Some of these wheels use Tracomp non-drive side and front spokes. The Mavic TraComp tubular carbon spoke used in the 2016 Mavic R-SYS wheels on the non-drive side of the rear wheel as well as the front wheel. These spokes have the new N7 nipple (6.4mm) and thus requires the new M7 truing tool. These are far from traditional spokes are require a specific procedure to replace and to true a wheel. Your lack of following the instructions set forth by Mavic will likely result in damaging the spoke and having to by another replacement... Consider yourself warned! Since these spokes are susceptible to damage in shipping, I take special care packaging then for shipping.
Note: Tracomp spokes for these model years have black ends.
