Transition Spur Carbon XT Di2 (2026)
Built for modern XC and “downcountry” riding, the Spur blends a lightweight carbon chassis with 120mm of rear travel and a 130mm Fox 34 SL up front to create a bike that feels fast everywhere. It’s sharp and efficient on climbs, but far more composed when trails get technical than a traditional XC race bike. If you want a bike that can line up for race day and still feel playful on everyday rides, this is the Spur’s lane.
Key highlights
- 130mm / 120mm travel built for aggressive XC and fast trail riding.
- Fox Factory suspension for top-tier small-bump feel and control in rougher terrain.
- DT Swiss XR 1700 wheels + Forekaster 3C EXO+ for speed with real trail confidence.
- Shimano XT Di2 for fast, consistent shifting under load.
Design and durability
- Carbon frame with 120mm rear travel.
- UDH compatibility and clean internal cable routing.
- B.O.O.M. Box internal frame storage for ride essentials.
- Size-specific chainstays for consistent handling across sizes.
Ride characteristics
- Efficient pedaling for long climbs and big days.
- More confidence on steeps and rough descents than older “pure XC” bikes.
- C.H.I.P.S. adjustment helps fine tune handling and bottom bracket height.
- Lively, playful trail feel — built to rail corners and stay engaging.
Fit, setup, and recommended upgrades
- We want every rider to get the most out of their new Spur.
- Local pickup customers: We can help dial in suspension sag, rebound, and cockpit setup before your first ride.
- Shipped bikes: Bikes arrive professionally assembled and test ridden. Our staff can assist with setup questions if needed.
- Recommended upgrades: Many riders choose pedals, frame protection, tire inserts, or a rotor size change to match local trails and riding style.
