Wolverine v.3.0 Frame
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. With its sliding dropouts, you can turn it into a single-speed CX bike. With a split seatstay, it is compatible with the Gates Carbon Belt Drive.
New v.3.0 has the new and robust IRD Broski Dropouts. We also switched up the welding method to keep more of the tube's overall strength.

Wolverine v.3.0 Frame
What 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 new Center-Track system. Shimano Alfine Di2 does not fit on the Wolverine because the belt line needs of the hub.
Models of Wolverine with the split in the seatstay are now approved for use with belt-drive with Rohloff hubs. With Rohloff for gravel, a 55t front x 19t rear x 115 belt; 440.19 chainstay setting is a good place to start. Use a small front ring for touring and trail riding.
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 actual range on the Wolverine in 425-443mm. It will give you belt length when you type in the gearing you want.
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. 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.

Are there replacement inserts to change my Soma (Juice/B-Side/Analog/Wolverine) with Sliding Dropouts to 142 x 12 thru-axle?
Our current frames with sliding dropout are for 135mm QR's. There are third party slider inserts that will do the trick. E-mail us for the info. We will have our own inserts for thru-axle some time available by Summer 2018.
