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).

The new Pacenti SL23 rims arrived this week.  Weighing 450g, the 24mm-wide rims feature machined brake tracks (with wear indicators) and welded construction.  Our review samples were laced to White Industries T11 hubs by Ergott Wheels.  In between snow storms, I managed to snap a few pics of the complete wheels.  Stay tuned for a full review.

First Impressions: SeatSleev Retention System

In the days before saddle packs, riders used an old toe strap to secure their spare tubular to the saddle’s rails.  Then, as clinchers gained popularity, saddle packs became more ubiquitous.  When saddlebags became passe, tubes and mini-tools were then relegated to jersey pockets.  But now there’s another option for carrying spare kit–the SeatSleev retention system.

Conceptually, the SeatSleev is the exact opposite of a saddle pack.  All your gear is visible–and more importantly, accessible–even when strapped to the saddle’s rails.  With the SeatSleev, there’s no rummaging through packs or sagging jersey pockets.

OK, it’s convenient, but is it secure?  Absolutely.  I’ll admit that I was a little skeptical at first, but I’m pleased to report that the SeatSleev is very secure.  The heavy-gauge elastic conforms to the items’ individual shapes, and cinching down the dual hook-and-loop keeps everything in place (even on dirt roads and trails).

A compact and convenient alternative to traditional saddle packs.

Capacity-wise, I was able to able to carry everything that normally resides in my medium-sized Lezyne saddle pack (with room to spare).  And while I’m certainly no featherweight, the SeatSleev is about half the weight of the aforementioned saddlebag (45 grams vs 85 grams).

The SpeedSleev retails for $34.99, and can be purchased on the company’s website.

First Impressions: Schwalbe Marathon Winter Tires

Last February, I logged a measly 25 miles for the month because of icy roads.  This winter I vowed that Mother Nature would not get the best of me.  Ice or no ice, I was going to keep riding.  In order to meet that goal (and stay upright), I decided that it was time to invest in some studded tires.

Checking the internet, I discovered that Schwalbe offered four studded tires.  Since I would be riding primarily on pavement, I chose the Marathon Winter in the 700×35 size.  The studded Marathon utilizes the company’s RaceGuard anti-puncture technology, and is constructed from a special winter (rubber) compound.  The tires also feature reflective sidewalls, and dynamo strips.

One of the first things you notice about the Marathon Winters is their weight.  The 35mm versions weigh 910 grams–230% heavier than the Vittoria Voyager Hypers that I normally run.  At the maximum recommended 85psi, the tires measured 35.1mm when mounted on 23mm rims.  Before the carbide studs are broken in, they’re surprisingly sharp, so it’s not a bad idea to wear gloves when mounting these tires.

On dry pavement, the Schwalbes are extremely sure-footed thanks to the 240 carbide studs.  They’re also a bit noisy, but I found that I tuned it out after a short while.  Traction on dirt roads and trails was outstanding, even at pavement-friendly pressures.  My first encounter with ice was, thankfully, uneventful.  Straight-line traction (and braking) was very predictable, but I did detect some slipping when transitioning between the center and side studs (decreasing the pressure improved traction, however).

Surprisingly, snow presented more of a challenge than ice.  The Marathon Winters fared well in fresh snow (as long as it wasn’t too deep), but navigating rutted, “crusty” snow was tricky.  For those types of conditions, the wider 700×40 version would have been a better choice.

Because of the tires’ increased drag (and added weight), I only use them when I expect extended icy conditions.  After approximately 150 miles, the tread shows virtually no wear, and no studs have ripped out.  At this rate, I expect that the tires will last many years.
