Basic idea: A drop bar bikepacking/touring bike that fits true mountain bike width tires (up to 29 x 2.25" and 27.5 x 2.6" with decent mud clearance -- depending on frame size and drivetrain choice).
- More three pack mounts
Why would I try this over a Juice or Riff or other hardtail frame for bikepacking?
- Slightly lighter in weight
- More responsive handling on asphalt
- More sizes for better fit
- Geometry has higher stack to make it easier to use the drops on drop bars
Why would I try this over a Saga Touring Frame or similar heavy duty touring frame?
- Not super stiff, so still enjoyable to ride off-road unloaded or to commute on.
(We don't tout the Jawbone as a traditional touring frame, but it can do the job, if you can live without a kickstand.)
The B-Type is for those who like to tinker and appreciates practical bells and whistles. The Broski thru-axles allow to run the bike with derailleurs or geared hubs like Rohloff and if either fails on a trip, it can be run as a single speed. The sliders on the B-Type allow you shorten the chainstay to 435mm for a sportier ride or 455mm for a more stable ride.
The B-Type maintains compatibility with QR wheels standard. We know there are quite a few of you who find QR wheels quite reliable for long distance touring and gravel. It is the technology you know and it is still easy to find and cheap to replace.
|Optional fork for A-Type:
Steve Potts Type II-R MTB fork. Unique looks. Note: Unlike the frame having flat mount ,
the fork has an IS mount. This makes it easier to run a 180mm rotor, if that is your choice.
|Optional fork for B-Type:
Simple efficient unicrown design. Has three-pack mounts angling rear and front.
Plus dedicated pannier rack mount on inside and outside the leg.
