Campag and Compacts - 52-36 or 50-34?

edited September 2012 in Road buying advice
Am contemplating a road bike and the dealer is advising me to go compact.

I'm not a racer (so don't probably warrant the 52/53), nor will I be doing the Gotthard pass (so don't need massive hill-climbing), but I'm in a bit of a quandary as to whether to go for the 50-34 or the 52-36 that I gather is available in the compact?

In term of sprockets, I'm looking at 11-25 as i would prefer longish-legged gearing.

What are your views and advice?

Thanks!

    If you are not racing then a 50x11 is plenty fast enough.
    If you go for the 52 then a 12 at the small end would do.
    I find a 34x25 is fine for climbing but needs effort and out of the saddle on anything steeper than 12% and if you go for a 36 then I would recommend a 27 at the back.

    The biggest problem with compacts is the gap between the big & small ring. It can be circumvented by changing at the back at the same time.

    If I was buying from scratch today I would try for a 50/36 & 11/27 but I don't think this set up is available off the shelf.
    None of the above should be taken seriously, and certainly not personally.

    It all depends on how fit you are and the terrain you will ride on. If you live in a hilly region (like the SouthWest, Wales, Pennines etc.) then 50-34 might be best. I was using 53-39 in Hampshire, but when I moved to the Tamar valley area, had to change over to compact 50-34 to be able to climb some of the local hills (30% and more).

    I use a 11/25 cassette on my fast bike, but that limits some the hills I can climb. I use a 12/29 cassette on my do-it-all bike.
    Ultimately, if you do not need to climb >25%, then 52-36 will be ok with a 12/29 cassette. Bit more than 25%, you might be better on 50/32. Then again, if you've got the strength....

    I usually use 50/36 with 12-25 or 13-26 but am going to over to 48/36 since I very rarely get into 50 x 12/13 and Campag are doing a 12-27 10 speed cassette

    Just wondered where you read that Campag are doing a 12-27 10 speed, afaik they only do 13/26 or 13/29 for 10 speed, 12/27 & 12/29 are available in 11 speed
  • I don't mind having a bottom gear that I may only use once in a blue moon, but I hate having a top gear that I'll rarely use. My road bike has a 50/34 compact with a 12-30 cassette. I've yet to use the 50x12 top gear. Thinking of replacing the 50t chainring with a 48t or even a 46t. If I should be lucky enough to be spinning out at 30+mph then I'll just freewheel.
    Note: I'm 61 and can't push big gears anymore... :)
    I'm not getting old... I'm just using lower gears......

    I read somewhere that 12-27 10 speed was coming but I don't think (?) it's available yet. Also a 12-30 IIRC.

    See, that's what I'm talking about. My fixed is 48x19 (or 18) and I can maintain 20+ mph and get up a lot of climbs and my commute mtb has 46/36 with 12-23 and I've never been on the bottom gear and v.rarely on the top one and I can get about fairly quick. Different if I was competing but for goofing about a usable range of gears works better
