Comfortable, vinyl dipped, double-ended spoke wrench for select Mavic wheels using the integrated M7 nipples. Smaller end fits 7-spline nipples with a 6.4mm outside spline diameter. These are found on the R-sys wheels. The larger end fits the 6-splines of the 9mm OD of the threaded eyelets of the FORE drilled rim adapters found on rims such as the Mavic XM819, EX823 & Speedcity wheels. (This is equal to the sizing of the Mavic 108 471 01 wrench.)
