Spire Alloy Frame

The Spire is Transition's all new 170 mm 29er with the latest version of Transitions "Giddy Up" suspension platform, with improved small bump sensitivity and mid-stroke support.

The new Spire's frame has a flip chip at the lower shock mount, and adjustment at the head tube, with a ZS56/ZS56 press fit headset, which you can replace with an angleset to change reach or head tube angle.

Chainstay length increases on the XL and XXL size frames, from 446 mm on the S, M and L bikes to 452 on the XL and XXL bikes, and there's clearance for a 2.6 tyre.

This alloy frame kit includes a ZS56/ZS56 headset and a Fox X2 shock.
