Trail Bike (Carbon or Alloy) · 29" or Mixed
Transition's best-selling trail bike, and arguably the sweet-spot 29er on the market. 150mm rear travel, 160mm fork, designed to climb all day in service of the descent. The V3 (2025+) brings mixed-wheel compatibility (flip-chip), Transition's internal "BOOM Box" storage (on carbon frames), size-adjusted chainstays, updated cable routing, and UDH. Available as alloy or carbon; carbon gets internal storage. Horst-link suspension means excellent traction and mid-stroke support. Offered in Eagle 70 and Eagle 90 (T-Type Transmission) builds.
