Derailleurs

Bike World Iowa has all the options you need to make a choice you can be confident with

SRAM's X0 Front Derailleur is made from cold-forged aluminum and chrome-plated steel for exceptional reliability and a race-worthy weight. It boast’s SRAM’s X-Glide technology for super-smooth and lightning-quick shifting even under load.
SRAM's X9 Rear Derailleur is favored by everyone from weekend rippers to marathon riders crossing the Alps. It offers a great balance of durability, low weight and slick shifting. The X9 features an aluminum/composite construction, SRAM's 1:1 actuation ratio and direct cable routing for quick, reliable shifts. Plus, this beauty is built to last so you can sample singletrack for years to come.
Shimano's 105 Braze-On Front Derailleur sports extra-wide beefy pivots, which eliminate flex for lightning-quick shifts. Plus, the clear-coated aluminum body and chrome-plated-steel cage will last for years.
Shimano's 105 Rear Derailleur for triples is a sweet upgrade. Shifting is almost effortless thanks to the light-action spring. Plus, the 105's top pulley stays a uniform distance from each sprocket so shifts resonates with the plunk of exact gear engagement. And the wide outer-pivot design increases rigidity for precision shifts every time.
Shimano's Deore XT Rear Derailleur handles the pressure! Its low-normal design moves the chain to the easy-pedaling gears (large cogs) with very little shift-lever pressure so it's easy to shift while climbing. Plus, the wide pivot design increases rigidity and longevity for miles and miles of crisp shifts. This combination of efficiency and light weight have long made the XT a favorite of racers and freeriders alike.
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.
Ride it all with Shimano's SLX Dyna-Sys 10-Speed Shadow Rear Derailleur. The radical design means that the Shadow is super-low profile; it barely protrudes more than the quick release nut. Direct cable routing fires off shifts super quick and reduces the chance of the cable snagging on roots and rocks. A stronger spring keeps the body more stable when blasting through technical terrain at speed and yields a firm, crisp shifting feel. Plus, the bracket axle keeps the derailleur body from contacting your chainstay and reduces chatter so you just concentrate on the best line.
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.
If you're looking for a quick-shifting, super-light front derailleur, you've found it in Shimano's Ultegra. The wide pivot-link design suppresses flex for light, fast and precise shifts, even under load. And this fine derailleur is built tough for reliability and durability, too.
Shimano's Ultegra Di2 Front Derailleur makes the dream of lightning-quick front shifting a reality. Its intelligent electric brain senses the location of your chain, providing impossibly fast, smooth and accurate shifting, even under load, with just the push of a button on your Ultegra Di2 shifter (sold separately). It also auto-trims to maintain clearance between the chain and cage no matter what chainring/cog combination you choose. You'll never miss a shift again and will hit the right ring faster than ever. And, because there are no cables and housing to stretch, wear or fail, you'll also love Di2's amazingly durable, reliable and silent operation.
Shimano's Ultegra rear derailleur benefits from trickled-down Dura-Ace technology for top-notch shifting without the high-end price. It boasts a light and reliable cold-forged-aluminum body with a wide pivot design that boosts rigidity and speeds and smoothes shifts. Plus, the fluorine-coated pivots minimize friction for nearly effortless shifting. The Ultegra features one sealed-bearing pulley and oversize pulleys, which are silky smooth, ultra quiet, high mileage, and designed to keep out dirt and water.
If you're looking for a quick-shifting triple front derailleur, you've found it in Shimano's Ultegra SL. The wide pivot-link design suppresses flex for light, fast and precise shifts, even under load. And this fine derailleur is built tough for reliability and durability, too.
