Description

This is a right (drive) side replacement insert for all of our adjustable rocker dropouts and is compatible with the Shimano E-Thru 12 mm skewer only. It is made from black anodized 6061 aluminum and has no derailleur hanger for single speed applications.

Included is a 14 mm long retainer and M4 x 8 mm button head cap screw that hold the Shimano nut captive. 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.
