Tech Support

Can I mount a chainguide to my bike?

Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting.  Most chainguides on the market that are made for this standard should work.

Can I mount a front derailleur?

No, this bike is not compatible with a front derailleur.  Single ring only!

Is the 148x12 derailleur hanger the same as the 142x12 hanger?

No, it's not. We had to make a new derailleur hanger to go with the new dropout. They look similar, but the easiest way to tell them apart is the finish. Our 142x12mm hangers have a bead-blasted finish, while the 148x12mm hangers have a smooth, machined finish. 

What Happens if I run a 150mm Fork with 29" Wheels?

If you keep your fork at 150mm when swapping from 27.5+ tires to 29" tires, it will result in a bottom bracket height increase of 3.4mm, and your head angle and seat angle will get 0.4 degrees slacker. 

What Kind of Headset Do I Need?

This bike uses an integrated headset with drop-in bearings and molded-in bearing races. The SHIS measurement is IS41 (upper) and IS52 (lower). 

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size seatpost do I need?

This bike uses a 31.6mm seatpost.  Always ensure it is inserted into the frame a minimum of 4" (100mm).

What's the Biggest 27.5+ Tire I Can Fit?

2.8in tires fit really nicely, and 3.0s will fit, but they can be a bit tight. If you have a lower-profile tire, and don't see a lot of mud, you can definitely run a 3.0. If you're looking for more aggressive rubber, or ride in muddy conditions regularly, you'll want to stick to 2.8s. 

What's With The Chip?

The reversible chip at the shock mount is designed to maintain the frame's geometry when swapping between standard 29-inch tires and 27.5+ tires. The "Low" setting is designed for 29er use, and the "High" setting for 27.5+. While 27.5+ tires have a diameter that's similar to the 29er tire, it's not quite equal, so reversing the chip is a must to maintain the handling characteristics. 

Flipping the chip to "High" without swapping to 27.5+ tires results in an increase of 3.1mm to bottom bracket height, and an increase of 0.25 degrees to your head and seat angles.
