Transition Spire - 2023-24, Medium

2023–24 Transition Spire 29 — Size M, Full Carbon MTB, Shimano XT AXS 12-Speed

The Transition Spire 29 is built for serious all-mountain and enduro riding — a perfect blend of big-travel confidence and modern trail precision. Its full carbon frame paired with a Marzocchi Z1 fork (170mm) and Fox Float X2 rear shock delivers plush suspension that’s ready for anything from technical climbs to massive descents. The Shimano XT AXS 12-speed electronic drivetrain provides crisp shifting, while the XT brakes and dropper post add full control. Weighing in at 32 lb, it’s a tough yet surprisingly efficient machine.

Why we love it:

The Spire 29 is one of those bikes that just makes you want to ride faster. It’s incredibly stable at speed, climbs better than a 170mm bike should, and feels bombproof yet playful. A true shredder’s bike — built for riders who don’t hold back.
