All new for 2021! A 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, though from what we've been told by Transition the higher setting sounds like the better setting for typical UK trails.
There's more 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. All models have four piston brakes and 165 mm cranks.
Read more about the new Transition Spire here.
- High and low geometry options via lower shock mount flip chip.
- Two chainstay lengths, short on S, M & L and long on XL & XXL.
- New oversized parallel headtube enabling the use of reach or angle adjustment headsets.
- Frame protection on chainstay, seat stay and downtube "shuttle guard".
- EnduroMAX frame bearings.

Pedals
Since most people would change their pedals from whatever the manufacturer supplied, very few bike manufacturers supply pedals with new bikes.
The good news is we have an awesome selection of both flat and clipless pedals!
