Derailleurs
Bike World Iowa has all the options you need to make a choice you can be confident with
Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. The Direct Mount uses less parts and provides a solid connection to your machine. The Shadow design tucks the rear derailleur closer to the wheel, which keeps it out of the way of roots and rocks as you're flying down the trail. A strong spring prevents chain slap, reducing noise while on the trail, and improving chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.
Whether you're attacking a tough climb or cruisin' with a tailwind, you want a front derailleur that shifts quickly and reliably. The Ultegra Front Derailleur does just that with wide pivots for rigid, flex-free shifting, a clear-coated-aluminum body and Shimano's precise engineering.
