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.
This carbon GX spec bike has a Zeb Ultimate fork and Super Deluxe Ultimate shock. All models have four piston brakes and 165 mm cranks.
We have some bikes arriving for stock, but more often than not they are sold before they arrive, so if you would like to order a bike, please call us on 01330 828562 to leave a deposit. (You can read more about ordering bikes from 20Twenty here.)
