Doubletake UPG3.5- Upgrade Mounting Assembly with 3.5" Arm

This mounting system will attach to your current Doubletake Mirror. A mount can be used on either side; to mount 2 mirrors buy 2 kits.

Universal Fit. Every ball kit includes 4 bolts to allow fitment to any bike and eliminate unsightly adapters. 

Larger size. Our ball is 1.125”, and even that small increase in diameter makes a big difference in rigidity. This means you don’t have to overtighten the arm to keep it from moving while riding.

Won't Crush. Our aluminum-filled base ball, coated with high-quality nitrile rubber won’t degrade under extended compression. You won’t have to repeatedly adjust your mirrors, because both ends of the system are designed to last.

Won't spin. We include a lock washer that secures the ball in relation to the bike.

Better hold, less effort. The whole system has been engineered together to keep the mirror from moving, except when it has to in an impact.  

Radial Ridges. The clamping surface at the base has radial ridges to hold the ball more securely. These ridges prevent the arm from unintentionally rotating relative to the base, but without mechanical interference that could be damaged under impact.

Asymetrical Clamping. Because the ball diameters are different, the clamp is located off-center toward the mirror. The larger base diameter creates more stiffness at the bottom, and the offset clamp grips the mirror tighter to equalize rigidity. 

Easy Adjustment. Our low profile thumb nut is 25% longer to make adjustment easy even wearing gloves.  Perfect for aggressive riders- long enough to see, but small enough to tuck away.
