Product details:

Shimano's new Direct Mount Rear Derailleur system gives more space around the rear frame dropout resulting a simpler, cleaner look, easier rear wheel removal but also allows frame designers to shorten chain stays, increase axle sizes and move suspension pivots. A Single tension spring prevents contact with the chainstay resulting in a silent ride. Shadow features a super low profile design that reduces the risk of damage from trail side hazards and a direct cable routing prevents snagging from any trail side hazards.
