Wolverine (v.4.0) Type-A (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.

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 in photo gallery for other differences between A and B)

  • 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) 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.

  • Bicycle Quarterly: Fun Versatile Bike

    [For an older Wolverine model. The Wolverine A-Type does not have bosses for downtube shifters] 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

    [For an older Wolverine model] "...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."
