SRAM’s latest mountain bike drivetrain cranks the volume past 11 all the way to 12 — because 12 is one more than 11 and more is always better, right? Not so fast, jive turkey. Long before SRAM launched its 12-speed Eagle drivetrain, Shimano was equipping 10-speeds with its own Eagle derailleurs.
Here’s how these two components that would never, ever, be bolted to the same bicycle stack up against each other in BikeRadar’s bird battle royale!
In comparing these two derailleurs, it’s amazing how little the rear derailleur has changed in forty years.
SRAM and Shimano Eagle derailleurs share many of the same features, including barrel adjusters to fine-tune cable tension, limit screws to control the range of movement, B-tension screws to adjust the orientation of the derailleur cage in relation to the freewheel/cassette, and a pair of jockey wheels through which the chain travels.
There are, of course, some striking differences.
SRAM Eagle builds on the success of SRAM’s clutch-equipped Type II derailleurs with a “Type 3” clutch that is said to be stronger as well as smoother.
