Shimano Deore LX Rear Derailleur - Low Normal (Medium Cage)
$60.99
Details
Shimano's Deore LX Rear Derailleur is built to withstand the rigors of off-road riding with a lightweight and rugged cold forged-aluminum body and low-friction pivots for incredibly easy and smooth shifting. And the LX features 11-tooth pulleys, which alternate chain-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: 44/29 chainrings and a 11-28 cassette: (44 - 29 = 15) + (28 - 11 = 17) = 32-tooth chain-wrap capacity.
Largest cog this derailleur can handle: 34 tooth
Weight: 278 grams
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.
