Sometimes your riding calls for the security of a dedicated single-ring and chain guide on the way down, but you still need the climbing power of a granny to get you back up to the top of the run. If your budget can't handle a HammerSchmidt, a two-ring crankset and a Truvativ ShiftGuide Team might just do the trick.

The Truvativ ShiftGuide Team incorporates all of the features of a good single-ring guide: a versatile, lightweight and adjustable chromoly boomerang that easily mounts behind the driveside bottom bracket cup, a micro-adjustable upper composite guide box, and a quiet-running lower roller complete with a sealed cartridge bearing at its center. When mated with a 22/32T or 24/36T two-ring crankset, an outer guard, and a standard triple front derailleur, the combination yields a healthy dose of security and the reassurance of knowing you'll never drop a chain - to either side - ever again. 290g.
