Nowadays, bikers ride what used to be called downhill trails on enduros. The trails are getting rougher and the demands on the gear and rider are greater. The E 1900 SPLINE has been developed to deal with precisely these re-quirements. With its stiff aluminum rim, lightweight straight pull spokes and proven DT Swiss hubs, this wheel is well-armed for any challenge. The balance of weight and stiffness will put a smile on your face, whether you’re riding up or downhill. After all, you won’t find lifts to many of the best trails.Pro LockPro Lock is a process where a patented, dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Retruing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.
