$254.99
Details
There's a good reason why you'll find the XTR Rear Derailleur aboard just about every top-end off-roader. It's super light, durable and shifts like a dream. This cold-forged-aluminum rear derailleur is stiffer than ever and boasts smooth, light-action shifting. The 11-tooth pulleys alternate link contact, reducing wear and smoothing pedaling. Plus, the Low Normal shifting action is super smooth.
An important part of a rear derailleur's job is keeping the chain taut as you change gears. Chain-wrap capacity is a number that tells whether or not a derailleur will be able to do this on the drivetrain you plan to use it on. Calculate chain-wrap capacity with this formula: Chain-wrap capacity = (large chainring - small chainring) + (large rear cog - small rear cog). Example: 46/34/24 chainrings and a 12-34 cassette: (46 - 24 = 22) + (34 - 12 = 22) = 44-tooth chain-wrap capacity.
Largest cog this derailleur can handle: 34 tooth
Low Normal means that the derailleur spring assists shifts to the larger cassette cogs, which speeds and smoothes shifts and greatly reduces the chances of damaging the derailleur during upshifts because you can't force it with the shift levers.
