The Pinnacle Arkose is the benchmark for versatility. It’s been conquering mountain passes long before you were told you needed a "Gravel" bike just to go off tarmac. A real drop-bar legend on the dirt. With clearance for 700x47c or 650Bx50 tyres, triple bottle cage mounts, internal cable routing compatible with electronic groupsets and dynamo lights, full coverage mudguard and pannier rack mounts, The Pinnacle Arkose could be the perfect companion for cycling off into the sunset. Or just to the shops. As we said, this is one versatile bike. For 2021 we’ve simplified the line-up, updated the geometry and made it unisex to make it easier for you to find the right Arkose for you.
The Arkose 3 comes equipped with Shimano’s genre defining GRX groupset. 46-30T chainrings paired with a wide range 11-36T cassette offer low gravel griding gears whilst maintaining a suitable top-end for road cruising and descending. Hydraulic disc brakes offer lower maintenance whilst improving feel and response at the lever. WTB’s excellent Serra wheelset is wrapped in fast rolling and comfortable 45mm wide WTB Riddler tyres.
Whether you ride for pleasure, adventure or fitness we’ve got a bike that will suit every kind of rider. Even those who just want a bike to pop to the shops on. We believe that with the right bike, anyone can fall in love with cycling.
