Campagnolo Athena Rear Derailleur
$206.99 - $210.00
Details
Campagnolo's Athena Rear Derailleur uses an advanced-parallelogram design that assures quick, precise shifting. The aluminum construction keeps weight low and boosts strength for a rigid assembly. Plus, the pulleys are made from a special material for quieter drivetrain action.
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.
Largest cog this derailleur can handle: 29 tooth
