Afternoon people,
Need to replace the chain-rings on a 7400 series crankset - inner one is worn, outer has a broken tooth. Bit of conflicting info out there on the www - velobase says 130BCD which was my original thought, but when double-checking i've seen comments about 135BCD? Anyone able to confirm which is correct please?
Also, I'm assuming I can only go 53-42 so that the set up isn't compromised?
And finally - I want black chain-rings - any knowledge of brands / retailers that will fit the bill?
Many thanks...
