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 4 comes equipped with the even slicker RX600 GRX groupset. A 1x11 drivetrain simplifies gear changes and drops weight, as does the WTB Speedterra wheelset. A 40T chainring paired with an even wider 11-42T cassette offer lower gravel griding gears whilst maintaining a suitable top-end for road cruising and descending.
