Product Details

Introducing the brand-new model from Transition, Sentinel with their new SBG (Speed Balanced Technology).  This basically means longer wheelbase, slacker head angles, longer reach amongst other fine tuning. What this equates to for you is better stability, increased confidence, improved traction and better climbing characteristics.

Alongside those significant improvements there is the excellent RockShox Yari RC Solo Air up front giving you 160mm of super smooth plush travel and for the rear there is a RockShox Deluxe RT shock which is as good at climbing as it is at descending. A solid and dependable SRAM NX drivetrain and the SRAM Level T brakes will slow you down when things get a bit too furious.

Keeping you rolling are the tough WTB STP i29 29 inch wheels coupled with the super grip Maxxis Minion II tyres. Finishing with RaceFace Aeffect R stem, RaceFace Chester Bar and the RaceFace Aeffect dropper Seatpost.  The exciting new Sentinel has everything needed to tackle all your trail riding or Enduro adventures.
