The DMR DeathGrip is the second collaboration between DMR bikes and Brendog. ‘I wanted to make the ultimate grip to go on all my bikes: AM to DH. I combined the following features and the DeathGrip is what we ended up with!’ Brendan Fairclough.. • Tapered Core for Security.. • Waffle and Knurl for Grip.. • Mushroom for comfort.. . We started with an internally tapered single-lock core grip and wrapped Brendan's design around it in soft Kraton compound for the ultimate mountain bike handlebar grip.
