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).

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).

  1. I have 700×35 New Xpress on my Saga, they measure at least 1 mm bigger on
    DT TK7.1 rims than Pasala 700×35 TG on CR-18 The New Xpress Somas seem to ride a bit nicer

  2. I followed a link here that suggested that the Soma Xpress tires did in fact have a dynamo strip. Is this a detail you know to be true? I was unable to get Marathons through the dealer I use, and have these tires ordered. I am looking forward to them, but I have a drum dyno, and am hoping they will work.

    1. The tires that I reviewed (which I’m still happily riding) have the standard Pasela tread/rubber, so there’s no dynamo strip.

  3. I have had the Soma Express (folding bead) on my commuter (H+ Sons archetype rims) for 6 months, about 1400 miles. They ride smoothly over the choppy pavement, grip well in the wet, and have very good roll for a 35×700. The rear showed some reasonable wear after 1200 miles – fine crosshatching mostly gone. I run them at 80PSI and the ride is very comfortable, directionally stable, and confident in the corners. The only negative I have is that they flat more than most tires I have run – Gatorskins, Bontrager Race Lites, and Panaracer Gravel Kings. That could be me, my roads, or just good old standard deviation. I got them for $16 each on a close-out sale, so I can’t really complain. Even at full price, they are a good value.
