Burgtec Bartender Pro Greg Minnaar Signature Grip Next-Level Grip Design The Bartender Pro is the next level in grip design for Burgtec. Burgtec collaborated with 3x World Champion Greg Minnaar over the 2018 season to hone the construction of the grip to produce unrivalled vibration dampening. The unique supple pattern, combined with 30A rubber compound, combines control and comfort in equal measures. Whilst a 31. 5mm diameter gives an ergonomically pleasing feel, even on the most white-knuckle tracks. To top it all off, it's securely clamped by a 7075 aluminium collar and stainless-steel bolt.
