Campagnolo setup

HI,

I just acquired a 2012 Wilier Izoard with a 10 speed campagnolo record groupset: 53/39 and 11/25.
The reason I got the bike was its price....
I'd like to change it for an easier ride since I am not as fit as I used to, and I live in a hilly part of Scotland.
The bike rolls on Campagnolo shamals.
What would be the cheapest and smoothest option? 12/30 or 13/29 at the back? Or change the Cranks: 175 mm (Record Carbon) 39-53 at the moment.

Thank you in advance.

    I think you'll find the rear mech wont take a cassette bigger that 28-29 only the newer models can go 30+ your best bet is a 29T cassette and swap the chainset for a 50/34T
    Rule #5 // Harden The censored Up.
    Rule #9 // If you are out riding in bad weather, it means you are a badass. Period.
    Rule #12 // The correct number of bikes to own is n+1.
    Rule #42 // A bike race shall never be preceded with a swim and/or followed by a run.

    Cassette is cheaper than cranks and generally more effective at reducing gear ratios. If you gain 5 teeth at the back, it's like losing 7-8 at the front on the easiest gear... and at the front you can only lose 5.

    I have 2015 Athena and it works fine with a 30 tooth Shimano cassette on my turbo.
    29 max is recommended but 30 works. Cheapest option would be a 29 or 30 cassette. Best would be a combination of that and a compact chainset. Said as someone who has that setup. 😉
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    Thank you both, I will look into changing the cassette to a 13/29T first and give it a try.
    I'd really like to avoid changing the crankset... But if I have to i will.
    Is it reasonable to try and change the inside ring only or would that cause too much stress on the chain and make it jump?
  • pblakeneypblakeney Posts: 24,685
    I think changing the inner ring would be too big a gap and I doubt you'll get a smaller one to fit anyway.

    I run a 12-30 Campag cassette on a 2012 Chorus mech and it works fine, and I don't think you can go smaller than 38 on the chain-set.

    ok, i guess i'll try oth a 12/30 and 13/29 and see how it goes.

    thanks a lot everybody

    Is there a 30 tooth 10 speed cassette for Campag? I don't think Miche even made one (I may be wrong).

    I didn't think there was one either and had to have a look in the spare parts catalogue - the 2013 catalogue has a Centaur 10sp with 24/27/30 cluster. So they were made, however, I suspect actually finding one will be the challenge.

    Miche also make a 30 tooth one in their Supertype range so this would be the OP's best bet if a 30 tooth is required.

    Also worth noting is that the BCD of the 39/53 chainsets is different to the 34/36 50/52 so you would likely need a third party inner ring if that's all you were changing and the shift will probably not be as crisp.

    I have one so it certainly does exist, probably hard to come by now though, have a look at thecycleclinic page, you can make up a Miche one in whatever ratios you want for about 60 quid.

    drop the chainrings to 50/38 from TA or stronglight (do not lose the hidden bolt if its a 5 arm set) and go to 13/29. You might get away with a 30 cog but you would have to try it
