Crankset/Cassette Compatibility?
Will an Ultegra 53-39T, 11 spd crank work with a Shimano 8-spd cassette? We're keeping the same Shimano FD. My friend's bike has an off-name cheap square-drive crankset and BB that's being replaced with the aforementioned crankset, external threaded BB, and new 8-spd chain. Thanks for your help!

It should work fine. Shimano 11 speed doubles actually have more space between the chainrings (7.9mm) than their 8 speed doubles (7.6 - 7.7mm). I've had smoother shifting using a 9 speed chain on mixed drivetrains with 8 speed cassettes.

Agree, you should not have any problem as the chainring teeth have the same dimensions because the chains have the same inside dimension but if you have got a caliper you can double check.

Is that smoother shifting on the FD or RD or both using the 9 speed chain?
