Things I Like: DeFeet UnD Shurt Base Layer

I am not what you would call a fair-weather rider.  Whether it’s below freezing or when the mercury hits the triple digits, I love riding my bicycle.  And whatever the weather, DeFeet’s UnD Shurt base layer has been my go-to gear for remaining dry and comfortable.

Weighing only a few ounces, the UnD Shurt takes up very little room under form-fitting jerseys or other clothing.  The athletic cut is slim, but-comfortable, and there’s no annoying bunching or “riding up.”  And despite being whispery-thin, it’s not fragile, nor does it require special care.  One of my tank-style base layers has seen near-daily use for over a year, and is still going strong.

DeFeet recommends the UnD Shurt for 40° to 80° weather, and I’d say that their ratings are a little conservative.  While it may not offer as much warmth as the company’s UnD Wool model, it does an excellent job of keeping you dry when you’re layered-up for winter conditions (which there are no shortage of here in Colorado).  As someone who tends to sweat profusely, I’ve found that the UnD Shurt is ideal for staying dry and comfortable.

First Impressions: BikeHubStore.com Hubset

Over the last two-and-a-half years, BikeHubStore.com of Chapel Hill, NC, has made a name for itself by offering great deals on hubs, rims, and spokes.  For the past couple of months, GRAVELBIKE has been testing two of the company’s latest offerings–the SL218 rear hub, and the SLF85W front hub.

BikeHubStore.com’s SL218 and SLF85W hubs.

Both hubs feature CNC-machined 6061 alloy bodies, 7075 alloy axles, and roll on Enduro sealed bearings (which are easily serviced with common hex keys).  Our samples came in a 28/32 configuration with a Campagnolo-compatible freehub (130mm rear spacing).  Weight was dead-on at 85g (front) and 218g (rear).  For this review, the hubs were laced to H Plus Son Archetype rims by local expert Peter Chisolm of Vecchio’s Bicicletteria.  Sapim spokes completed the build, with 2.0/1.5/2.0 Lasers being laced 2x in front, and 2.0/1./8/2.0 Race laced 3x in back (both using brass nipples).

The heart of the SL218 rear hub is a six-pawl, alloy freehub.  The hub is available in Shimano- or Campagnolo-compatible versions, and both drivers are fitted with two Enduro sealed bearings.  Engagement is solid (even below freezing), and the axle’s drive-side end cap features an additional rubber seal that does an excellent job of keeping water and dirt away from the bearings.

The SL218′s freehub is well sealed and easy to service.

For this test, I used a Campagnolo Veloce cassette with separate cogs, and couldn’t detect any excessive gouging or notching of the freehub body’s splines.  One thing to note, however, is that the SL218′s freehub positions the largest cog very close to the spokes.  Extra care should be taken when adjusting the rear derailleur’s inner limit screw so that there’s no contact with the spokes when the chain is on the large cog.

One of the highest compliments I can bestow on the BikeHubStore.com hubs is that I basically forgot about them.  They worked (very) well, and didn’t require any babysitting or tweaking whatsoever during the test period.  Whether I was exploring dirt roads or riding pavement, they became “invisible” and let me focus my energy on enjoying the ride.  And in all honesty, you really can’t ask for more than that.

Under Test: Sugino OX601D Crankset

Sugino’s OX601D is the less expensive version of the company’s OX801D compact-plus crankset.  The combination 110mm/74mm BCD allows small rings as low as 24t and specially-matched big rings as large as 50t (or as small as 42t).  Q-factor is 145mm, and the ramped-and-pinned chainrings are compatible with 9/10s Shimano and 10s SRAM chains (and worked fine with my 10s Campagnolo drivetrain).

First Impressions: SOMA New Xpress Tires

In the world of bicycle tires, there is rarely such a thing as a “free lunch.”  Puncture resistance often comes at the expense of ride quality and light weight.  Faster-rolling tires usually don’t last as long, and can sometimes be more prone to flats or cuts.  For riders who want a blend of performance and durability and reliability, SOMA Fabrications offers the New Xpress tire.

Made in Japan by Panaracer, the New Xpress utilizes the same micro-tread as the company’s popular Pasela tire.  The New Xpress comes in steel- and folding-bead versions, and is available 26″, 650B, and 700C sizes.  The 700×32 (folding) samples that I received measured 30.5mm wide (mounted on 23mm rims) and weighed 420g each.  Suggested retail for the blackwall, folding-bead model is $44.99/each.

To help reduce punctures and cuts, New Xpress tires feature a HyperTex-reinforced casing.  SOMA claims that HyperTex is more flexible than Kevlar (for a smoother ride), but still strong enough to improve durability and reliability.  In my testing I found that the HyperTexvcasing felt stiffer than a plain skinwall, but didn’t have the harsh ride found on more heavily-armored tires.  I noticed that the reinforced casings enabled the use of lower pressures without resulting in a squirmy feel (which was especially welcome when riding off-road and in snow).

HyperTex layer runs bead-to-bead for added protection.

Over the past several weeks, I’ve ridden the SOMAs on pavement, dirt roads and trails, and yes, gravel.  Transitioning between the different surfaces proved to be no problem.  A few of those rides included snow and ice, and the tires performed surprisingly well–especially when I dropped the pressure to 40psi front and 50psi rear.  And while it’s hard to predict how long the tires will last, the high-carbon rubber shows very little wear thus far.

The New Xpress tires do a fine job of balancing performance and reliability.  I found the latter especially reassuring when commuting in sub-freezing temps before and after dark (but I would opt for the version with reflective sidewalls for increased visibility).
