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.

Shimano's SPD cleats are perfect for all your SPD-compatible pedals. If your entry and exit isn't what it used to be, a cleat replacement is just what the bike doctor ordered. These are a direct replacement for the cleats supplied with most Shimano SPD pedals.

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.
