Tech Support

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin... Make sure you use the Carbon Assembly Compound included with your frame, and use some common sense.

You will not damage your frame by overtightening the seat collar, assuming you have a 27.2mm seatpost in there.

What Kind of Derailleur Does The Highball Use?

The carbon fiber Highballs (both 27.5 and 29-inch versions) use a high direct-mount, bottom pull front derailleur. The aluminum version uses a 34.9mm clamp-on bottom swing/top pull front derailleur. 

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 rear hub do I need?

This bike uses a 142x12 through-axle rear hub, and includes a DT RWS axle.

What size seat collar do I need?

Bikes with a 27.2mm seatpost require a 31.8mm seat collar. 

What size seatpost do I need?

This bike uses a 27.2mm seatpost.  Always ensure it is inserted a minimum of 4" (100mm)

What's the largest chainring I can use on the HIghball?

If you want to use a single-chainring drivetrain on our new Highball, a maximum of a 36-tooth ring is your best bet. A 38-tooth ring will fit, but it's very tight. Any double-chainring drivetrain will work; we've checked a 42/30 combo, and it's no problem at all.
