Product Description

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 2 comes equipped with Shimano’s reliable Sora R3000 drivetrain with a super-compact 46-30T chainset from FSA, paired with a wide range 11-34T 9 speed cassette. TRP’s well respected Spyre dual-piston calipers take care of braking, made even better with the upgrade to 12mm thru-axles front and rear. 45mm wide WTB Riddler tyres on 21mm wide WTB ST i21 rims make for a fast rolling, grippy combo on a variety of surfaces. Perfect for little adventures or long days in the saddle.
