mixing chain rings
I want to put a 39t round inner ring on my oval biopace crank set.The bcd is identical.Is that acceptable?Can I expect any problems?The original ring is 42t and I could use the help on the hills.

In the days when oval/biopace rings were common it wasn't unusual to find them that way from the factory. I still have a Sun Tour labled crank that ismoval, oval, round on the big ring and have put together sets will mixed rings without problems. Roger

Ive never had a problem when replacing biopace with a normal chainring.
