This is an optional set of Exotek DR10 Aluminum Rear Clamping Hexes. These precision machined 7075 aluminum hexes were developed for the DR10 and DB10 models, and feature looser steel cross pin tolerance that unlike the stock plastic hexes, allow you to tighten the wheel nuts without binding the bearings. Package includes two hexes and M2 hardware.

NOTE: Do not over tighten the M2 clamping screws.
