  1. I would like to make hill climbing a little easier, and have to decide
    between a Campagnolo Centaur triple front crank or a compact crank.

    If I purchase a triple, will I need to purchase a new brake/shifter combo as
    well? I was told this at the bike shop, and wanted to confirm this.

    Any other ideas on the compact vs. triple debate?

    All Campy shifters are compatible with doubles or triples. No need to
    replace them.

    Wow. I guess truth is stranger than fiction. I could not even dream
    up such an incompetent bike shop. I strongly advise you to never go
    into that pathetic shop again. Advise everyone you know to never go
    there. Organize a campaign to drive such a blight on the world out of
    business. Sure glad I don't live in Canada if awful bike shops like
    this are able to stay in business.

    Do the math. A compact Camapgnolo Centaur comes with a 34 tooth inner
    chainring. You can get a 13-29 10 speed cassette. Or a 14-28 or
    13-28 9 speed cassette. 34x29 is 31 gear inches. 34x28 is 32 gear
    inches. For $50 or more USA dollars you can buy a 33 tooth chainring
    from TA Specialties to fit your 110 mm bcd Centaur compact. 33x29 is
    30 gear inches. Not sure its really worth $50 or more to get 1" lower
    gear, but it is an option.

    What gearing are you currently using? Do the math and figure how low
    of a gear you have now? How does it compare to the above? Can you
    put on a 13-29 or 13-28 cassette instead if you are using a 12-25 or
    13-26 now? Much easier and cheaper way to get a little lower gears.
    How much lower of a low gear do you need? Just 1 lower gear would do
    it? Or do you really want much lower gears than you currently have?

    Going to a triple requires new crank, new bottom bracket (although
    with the modern integrated things the BB is just part of the crank so
    you get one automatically), new long cage rear derailleur, new triple
    front derailleur. You can use a double front to shift a triple and a
    short cage rear derailleur, but for best shifting and the ability to
    use all gears, you need the triple derailleurs. Cost adds up. And of
    course maybe a new bigger cassette. And always a new chain.

    Going to a compact may be lower cost. New crank (with its integrated
    BB?) may be all you need. Short cage rear derailleur will handle
    shifting and chain wrap just fine. Double front derailleur may or may
    not handle shifting just fine. Front derailleurs are really cheap so
    not a big deal to get a triple or compact specific to shift the
    compact crankset. And maybe new bigger cassette as above. And always
    a new chain.

    Shifting can be a nuisance with the compact. You may end up with the
    changeover between the big and small rings exactly in the range where
    you spend most of your riding time.

    If you really want low gears, you have to spend the money and get a
    triple. With a triple you can easily and cheaply (less than $10)
    replace the standard 30 tooth 74mm bcd inner chainring with a 28 or 26
    or 24 tooth and get very low gears. And because you are using quality
    Campagnolo shifters, they will handle a 52-42-24 perfectly. It would
    be a shame to spend the money on a compact and not have low enough
    gears when you are done and spend the money again on the triple to get
    the low gears you want. Or be stubborn and ruin your knees climbing
    hills in the not low enough compact gears.

    I have a Centaur triple and it works great. I find that in my area,
    with mostly gently rolling terrain, for 90%+ of my riding, I can keep
    the chain on the 42 tooth middle ring, which means I only am shifting
    rear cogs. I mostly use it like a double; the small ring is used very
    rarely for a bailout gear. The shifting is precise; as good as any
    double I've owned.

    If I had a compact double, I'd be constantly going back and forth
    between the chainrings to find the right gear. If I were riding in
    different terrain, I might come to a different conclusion, but for my
    needs, the triple is perfect.

    --------
    kind of went thru the same thing, but with shimano, you have to get a new
    rear derraileur (long cage) if you go from a double to a triple. I don't
    know enough about campy to know if you have to do that too. No experience
    with compacts, but I know a couple people who wished they'd gone the triple
    route, after they installed compacts. It all depends on how strong your
    knees are.

    Triple no doubt about it. Wider range, a useful middle ring and you can
    use a close ratio cassette.

    Here's a vote for compact. I use a Record 34/50 with a med cage rear
    der. With the 50 and a 13 tooth small cog I spin out at about 35 mph
    (on the flats with a tailwind). Good enough for me. But if I put
    the 13 - 29 cogset on, I get a low essentially equal to a 30/26. IF
    you are planning to tour or do long mountain rides or are less strong
    as a climber, go for the triple. But for all other riding, I like the
    compact. When you get down to it, though, I have four cassettes that
    I ride: a 11 - 23, 12 - 25, 13 - 26, and a 13 -29. Leave the 13 - 26
    on for almost all riding.

    Essentially, the difference is whether you want to carry all your gear
    ratios on your bike, or whether you want to have them in cassettes in
    your parts bin.

    With a triple put on a 13-26 (13-14-15-16-17-18-19-21-23-26) cassette

    The compact requires certain additional skills, tools and behaviors
    but on the other hand, offers many benefits over the current 53/39 de
    facto standard without having to go through the hassle and cost of the
    conversion (fder, rder, chain, crank). And if he didn't have campy,
    it would be MUCH more expensive. With the compact, all the guy has to
    do is get the crank, lower his fder, shorten the chain a bit and
    ride. And if you rotate two chains, and don't let them get over 2000
    miles or so, skipping is not a differentiating issue between compact/
    triple no matter how many cassettes you run.

    And if he has a known terrain that he always rides in, one cassette
    will do (13-26 is probably appropriate for all but the most
    mountainous non-touring terrain).

    So the compact is cheaper and easier to convert to, and with the
    proper choice of cassette is as good as a triple. And one additional
    cassette will fill out any desired gear range.

    An easy, cheaper choice, IMO.

    knees are.

    There were docs on the Campy site that gave details about what you
    need for short vs. medium vs. long cages, but that info is either
    moved or removed. Anyway, I couldn't find it just now.

    But my three 53-42-30 campy triple drivetrains (Record/Chorus/Centaur)
    from 04-06 all have medium cage RD. So long as I keep the big cog
    less than I think it's 27, which is fine, there's no need for long,
    and you don't want long unless you have to do it. With the triple you
    have no need for big cogs. In fact one of the big advantages of
    triple is keeping the cassette sprockets mostly consecutive,
    e.g. 11-23 for less than steep mtns, 12-25 for steep mtn's when I'm
    sore or in recovery, and 13-26 for cx, when you infrequently need the
    11 or 12 sprockets. And you can shift to and use any gear with these
    setups.

    Aha, you want the cheapest solution. Hmm, you choose a Record CT crank
    and 4 cassette's??
    I have one bike with a triple and one bike with a Record Compact. I have
    no problem to admit that the compact on that bike is for the looks and
    the weight. Gearwise the triple wins all the time.

    I wonder if D'oh Boy has ever figured the cost of having four 10 speed
    cassettes lying around? At the normal retail price of 10 speed Veloce
    cassettes, he has $300 tied up in cassettes. All to get the same
    range he would get with a triple crankset.

    I think Campagnolo triples come with 53-42-30 rings now. And of
    course a new 24 tooth 74mm bcd ring is $5 on sale or $10 full price.
    Easy and cheap way to get infrequently used low gears. Take the 13-26
    cassette. 53x13=108". 30x26=31". With the 50-34 compact you need a
    50x12=110" and 34x29=31". I'm sure you can cobble up a 12-29 cassette
    and end up with big gaps in the gears making for awful shifting. Lets
    say you have a goofy desire for taller gears and use the 12-25
    cassette instead of the 13-26. 53x12=127". 30x25=32". With a
    compact you need 50x11=120" and 34x29=31". I guess you could cobble
    up a 11-29 cassette and end up with huge gaps in the gears making
    really terrible shifting. Now lets say you spend $5 and put a 24
    tooth inner ring on your triple and want super high gears too.
    53x11=128". 24x23=28". With a compact you get 50x11=120" and
    34x29=31".

    But it is stylish to have a compact crank. No style with a triple.
    Just function.

    If you aren't one who is slightly embarassed by having a 39 instead of a 42
    or 44, and you're sincerely asking about compact versus triple, it's
    probably time for the triple and some reall sissy gears.

    Here's a vote for compact. I use a Record 34/50 with a med cage rear
    der. With the 50 and a 13 tooth small cog I spin out at about 35 mph
    (on the flats with a tailwind). Good enough for me.

    Why settle for 'good enough'?

    I think that's a philosophical question, but I'll take a stab. I want
    to spend very little time mucking about with my commuter bike. As long
    as the gearing is close enough to what I need, I'm happy. I'm not
    searching for a theoretical 'perfect' setup.

    What does a compact have what a triple doesn't gearwise?

    Better shifting? At least, that's been my experience.

    I run a 48/36 x 11-28 [1]. That gives me about the same range as a triple
    using a 52/42/30 x 12-25 [2]. A 34 lower ring would drop me to 32.5 gear
    inches as my lower. Of course, if you're touring or a similar
    application, the triple is eminently sensible.

    [1] 34 - 116 gear inches
    [2] 32 - 116 gear inches

    I would like to make hill climbing a little easier, and have to decide

    If I purchase a triple, will I need to purchase a new brake/shifter combo as
    well? I was told this at the bike shop, and wanted to confirm this.

    Pay close attention: If you have Ergo, and the shop told you that, do
    not go back to that shop.

    They are trying to rip you off. Now, if you are talking about 2007
    model shifters, some things have changed in the front (it is apparently
    really indexed now), but anything older will shift any derailleur, over
    two or three chainrings, no problem. You may have trouble with a quad,
    but not a triple. Since you are talking about changing things, I would
    bet your bike is at least a year old.

    If you plan on loaded touring, definitely get a triple. Otherwise, a
    compact double will be good, IMO.

    You may need a longer cage rear derailleur, but that is a fraction of
    the cost of the shifters. You will be told you need a new front
    derailleur, but I have a super-compact front, which I use as either
    double or triple depending on what I plan. This is with a mid-80's
    Record derailleur.

    As others have said, you can usually change to a compact double without
    any other new parts, and get most of the benefit of the triple.

    But my three 53-42-30 campy triple drivetrains (Record/Chorus/Centaur)
    from 04-06 all have medium cage RD. So long as I keep the big cog
    less than I think it's 27, which is fine, there's no need for long,
    and you don't want long unless you have to do it. With the triple you
    have no need for big cogs. In fact one of the big advantages of
    triple is keeping the cassette sprockets mostly consecutive,
    e.g. 11-23 for less than steep mtns, 12-25 for steep mtn's when I'm
    sore or in recovery, and 13-26 for cx, when you infrequently need the
    11 or 12 sprockets. And you can shift to and use any gear with these
    setups.

    Yes, you don't need big cogs, I've never needed anything bigger than a 25.
    The drawback is shifting a double is more fun, in my opinion, than the
    complicated triple. It seems to me, that you shift a lot less on a double.

    Wow. I guess truth is stranger than fiction. I could not even dream

    Yeah, stupid shop! Never mind the fact that we have no idea what kind
    of shifters he's using (i.e., the shop could be right), or that we
    weren't there and have no idea what the context of that assertion
    was. We here at r.b.t. know better than any shop!

    Seriously, do you know what's even worse than misinformed shops? Know-

    Do the math. A compact Camapgnolo Centaur comes with a 34 tooth inner
    chainring. You can get a 13-29 10 speed cassette. Or a 14-28 or
    13-28 9 speed cassette. 34x29 is 31 gear inches. 34x28 is 32 gear
    inches. For $50 or more USA dollars you can buy a 33 tooth chainring
    from TA Specialties to fit your 110 mm bcd Centaur compact. 33x29 is
    30 gear inches. Not sure its really worth $50 or more to get 1" lower
    gear, but it is an option.

    What gearing are you currently using? Do the math and figure how low
    of a gear you have now? How does it compare to the above? Can you
    put on a 13-29 or 13-28 cassette instead if you are using a 12-25 or
    13-26 now? Much easier and cheaper way to get a little lower gears.
    How much lower of a low gear do you need? Just 1 lower gear would do
    it? Or do you really want much lower gears than you currently have?

    Going to a triple requires new crank, new bottom bracket (although
    with the modern integrated things the BB is just part of the crank so
    you get one automatically), new long cage rear derailleur, new triple
    front derailleur. You can use a double front to shift a triple and a
    short cage rear derailleur, but for best shifting and the ability to
    use all gears, you need the triple derailleurs. Cost adds up. And of
    course maybe a new bigger cassette. And always a new chain.

    Going to a compact may be lower cost. New crank (with its integrated
    BB?) may be all you need. Short cage rear derailleur will handle
    shifting and chain wrap just fine. Double front derailleur may or may
    not handle shifting just fine. Front derailleurs are really cheap so
    not a big deal to get a triple or compact specific to shift the
    compact crankset. And maybe new bigger cassette as above. And always
    a new chain.

    Shifting can be a nuisance with the compact. You may end up with the
    changeover between the big and small rings exactly in the range where
    you spend most of your riding time.

    If you really want low gears, you have to spend the money and get a
    triple. With a triple you can easily and cheaply (less than $10)
    replace the standard 30 tooth 74mm bcd inner chainring with a 28 or 26
    or 24 tooth and get very low gears. And because you are using quality
    Campagnolo shifters, they will handle a 52-42-24 perfectly. It would
    be a shame to spend the money on a compact and not have low enough
    gears when you are done and spend the money again on the triple to get
    the low gears you want. Or be stubborn and ruin your knees climbing
    hills in the not low enough compact gears.

    If you have Ergo's already no need foor new shifters.

    Triple no doubt about it. Wider range, a useful middle ring and you can
    use a close ratio cassette.

    What does a compact have what a triple doesn't gearwise?

    Gearwise, the advantage always goes to a well-chosen triple.

    Image-wise, the compact double looks more 'macho' ; that's a big part
    of the appeal, IMO.

    The nice thing about a double as opposed to a triple is that it
    requires less thought -- it's binary. You just shif up or down all
    the way. If you're riding in situations where you have to shift
    quickly, this is nice. If you're just cruising leisurely (even fast,
    but mentally leisurely) it's no real advantage.

    Of course Ozark has some sort of insecurities where he often has to
    claim other people do things for "image" reasons.

    I don't think this phenomenon is limited to bike shops. It's one of the
    perils of working retail I imagine.

    S'okay. I'll elide the counter-rant about being the poor customer stuck
    with a crappy bike shop with clueless staff. Thankfully I live in
    Seattle and have a good selection. I still do just about everything
    myself since I'm cheap and impatient.
