Details

Shimano’s 105 Rear Derailleur delivers high-end function with upscale looks. With a body of light, durable cold-forged aluminum in Shimano’s wide-pivot design with their light-action spring, rear shifting is practically effortless and always super smooth. The top pulley stays a uniform distance from each cassette cog ensuring that every shift resonates with the plunk of exact gear engagement.

Chain-wrap capacity: 39 teeth

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: 53/42 chainrings and a 12-23 cassette: (53 – 42 = 11) + (23 – 12 = 11) = 22-tooth chain-wrap capacity.

Maximum cog size: 32 teeth

Cassette compatibility: 10-speed cassettes
