First Look: Transition's 2018 Sentinel Carbon is Engineered to Party

For those of you who have been Sentimental over Transition's new Sentinel but only ride carbon, the wait is over. It's available in S, M, L and XL sizes and boasts all the same great features, hardware, and parts kits as the alloy model. Transition shaved an impressive 2.5-pounds (1.1kg) from the aluminum model, helping this modest 6.8-pound (3.1kg) carbon beauty of a frame to become a true rocket ship.

In Action

"When dreaming up what to shoot for the Sentinel I couldn't narrow it down to one style of riding, so we shot four locations/riders – all of which found the Sentinel to be right at home. Enjoy!" - Skye Schillhammer

 

Geometry

Transition's Speed Balanced Geometry concept incorporates the following five key geometry features:

  • Increased frame reach
  • Slacker headtube angle – Allows the fork to absorb impacts better on all angles, positions the front wheel further forward, and reduces deflection and dive.
  • Steeper seat tube angle – Brings rider more forward, aids in climbing traction, and reduces seated sag.
  • Shorter stem – Equates to a modest increase in total reach.
  • Shorter fork offset – Brings the front axle more rearward and under the rider which further increases front tire traction. Works in unison with the shorter stem length to provide a more direct steering input.

    Brandon, it's "plastic fantastic" not vice versa. What would Jesse Jackson say?

    Looks amazing! Hoping the Scout(and Smuggler, and Patrol) gets the same treatment.
