About Soma Cycles:

Practical, durable, comfortable, affordable… these are the primary forces shaping Soma’s ideology. Sounds reasonable right? But why do so many other companies try to emulate the racing world when it’s the smallest segment of the market? Our local bike shops have felt a lack of ‘real’ products aimed at the everyday cyclist and occasionally pitch their ideas at us. The results: A better tire lever, water bottles that don’t taste like plastic, and steel frames that’s got people smiling from the commute to the singletrack. The San Francisco Bay Area is where we are located. We love the year round riding weather here and the strong bike culture. It’s a great place to live and cultivate new ideas.

The Wolverine:

The original inspiration for the Wolverine was “monster cross”, but it is seriously so much more. Its geometry is stable enough for off road touring, but sporty enough for all-around adventure and gravel riding. With its sliding dropouts, you can run single-speed, derailleur gearing or hub gearing.

The primary differences between the 3.0 and v. 4 Type-A and B is a new 46cm size, an extra set of water bottle bosses, and additional stack height on most sizes.

The Type-A ALSO adopts more modern standards such as 142mm rear thru-axle and a 44mm headtube that will fit 1-1/8 straight steerer or tapered steerer with the proper headset type.

There is NO frame break for Belt-Drive like the B-Type has. (See chart for other differences between A and B)

  • What Gates Belt-Drive Set Up is recommended?

    With an Alfine 8 spd hub, we recommend 46t front, 24t rear, and 115 length belt, with the dropout set at 440mm from the center of the BB axle. We recommend the Center-Track system. Shimano Alfine Di2 does not fit on the Wolverine because the narrow belt line needs of the hub.

    Wolverine 2.0, 2.1 , 3.0, and 4.0 B models approved for use with belt-drive with Rohloff hubs. With Rohloff for gravel, a 50t front x 19t rear x 115 belt and 440.19 chainstay setting is a good place to start. Use a smaller front ring for touring and trail riding.(https://www.cyclemonkey.com/blog/calculating-gear-ratios-rohloff-speedhub) You will need a Monkey Bone and OEM Plate #2 to make the set-up work.

    For Single Speed:

    46t front x 26t rear x115 belt – 435.19mm chainstay setting

    Please check out the Gate’s Drive calculator on their website. Plug in 430mm as a representative chainstay length. The recommended useable range on the Wolverine in 429-445mm. It will give you belt length when you type in the gearing you want.

WOLVERINE V.2.0/V.2.1

  • Bicycle Quarterly: Fun Versatile Bike

    Excerpt from the print magazine: …. The Soma Cazadero tires on our test bike cleared the chainstays with just enough clearance for a little mud. Soma reckons that 42mm tires will fit with fenders – and it seems plausible, since you can slide the rear wheel backward in the dropouts. But otherwise, the Wolverine covers all the bases: Disc brakes eliminate issues with brake judder (cantilever brakes) or excessive brake flex (long reach sidepulls). There are multiple rack eyelets. Downtube shifter bosses give you options of how to operate your derailleurs, while sliding dropouts allow running the bike with a single-speed drivetrain. ….The Wolverine [is] a fun bike. …the Wolverine tracked straight, handled predictably and faded into the background like a good bike should. On the truly muddy stuff, the Wolverine’s handling seemed a little less predictable than that of my Alan cyclocross bike – probably a function of the Wolverine having more trail and wheel flop, and thus less steering precision. It wasn’t a deal breaker, and even while powersliding the bike through muddy turns, not once did I have to unclip to restore my balance. If you are looking for only one bike to own, and don’t know yet how you’ll use it, the Wolverine is a great choice. It can take you on many adventures, whether it’s touring, gravel riding, cyclocross, or even a bit of road racing.

  • 6-Month Review of the Wolverine by Australia Mountain Bike Magazine

    “…Given my mountain biking background, I wanted to see how hard I could push the Wolverine. I raced several dirt crits aboard the Pumpkin Orange steed, which warranted some pretty strange looks on the start line. My first lap at race pace was quite the baptism of fire, with me rolling through transition looking like I’d been inside a washing machine. Once I started to pick the right race lines though, I loosened up and began to ride smoother. The rigid setup means the handling is very direct, with the short(ish) back end on the Wolverine helping to deliver pinpoint steering accuracy when exiting tricky corners. On tight switchbacks where some mountain bikes can feel a little vague, the Wolverine feels nimble and lively. It’s refreshing in a very honest kind of way…. Following the Wolverine’s dirt-crit flirt, I decided to spend some more saddle time exploring backcountry fire roads and double track in the local forests surrounding my hometown. On these slightly smoother surfaces, the Wolverine really comes into its own. It oozes comfort and stability, and it has no problems getting into a groove for all-day exploring. This kind of dirt-oriented adventure riding is where the Wolverine’s geometry really shines. With decent tyres and a comfortable cockpit setup, the Wolverine possesses a unique desire to maintain momentum on the kind of terrain that makes skinnier-tyre bikes feel uncomfortable, and fatter-tyre mountain bikes feel sluggish. The Skinny For me, riding the Wolverine has opened up a whole new riding experience. It’s an absolute hoot to ride off road because it really tests the limits of your fitness and skill. I have a number of local trails that can occasionally become a bit boring if I’ve over-ridden them. Not so on the Wolverine though, where all that old singletrack becomes new and exciting again. While it may be no frills compared to complex carbon full suspension bikes, the refreshing simplicity of the Wolverine is one of its greatest attributes. And it has to be said that for less than a grand, the Wolverine is superb value. It’s built from great quality steel tubing that is designed to last a lifetime, and it has all the necessary features that most riders are looking for these days. Once you factor in its versatility, the value is even more impressive. As a “Monster Cross” bike, the Wolverine definitely ticks a lot of boxes. It can handle loaded dirt touring, it’s functional enough for commuting, and it’s also a helluva lot of fun on the singletrack. Of course it is no expert at any of those riding genres, but the fact that it can do them all well is why I think Soma have built an absolute winner with the Wolverine.” Full review: http://ambmag.com.au/soma-wolverine-review/

  • SOMA(tic) Tangerine Wolverine

    Excerpt: read more at http://www.backalleybikerepair.com/somatic-tangerine-wolverine/ Built up, the Wolverine inspires confidence, begs to be ridden, and with the gentle slope of the top-tube it preserves an aesthetic that I find very important. I wanted to ride this bike all over the Cascades…The initial set-up of the bike was aimed at quick, spirited, 1-2 day summer adventures

    My very first impression was of how STABLE the front end feels. With a lightly loaded handlebar bag (I imported my usual set-up of a Nitto front rack and the Swift Industries small Ozette bag), the Wolverine’s slightly more raked out fork holds a line very well (as well as 650b??). Riding hands free is no problem, such as when grabbing for a snack, removing a riding layer, or taking pictures. Obviously 2.1-inch trail tires won’t feel spry climbing on Seattle’s hills, but they were fun! Especially cutting through alleys and around the Central District’s choppy streets and all over Beacon Hill. The Wolverine reminded me of when I switched from downhill skiing to snowboarding, and how I viewed terrain differently. Whereas obstacles and tree lines were only for flirting with on skis, on a snowboard I’d duck in and out of trees, I’d head straight for the swoopy humps and get some radness. Same thing with the Wolverine. I started popping off of dirt embankments, skidding into loose corners, and rolling obstacles like on-board a 29’er. The SRAM Rival shifting worked flawlessly, the wide gear range (50/34 and 11-32) was up for the aggressive riding as well as always finding a suitable climbing combination. Back on the street, I was reminded of girth of the tires, but smiling, scanning the urban landscape for the next adventure section of road/trail.

    During a wet ride, the front braking was a bit “pulsey”, requiring a bit more of a brake lever grab than I am accustomed to. This seems more a function of the TRP brakes and the brake pads needing to “settle” into the caliper. The handsome lugged front fork gave an accurate feel for whatever terrain I took it over. The 180mm rotor was a bit “grabby” on technical sections, tugging on the fork blades. The steering was even and predictable, albeit with a bit more rider input than I am used to with tighter geometry.

    There are only a few offerings in the “MonsterCross” catagory, but gravel grinders and bike-packers alike would respond well to SOMA’s newest family oddball. In the next couple of years, I expect this segment of the market to expand dramatically. SOMA has established the bar with a tremendously versatile steel bike. And what’s so odd about it? Well, just that there’s not much out there like it.

  • Soma Wolverine Review

    Within the whole of the bicycle industry I think we can all agree that bigger tires are better. All categories are running bigger tires; BMX, road, cyclocross, mountain bikes, tandems, recumbent, and even fat bikes. Soma, you have done a great job with this frame. The versatility to do whatever you want on this goes above and beyond. There are so many ways this could get built up and it all comes down to the users needs.

    First ride this weekend was about 2.5 hours long and who knows how many miles. No Garmins were used. Ever. I stand by that fairly firmly, unless I need direction in the back-country. Took a mixture of road and various park trails, access roads, and gravel paths. Got a little lost and had a great time.

    How is the bike? It is stable and smooth. At higher speeds, the stability is great. Not twitchy or a confidence killer. Disc brakes are awesome on all bikes. Less of a hassle, stronger braking, and they work great when wet and muddy. Makes riding with drop bars on rough trail a whole lot easier. Only set back was purchasing the TRP brakes. They are nice, yes. But the pads rattle a whole lot within the brake calipers. Gets a little annoying and makes you feel like something is falling apart. Only downside I have seen is not having through mounts for mid mounts on the fork. Limits the racks that you can put up front, but not a deal breaker at all.

    On the trail, it is almost like riding a mountain bike. Had a few short sections of trail that were used to cut back and head home. Handles well on the rough and does not feel completely out of place riding on trail.

    At the end of the weekend I had been on the bike for ~5 hours. I know that I am officially a weird bike nerd who thoroughly enjoys having ridiculous bikes. It is awesome. Being on a bike should not be painful. If you do not enjoy it, do not do it. I do not like being on a road bike, which is why this is now far from a road bike. That is just me personally. If you get this frame, which I fully encourage, make it your own. Get out there. And ride.
