Triple to Compact 50/34 12-25

I may "fingers" crossed be getting my new bike tomorrow.

It looks like it could be a 50/34 with a 12/25 cassette. I currently ride a triple set up and just wondered how much of a jump will this be, especially on hills. It's a Campag so that rules out a 12-27 set-up

    you can work out what the gears will be like, but seeing as your in london I really don't think you will have to much trouble

    Get a 13-29 cassette then. I've got 50-34 with 13-29 on my winter bike and I can't see that I really miss a 11t or 12t on clubruns and solo rides, I easily pedal to 40mph with 50-13.

    Good call on the Campag, BTW.

    Fingers crossed they still have the bike available tomorrow.

    The only problem I think you'll have is the large jump between the 50 and 34-you can get used to it, but to have to up/down shift 2 or three cogs at the back is a bore

    You'll find it easier to change chainrings when you are changing between the 17 and 21 at the back-limiting the jump to around 10 gear inches (50/21=64", 34/17=54".......and 50/17 is 79" if you just changed chainrings at the 17, middle rear sprocket)

    I have 48 and 34 chainrings on one bike, with 12-28 at the back (it's a cross bike) and 50-36 on another, with 13-26 at the back-and I have the 13-29 cassette when required
    [, I easily pedal to 40mph with 50-13.

    Good call on the Campag, BTW.

    That'll be a cadence of around 130!

    I have never been dropped on a sportive through lack of a high gear-I concede if you're racing, you might want to have a higher one. Even so 50/13=104", which is higher than Coppi even had, and as much as Merckx used, I believe

    My problem is getting an "engine" with high enough power for the climbs :)

    be careful with the 13-29 - make sure you have clearance to fit the 13 tooth cog without the chain fouling the seatstays!

    Don't look for possible issues, just ride it. Blimey, it's A NEW BIKE, you're supposed to be excited!

    Where's that "popping champagne cork" mp3 file when I need it?

    If you find the gears aren't low enough then go back to the shop and discuss it later.
    Aspire not to have more, but to be more.

    It's doable, I'm not sure I could sustain 130rpm, but once I reach 40mph, I normally don't bother pedalling anyway...

    Hell NO. That is pure sex (i like it anyway)

    I went to have a look at a Wilier Mortirolo Veloce 08 that was on special offer.

    i quite like the mortirolo - but the white paint job doesn't do it any favours in my opinion

    not f.ugly though!

    Rather liked the '07 and '08 colour options on the Mortirolo.

    I think the Barolo must've been flowing for a good few hours when they agreed the 2009 paint jobs though. :shock: :x

    it was black
  • ive just gone to a 50/34 compact and to be honest i aint impressed.to big a change between the 50 and 34.in my opinion it is also a clunky gear change according to my lbs it is because of the size of spring inside the STI lever. i'd rather 53/39 or 52/42

    i do find, there is a fair jump and there is a point where your running inbetween the rings. the shifting i can't comment on as i still use the fricton only suntour shifter up front.

    this said i love the range it gives.
