About the Bike
The Pinnacle Arkose was a gravel bike before we were using the term regularly. For 2020 it’s had the most significant re-design in its 7 years in the market.

The new Arkose is a benchmark for the versatility this type of bike can offer. The new Arkose frame has full compatibility for wheel size (650B x 52C or 700C x 45mm), rear axle and Di2/cable gearing options. Add this to proven handling that sits on that fine line between the best of road and gravel bike characteristics and it’s a contender for being your one do-it-all drop bar bike.

The Dirt specifications on the 2020 Arkose frameset are ready for those who want to explore the trails at the end of the road. Equally at home on road or byway, Arkose Dirt is for the opportunist rider who goes where their mood takes them. Equipped with a 48-32 tooth chain set, wide ratio cassettes, WTB Riddler 700 x 45c tyres and a more comfortable & relaxed contact points, the Arkose Dirt keeps all route possibilities open.
