Transition Spur Carbon Eagle 90 (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 delivers the precision to charge climbs and thread technical lines with confidence, while staying lively and playful on trail. If you want race-day speed without giving up trail capability, this is the Spur’s sweet spot.
Key highlights
- 130mm / 120mm travel built for aggressive XC and fast trail riding.
- Fox 34 SL Grip X Performance Elite for added control without weight penalty.
- DT Swiss XR 1700 wheels + Maxxis Forekaster 3C EXO+ for speed and confidence on varied terrain.
- SRAM Eagle 90 Transmission for crisp shifting and durability.
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
- Sharp, efficient climbing feel without the harshness of a traditional XC race bike.
- 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 boost, 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.
