Description

This is a right side insert for our round, rear 1-1/2" Wright style and flat mount dropouts. It is compatible with the Shimano mountain standard for Direct Mount derailleurs, some Shimano E-Thru 12 mm skewers (see Related Products below) and a 12 mm hub. Made from black anodized 6061 aluminum, it has a derailleur hanger for multi-speed applications and comes with two M4 mounting screws.

Included is a 14 mm long retainer and M4 x 8 mm button head cap screw that hold the Shimano nut captive. Install the wheel and skewer with the flanged (larger) portion of the nut in the recess of the dropout. There are nine notches in the retainer that index the notches on the nut. This allows the closed position of the skewer to be adjusted every 40 degrees for optimal location. If none of these positions work, the retainer can be flipped over to utilize nine more positions that are 20 degrees out of phase from the original positions.
