Change 105 8spdCranks w/chainrings to 9spdUltegra FC6500 w/chanrings-Any chain issues
Ok here's the deal.
I have 105 8spd cranks---#1056 Double
I am still using the 8spd HG-90 rear cassette out back with both the 8spd deraiileurs and an SRAM PC58 chain.
Can I swap to Ultegra 9spd cranks(#FC 6500 Double) and chainrings without any chain tracking problems?
I was told there may be a problem because the spacing between the chainrings is smaller on the 9spd and may cause a tracking issue there.
The guys at the bike shops have told me there shouldn't be any problems, but I'm just not sure.
I'd like more input on this. I also looked at Shimano's compatibility chart but couldn't find anything on it.
To me that would suggest that they don't want you to do it.
What's up???
