Off to these countries!

Bags have been packed and all ready to go!



As a tradition in this blog, I always post the picture of the flag of the country that I am going to visit, and in this case, flags of the countries. So here they are ladies and gents:







United Arab Emirates (Dubai night and a whole day layover)







Singapore (2 trips)







Philippines (Cebu)







Hong Kong SAR







Macau SAR







Malaysia (Malacca, Kuala Lumpur, Cameron Highlands)



I mentioned this trip earlier. Read here: Smorgasbord of upcoming trips to the Middle and Far East



Naturally I will continue to blog if there is internet, so do follow me. See you at the other side of the world! Tot zo!

Big Bend :: Castolon

Back in the early 1900s, the Castolon area was under cultivation. It was interesting to look at the area now and imagine green, luscious fields filling the valley, made possible through irrigation by pulling water away from the Rio Grande. Where now you see cactus, mesquite and other desert plants there were acres of cotton, sorghum, alfalfa, corn, wheat, and melons. Actually, it is beyond imagining. It really is hard to believe that someone could actually farm in that rocky, sandy soil.

The remains of several houses of the farming families are still standing and can be seen on a short half-file walk about seven miles from the campground. One such farmhouse is that of James and Melissa Belle Sublett, settlers who came to Castolon in 1913. According to a sign at the site, James is recognized for introducing mechanized farming into Big Bend and also installed the area's first irrigation system supplied by a water wheel. By 1918, he owned nearly 3,000 acres of land in the area.

Built on the side of a hill, the walls of the Sublett home are all that remain. The back wall had no windows since it faced the hillside.

The remaining walls of the Sublett home.

The view from the front of the Sublett home. As beautiful as it can be sometimes, I'm not sure it would be worth it to me to live in such a place. For some it obviously is, but I'm not one of them!

The Dorgan House, shown below, was built in the 1930s by Albert W. Dorgan and his wife Avis Ann. The adobe home had large windows at the front and a double fireplace that opened into the central living area. In 1938 the Dorgans vacated this property and in 1941 leased it to A. F. Robinson who opened a resort hoping to benefit from the new Big Bend National Park. The resort was a failure and the Dorgans sold it for inclusion in the park.

In the early years of the park, historic structures like the Dorgan and Sublett homes, were either destroyed or allowed to deteriorate because they were not thought of as part of the natural scenery.

The Dorgan house was built on a mesa, which overlooked the Sublett home.

The fireplace in the Dorgan home, made of stone, petrified wood, and adobe bricks, dwarfs the remains of the house. It stands about 10 feet tall.

A detail of the adobe walls of the remains of the Dorgan home.

The ruins of the Sublett home, in the center of the picture, appears insignificant in context of its surroundings. The mountains behind the home are in Mexican territory. The Rio Grande flows at the base of those mountains, several miles from the Sublett home.

The Subletts and Dorgans would have witnessed many such mornings as this. In their struggles to make a living, I wonder if they saw the beauty around them.

Dutch Bike: Impressions After an Absence

I own a 15 year old Gazelle A-Touren that is pretty much the prototypical Dutch bike. It was my main city bike for a while, until I put it in storage last November. Yesterday I retrieved the Gazelle (I am looking to sell itedited to add: I have now sold this bicycle), dusted it off, and rode it for the first time in 4 months. The nice thing about riding a very distinct type of bicycle after a long absence, is that everything about it seems new again and you notice aspects of the ride quality that didn't stand out when the bike was familiar. So I wanted to take this opportunity to write up my impressions of Dutch bike handling - from the altered perspective of someone who's now also ridden a variety of other bicycles.





My first impression of the Gazelle upon our reunion had to do with the riding position. I forgot that it was even possible to be sitting that upright on a bicycle! I consider my other 3-speed and my mixte to be upright bikes as well, but they are certainly not compared to the Gazelle. The rider's position on this bike is akin to sitting in a chair: back straight, shoulders relaxed, hands holding the bars in much the same manner as one would hold an open newspaper or a tray.







The handlebars are dramatically swept back and very close to the body. There is no feeling of reaching at all - my hands just basically rest on the bars naturally if I simply plop them down, bent at the elbows. This also means that there is very little weight being placed on the handlebars, or on the front end of the bike at all for that matter.





The unweighted front end was a sensation that took getting used to after an absence. However, it was really just a matter of training my body to adjust to it. After circling the block a few times and picking up speed, the handling already began to feel intuitive again. With the handlebars way behind the font hub, this is not a super-responsive bicycle. There is almost a feeling of passivity or detachment in riding it, like being in the back seat of a vehicle instead of the driver's seat.






These factors combined are what's responsible for the "regal" feeling associated with riding a Dutch bike. The effortlessness, the perfect posture, the ability to observe one's surroundings in a way that cannot be done on other bikes - it all encourages a relaxed and confident attitude. The wide 28" tires create a plush ride quality that further contributes to the luxurious feel. The nuisance of potholes and rough road surfaces need not trouble the rider. As I rode the Gazelle around the neighborhood, it felt as if I were sailing aboard a luxury liner more than riding a bike. I had completely forgotten that sensation.




Of course another thing I'd forgotten was the weight of the bike. At just under 50lb, the Gazelle is an armful to drag up and down even a small set of stairs on a regular basis. Having now gotten used to my "heavy" city bikes being a good 15-20lb lighter, I admit I did not welcome the extra weight.






The bike's weight however, does not pose a problem when the Gazelle is in motion. It accelerates easily and retains momentum extremely well. On flats I can fairly quickly get it to 17mph+ in the high gear, which is about as fast as I'd want to go in the city anyhow.




Uphill is of course a different story, though it's not quite as bad as you might think just by looking at the bike. Uphill the Gazelle is slow, but responsive to hard pedaling effort. Unlike some other heavy city bikes, it does not attempt to pull me back, but is willing to advance slowly forward and upward as long as I am willing to push.






Having had the bike out of sight for so long, it was also nice to see its lovely little details again. Being of mid-90s production, the bike is not exactly "vintage," but still the details were more nuanced on these older models than they are today. Examining all the intricate, albeit now rusty, little embellishments on it is a pleasure. The bike was well used before I got my hands on it, and spent a great portion of its life outdoors as I understand it. In light of that history, the extent to which its functionality and aesthetics have been preserved is impressive.






While I love and respect the Gazelle, for my current transportation needs I've come to prefer a more active ride and a slightly more aggressive posture. Still, the positive qualities of this bicycle are hard to beat.




The Dutch bike is an excellent choice for a cyclist who wants to be as upright and relaxed as possible, enjoys a plush ride, prefers to do little to no maintenance on their bicycle even in winter, lives in a fairly flat environment, and is undaunted by weight. It will also appeal to those who love vintage elegance: The basic design of the Dutch bike has gone largely unchanged over the past century and remains an icon of transportation cycling.
