Competition-Ready from the Ground Up – The Griffin Evolves Again

The Radio Griffin Dirt Jumper Bike 26 Inch – Cobalt Green takes the proven Griffin platform and turns it up a notch with a stunning new finish and upgraded component mix. Built for riders who want a responsive, mid-level dirt jump bike that can take on the pump track, skatepark or slopestyle line with ease.

Born to Perform on Dirt, Park, and Street

With its competition-spec 6061-T6 alloy frame, tapered head tube, and forged yoke, the Griffin delivers incredible strength without the weight penalty. The agile geometry and dialled build make it a weapon for riders looking to push their skills further — from flowy lines to tech combos. Now finished in mesmerising Cobalt Green, it’s one of the most eye-catching dirt jumpers you’ll find on any track.

Premium Components Straight Out of the Box

Outfitted with parts from Maxxis, RST, Tektro, Race Face, and FSA, this mid-level machine rides like a pro setup. A 100mm RST Dirt RA fork takes the sting out of big landings, while the mix of Tektro mechanical front and hydraulic rear brakes provides precise stopping power. Double-wall Radio DB32 rims, sealed hubs, and Maxxis DTH 2.3″ tyres round out a bombproof wheelset built to handle abuse. The Griffin is pure progression on two wheels.
