Shimano XTR Rear Derailleur, Top Normal (Long Cage)
$224.99
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.
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
Weight: 197 grams
Top Normal means that the derailleur spring assists shifts to the smaller cassette cogs, which is the way most rear derailleurs work.
