Park Tool Spoke Key SW-13C - Mavic

Comfortable, vinyl dipped, two-sided spoke wrench is designed to easily access Mavic® fittings, including the Mavic® SSC Ksyrium and Crossmax SLR wheels. The smaller end fits six splines of the integrated nipples with 5.65mm OD splines, and 7mm thread size nipple. These are found on the R-sys wheels. (This is equal to the sizing of the Mavic "M40652" wrench.)
The larger end fits six splines of the 9mm spline OD of the threaded eyelets of the "FORE drilled rim adapters" found on rims such as the Mavic® XM819, EX823 and Speedcity wheels. (This is equal to the sizing of the Mavic "M40630" or "M40494" spoke wrench.)
