They just have to be different, don't they?
Take control of those pesky Mavic spoke nipple systems with the Park Tool SW-13 Spoke Wrench. The small end accommodates integrated nipples with the 5.65mm OD splines and 7mm threaded nipples. The large end fits the 9mm spline OD eyelets of 'FORE drilled rim adapters' used on the XM819, EX823, and Speedcity wheels.
