Dear forum

Apparently I've been posting on an inappropriate section of the forum ....however pursuant to advice from those who have more experience here I shall further try my luck for some constructive advice here.........Please.

New bike ordered & coming ..and have the opportunity to amend the front chain wheel setup, as I live in mountains (alps) have already decided triple over compact, however am looking at 170 mm "arm" and probably 52/39/30 standard rings.

I have briefly viewed the Shimano tech site and nothing jumps out at me ...BUT what is the difference between the FC6603 and FC6703 save perhaps some degree of interchangeability ...maybe I am missing something???

Salutations :shock:

    6703 is simply the newer version of the triple chainset.

    Most kind for the response, however newer version often includes some improvement ..or otherwise..any idea what's changed other than colours?

    In a nutshell, the 6700 chainset is stiffer, lighter and shifts slightly better due to the stiffer, hollow outer ring.

    The 6700 looks miles better too.

    I must agree it certainly does look much better aesthetically but needed more detail in respect of performance...thank you for the information, that's about what I needed :)

    How tall are you? Do you prefer higher or lower cadence to conquer those Alps of yours?
    my isetta is a 300cc bike

    Not been on site for a while ...alligators...up to arm pits....

    I'm bit on short side 5'9 ...tend to grind it out rather than shifting down
