New to GT’s lineup is the Helion 27.5 cross country rig. While this tweener-sized bike is aimed at the average XC market, it’s designed with aggressive cross country in mind, with a slightly slacker head angle, a long top tube, and wider bars than a lot of XC riders run.

Key Specs

The Helion features 110mm of travel and 27.5″ wheels. For geometry, the size medium sports a headtube angle of 69.5 degrees and a seat tube angle of 70.5 degrees. For all of the nitty-gritty geometry details, check out these charts:



Angle Optimized Suspension (A.O.S.)

The Helion features GT’s Angle Optimized Suspension which, according to GT, “isolates your pedal forces from the suspension, so all the effort you put into pedaling stays with your pedaling and your suspension only reacts when you need it to.”

Build Kits

The Helion will be available in a wide range of build kits:

    I’ve always thought the pivot/bottom bracket that GT uses seems way to complicated and clunky. The one picture really shows it. Of course, this is just my observation, I’ve never tried one to see how it performs.

      Having logged 500 miles (and counting) aboard the GT Force, I can assure you that while it might look clunky, the suspension is supple and oh-so-smooth through the gnar!

      That’s good to hear, especially considering they are reasonably priced bikes.
