Wolverine (v.4.0) Type-B (Adventure/Monstercross)

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. With a split seatstay, it is compatible with the Gates Carbon Belt Drive.

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

Wolverine (v.4.0) Type-B (Adventure/Monstercross)

  • How to take care of the Wolverine's unique rear triangle?

    1) Follow our official max tire guidelines which is 700c x 45mm with fenders and 29 x 1.95 without fenders.

    Why is using too big a tire a possible problem?
    a) To fit a fatter tire than recommended requires user to slide the insert to the rear of the dropout. Sliding the insert to the very rear creates extra leverage on the dropout and the frame versus having it in the center or front of the slot.
    b) Using fatter tires makes the rider think he/she can ride more aggressively than the frame tubing is designed for. The Wolverine is not an XC/trail bike.

    2) A split in the seatstay allows the frame to take a drive belt. Periodically check to make sure the bolts holding the right seatstay together are safely tightened. If you find them loosening, try a stronger type Loc-Tite (especially if you don’t plan on using a belt) If you hear an unusual noise or flexiness while riding, definitely check those bolts. Loose seatstay bolts don't usually make for dangerous riding, but it does make the chainstays work harder.

    3) Make sure the bolts holding the sliders are safely tightened at all times.Those bolts should be tightened to about 25nM. Make sure sliders are evenly aligned. Loose bolts here can be hazardous to riding. Try carbon paste on the sllider contact areas, if you are experiencing slipping even though the bolts are adequately torqued.

  • 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.

  • Built it Up So Many Ways

    “I can attest to the awesomeness and versatility of this frame as I've had 2 (built by Natural Cycleworks) and they were built up almost everyway imaginable. (WhatBars has built this up with Alfine 8 hub, Microshift thumbshifter and a Gates belt drive and has used it for a winter bike up in Winnepeg area. Also single-speed. Flat bars. Alt bars Sometimes a large front bar bag. or a basket. Large seat bag. Tested a lot of different bags)”

  • The favorite!

    “If you were to ask me what’s my favourite bike from my collection I would definitely answer “The one I’m Riding on!” In all reality this bike is the most versatile. We’ve conquered dirt, mud, steep black diamond descents, climbs of all kinds and 1000’s of km of dirt/paved roads, fully loaded. I might love my Wolverine a little more but don’t you dare tell the rest of the fleet, I don’t want them to get jealous.”

    “Soma Wolverine review: [for an older Wolverine model, current Wolverine has a Tange Prestige rear triangle now] God damn this bike is pretty, The frame definitely required more preparation, but as a qualified mechanic that was not an issue for me. the Molten Orange paint (not powder coat, paint.) is just ridiculously pretty. the Tange IRD drop outs look (And for the love of god, FUNCTION) worlds better than the Surly drops. they are Set and forget. completely satisfied. Though, it does look like mounting racks on these dropouts will be a bit more tedious. the rack bolts would have to be bought short, or cut down, or spacers. not a big deal, but it would add a few minutes work. The head tube on the Soma is several CM taller, and the top tube has a very subtle, almost un-noticed rise to it. this allowed me to use fewer stem spacers than on the Surly and still keep it looking normal. It's not an ugly rise on a giant head tube (Like the Salsa Vaya or Specialized Awol has) so the aesthetic integrity of the frame is not really "compromised" For two seemingly identical bikes of the same size, there are some very subtle differences in geo. there is a 6 degree difference in fork rake (44 for the Surly, 50 for the Soma. I don't know which one is steeper(math, ew!), but The Soma feels more lively and responsive.) the top tube is a whole 5 millimeters longer on the Soma. yeah, Geo. The Soma feels more like a road bike in terms of handling. While I found rake for both bikes, head tube angles and fork dimensions don't seem to posted online for the Wolverine. So I just have to tell you how it feels. it feels like it was designed for pavement. Tubing to tubing there is just no contest. the Soma rides, nay GLIDES. Those who can't tell Tange Prestige from Surly Natch are people who I want to say condescending things to. Like Grant Peterson does when someone likes a brake pad he refuses to sell them. It's just amazing. for my old bones on long commutes, there is no better ride (that I can afford) I appreciate that the thickness of the tubing is a huge part of this. and that technically this tubeset is not as indestructible as the Surly, but I had a Soma Groove before the Surly, it took 3 years and winters of abuse and several wrecks and never broke or showed any signs of wear. so for a commuter, I have complete confidence. Tange Prestige is NOT used in the seat and chainstays, so the rear end is plenty stiff, especially when paired with the Tange drop outs, it feels stiffer than the surly (only in that regard, though.) The Soma Forgives me where I want it, and is stiff where I want it. Finding where this bike falls short in comparison to the Surly is tricky. The surly definitely has a more durable finish. more frame prep, It's going to be an all around more durable bike. But I take care of the paint on my bikes. I can prep my own frames and I'm a commuter, so those points don't really matter to me. Though they definitely matter to many. The Surly has a truly horizontal top tube, very traditional and aggressive road bike looks. the Soma looks a bit like a hybrid. Surly doesn't put their decals under the paint. Soma does. so you can't change them. I made the right choice going to the Soma. but I appreciate that won't be the right choice for everyone.”

  • BikeHacks.com's Wolverine Review

    "A couple of things struck me on my first couple of rides aboard the Wolverine. First, I had forgotten how supple and lively a steel bike can feel, even at this price point. The ride quality improvement when you jump from a basic 4130 tube set to even an entry-level, name-brand tube set is significant.Secondly, the big Shikoro tires rolled very well and were incredibly comfortable. This was my first extended test of SRAM’s 1×11 drivetrain on a drop-bar bike and I’ve come away impressed. At first, the larger ratio jumps between gears were noticeable, but I quickly acclimated."

    "Just as Soma intended, the handling of the Wolverine straddles the middle ground between drop-bar commuter, monster ‘cross bike, and light touring rig. Handling is quicker than you’d find on a true touring rig but slightly more relaxed than you’d find on a cyclocross bike."

    "Off-road, the Wolverine feels great on graded dirt surfaces or anything that could be loosely classified as a road. When you turn onto singletrack the Wolverine holds its own but the road-oriented geometry requires quick reflexes. With its plethora of rack options, the Wolverine is ready for adventure.

    However, it’s important to keep in mind this is designed as a light touring bike. It’s more than up to the task, but the lighter your load the more fun you’ll have. If you’re looking for a round-the-world-with-the-kitchen-sink rig, there are better choices on the market such as Soma’s Saga touring bike.

    With a reasonable weekend’s worth of gear, the Wolverine’s handling and frame stiffness both felt great. In day-to-day use as a commuter rig, the Wolverine was a treat. Handling is lively and fun if you’re feeling frisky, yet mellow enough to let you zone out and decompress on your way home from work.

    Set it up with fenders and commuting tires for weekly commutes. Rip the fenders off and throw on some knobbies for a long weekend gravel bike packing adventure. Run it as a single speed commuter during the winter to save your drivetrain. The options are nearly limitless if you enjoy tinkering.

    No doubt, there are a lot of bikes on the market promising versatility. Soma Wolverine is a fine example of one that offers highly functional versatility with a few features, such as the sliding dropouts and belt drive capability, that set it apart from entry-level offerings. It’s easy to see this as a versatile drop-bar solution for anyone outside of the performance road or ‘cross racing realm."

  • SOMA(tic) Tangerine Wolverine

    [For an older Wolverine model] 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.

    [For an older Wolverine model] 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.
