The Big Dipper is wider than average, ergonomic in all of the hand positions of the bar, and rated for off-road use (ISO 4210 mountain bike strength/fatigue testing). It has a gentle backsweep for ergonomic riding on the tops of the bar and a short reach to minimally impact your stem length for a bar this wide. The Big Dipper is produced with triple butted and heat treated 7000 series aluminum, making it strong and light for its width. Tumbleweed've ridden countless drop bars off road on many different bikes, all informing their design. This bar has been a long time coming and we're sure you'll love it.
