Compact Chainset

mwooldridge

With my current bike (which is now 4 years old) I decided that for my day to day cycling I really did not need a triple and double would be fine. I am now looking to do a couple of sportives; particularly Bealach Mor and Ullapool and so am considering upgrading to a compact setup.

A few years ago, before compact chainsets, you selected the type of rear mech based on the sum of the difference in teeth between largest and smallest cogs on chainset and cassette. Looking through the Shimano website the compatibility charts mention nothing about this calculation and purely say the ss rear mech is for doubles and the gs rear mech is for triples. Am I therefore right in assuming that if I go for a compact chainset I need double front and rear mechs (i.e. FC7650, FD6700, RD-6700, CS-6700 11-25)?

Thanks,

Mike

If you have a standard double fitted now, your existing derailleurs should be absolutely fine with a compact.

I swapped to a compact on one of my bikes last year, no need to swap the derailleurs or cassette, you just drop your front mech slightly,
i did swap the cassette for an 11/23 and after spending near on 20yrs using a standard chainset this seemed to give me just that little bit more on the hills..

Thanks for the feedback guys. Always nice to confirm before finding I need something else and I get wife rage. :shock:
