The first mountain bikes were made out of steel, but that is not why we decided to make these. We chose steel because it offers the best combination of value, comfort, and resiliency of all the popular frame materials. Hardly any folks these days buy a steel frame as their first mountain bike. It's those who've ridden a while and have tried aluminum and full suspension -- who come a knockin'. We do 29ers, 26ers, and 650B'ers.

The Jawbone A-Type frame is the perfect platform to build drop bar mountain touring and bike packing rig. While it is still game for riding gravel and singletrack, it is in its element when packed up for your next adventure.

The Fog Cutter is an endurance road/road sport design. We designed it to fit fatter tires, but its geometry makes it handle like a road bike rather than CX or gravel bike. It can float you over chewed up asphalt better than most bikes in this category. This is the frame you want for grand fondos, long days in the saddle and the most demanding commutes.
• Tire clearance for 700c x38mm with fenders (some front derailleurs will limit tire clearance) and 650b x 42mm • Fits 1-1/8" headset (EC34/28.6|EC34/30 headsets)
- 27.2mm post size
- 7 sizes: 48, 51, 54, 56, 58, 61 and 66cm

RIFF V.2.0 (27.5″ TRAIL HARDTAIL)

The version 2 of the Riff offers practical updates to features and geometry without going all-in with "progressive geometry" that almost every brand has adopted. Our reason is that we wanted to keep this frame a hardtail that's great for bike packing and has a familiar-feeling on long days in the saddle on rolling terrain. "Progressive geometry," which can be awesome for steep technical trails, can feel less fun or even uncomfortable on flatter terrain.
We did opt for more reach, a slightly steeper seat angle for more efficient climbing and shorter seat tubes to benefit dropper post use. We also got rid of seat tube bottle bosses on some sizes to allow longer dropper posts to be used.
Rear hub spacing is finally BOOST 148.
Still a highlight on the Riff are the tough Broski Sliding Dropouts which allows to tune your chainstay length as well as allow you to run the bike single-speed, with derailleur gears or hub gears.
– Tange Prestige heat-treated butted CrMo steel
– Geometry is optimized for 120mm forks. Will work well with a 100mm fork, too.
– IRD Broski Sliding Dropouts allows geared and single-speed builds with easy wheel removal
– S-bend seatstays and chainstays
– Rear rack and fender eyelets
– ED coating inside frame and underpaint increase rust resistance
– Disc brakes only (ISO tabs)
– Dropper post cable routing runs on downtube and inside the seat tube
– Boost 148mm rear hub spacing
– 3 pack mount and water bottle mounts on down tube (LG size has a set of water bottle mounts on the seat tube as well. Seat tube bosses are left off the other sizes to better fit dropper posts)
– CNC-machined 44mm headtube: Will fit 1-1/8″ steerers with a ZeroStack 44 headset or fit tapered steerers with a ZS44 upper assembly and external cup (EC44) lower assembly
– 31.6mm post size/34.9mm frt. der. size/34.9mm seat collar(not included), 400mm(or longer) rigid post recommended.

Wolverine B-Type
Regular price

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 (Rohloff, etc). With a split seatstay, it is compatible with the Gates Carbon Belt Drive.
2023 brings our version 4.1 B-Type that adopts flat mount brakes on both frame and fork. Version 4.0 which uses the IS brake mount will be available most of 2023. Flat mounts have become the primary standard for road brakes, but IS mounts are still more convenient for builds running flat bars, MTB drivetrains, or larger disc rotors
(Also check out the Wolverine v.4.1 Type-A, which adopts slightly more modern standards! See chart in photo gallery for their differences)

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. The primary differences between the version 3.0 Wolverine and the 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. NO frame break for Belt-Drive. (See chart for other differences between A and B)
