Oval chain rings for ultegra spider
Postby big booty » Fri Nov 24, 2017 11:16 am
Does anyone make oval chain rings for an ultegra crank? Having cycled most of my life with the old shimano biopace Ive upgraded to a new bike with an ultegra crankset. Properly set up the old biopace (they got the indexing wrong when they introduced it in the 80s) provides a far superior pedalling stroke so Im want to see if its possible to buy oval chain rings. Not wanting to replace the whole crankset, just the chain ring.

Edit: sounds like they're a bit different to Biopace, but see how you go.
