Spire Alloy XT 20Twenty Bike

  • SALE
  • Regular price £5,399.95
VAT included.


You might have seen elsewhere that there are no more XT Build Spire's for 2022. We're not giving up that easily!

We've managed to be able to put together a Spire that's very similar to the out-the-box XT build, only with a few upgrades, at the same price as the bike you've been haplessly scouring the internet for.

Upgrades over the standard sec include custom-made wheels with Hope Pro 4 hubs (in whatever colour you like, they'll be built specifically for you) and DT Swiss EX 511 rims. Tyres are a step-up too, with a DD Assegai front and either a DD or DH Assegai rear.

The Fabric saddle is the change your hee-haws will appreciate the most, though!

  • 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.

We specialize in custom-built enduro bikes! If you'd like to change any parts of this bike, please get on touch for an awesome deal!

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!
