Our own Silver crank in an external variation. We had these made for the Gus and Susie frames, but it'll work well on any of our bikes and tons of others too. It has a 104/64 BCD so you can fit teeny chainrings on the inside for easy uphills on dirt.
The arms are cold forged out of 7075 T6 aluminum, and strong enough for any rider. Lengths 167, 172, 177, and 182.
A good bottom bracket is included, hence, the slightly higher price than our square taper crank.
For 68mm BB shells, use two spacers on the drive side and one on the non-drive.
For 73mm BB shells, use one spacer on the drive side.
169mm Q-factor with supplied BB.
This variation comes with a BB and arms. Nothin else! A good choice if you want to use a Wolftooth ring or something similar for a 1x set up.
