  1. After lusting for a carbon crankset for a while I finally
    broke down and bought the FSA Compact Carbon. I got mine
    from Dave Lettieri at FasTrack Bicycles.

    Installation

    Very straightforward. It is replacing a Campy Record 39/53.
    FSA doesn't offer a Campy tapered version so I also had to
    get an ISIS bottom bracket to go with it. Dave recommended
    the Platinum (Cro-Moly) version because he thinks it is
    stiffer and more durable. It seems like a decent enough
    bottom bracket but wish I could have left the Record one on.
    FSA included installation instructions with the kit but no
    torque spec's. I was able to download them from the web site
    though. I also had to lower the front derailleur a bit due
    to the smaller chain ring plus readjust it a bit.

    Riding

    I was getting some creaking at first. I was very careful
    during installation to do things according to directions. I
    used anti seize on the cup threads and Phil grease on the
    ISIS spindles. After a couple of rides however this went
    away. If these really are stiffer than my record crankset I
    can't tell. I have ridden this with an 11-23 and 12-25. I
    used the 12-25 to go up a very difficult climb outside of
    Davis, CA where I live called Mix Canyon Road. The last mile
    exceeds 20% grade. The 34-25 helped a lot getting up this
    thing. I had planned to use the 11-23 most of the time with
    the exception of really steep climbs but may just leave the
    12-25 on unless I find myself missing the
    11. While the lower gears of the 34 are noticeable, I had a
    hard time noticing a difference between the 50 vs.53
    tooth big ring. It took me a little while to get used
    to the bigger jump between chainrings when anticipating
    shifts but am getting used to it. The front derailleur
    is working noticeably harder to go from the 34 to the
    50 but handles it reasonably well. If you are upgrading
    to this from a triple you may want to just leave your
    triple front derailleur on.

    Summary

    So far my feelings are a little mixed. It looks great and
    greater gear range is nice, but the shifting isn't quite as
    good as the 39/53, and front shifts for me feel more awkward
    due to the greater change in chainrings. If you are already
    running Campy 10 speed like me you can get about the same
    range I'm getting with the 12-25 by using the 13-29 cassette
    with a 39/53--and for a lot less money. Of course you could
    go really low with this thing and use a 13-29 cassette. It
    would give you about the same low gear as a 30-25 without
    having to use an ego-crushing triple crankset, but if you
    need gears that low my recommendation is get the triple.

    Mark,

    Thanks for the report. Mine is due in at the bike shop on
    Friday. I hadn't thought about having to lower the
    drailleur. Makes sense, though. I'm gonna use mine with a
    12x27 cassette.

    Another less expensive way to go is to keep the standard
    front chainrings, throw on a mtb rear derailleur and you can
    get up to a 32t rear cassette. That'll take you up a wall
    with a 38 or 39t front ring.

    Mark's Campy double front derailleur will shift the 50/34
    FSA chainrings better than anything Shimano has. If your
    front derailleur is STI indexed, a DA front will work best.

    We set up a TREK Madone with an FSA 50/34 with Shimano 10-
    speed DuraAce the other day, and it worked, by all accounts,
    fantastic. Everyone here was blown away with how nicely it
    performed. Definitely in the future for my own bike...

    For me the benefit of a compact setup is not having to front-
    shift to find a comfortable gear. With a 48/36 and a 12-27
    10spd cassette I can maintain a comfortable cadence in the
    big ring for anything between 12 to 35mph, so I just stay in
    the big ring most of the time.

    Funny, but I just put mine on last week. I rode it 40 miles
    the first time and 75 miles today. I LOVE it! I put on a
    Record 12-23 in the back and it shifts just great. I also
    got the platinum ti isis bb, and the only issue I had was
    due to my short chainstays. The chain line isn't perfect,
    but I get no rubbing in any gear and it shifts great. I went
    from a 39/52 13x26, which didn't have a big enough top gear.
    The FSA setup gives me a bigger top gear, smaller low gear,
    and much better steps along the way, with only one crossover
    and NO duplicate gears!

    Cat who couldn't be happier ;

  7. Why not use 48-34 instead? That's exactly the same tooth
    difference as 53-39. And TA make a really nice matched
    pair of lightweight chainrings in that size - see --

    44 for a photo.

    Once you find the best front derailleur, the FSA big ring is
    the best I've used for this application. It doesn't care
    what crankarm is holding it. Neither the Stronglight nor
    Vuelta SE rings work as well.

    I have an XTR 900 front derailleur, which was made for rings
    of this size, that works marvelously but it it's a triple
    derailleur. I doubt it is STI compatible.

    I happen to have the FSA on one bike like yours but any 110
    bolt pattern crank works fine and costs much less. My wife
    runs a Sugino XD, my tandem an old Specialized, and my CAAD4
    a Stronglight Granfundo. I looked through a box of old
    cranks at a local shop and found a Ritchey Logic/$20 and
    Sugino GT/$10. The conversion to 50/34 need not be costly.
    48/34 and 52/36 are nice too.

    I guess "costly" is a matter of degrees. And I happen to be

    Well, it's not that big a difference. Plus a 50/12 is still
    a big gear. In fact a 48/12 is big enough for most people --
    identical to the 53/13 top (4:1) which has been a standard
    for many years.

    The main reason to have a 50-53T ring is to be able to use a
    13t cog. Drivetrain friction increases as cogs get smaller,
    and the ramp-up is quick below 14T. Smaller cogs were the
    product of a misguided attempt to save weight. I bet the
    drivetrain friction matters more.

    34-48T rings would have the same 14T gap as a
    traditional 39-53T setup, and with a 12t cog you'd still
    have a 4:1 top gear.

    a 13-29 cassette. It would give you about the same low
    gear as a 30-25 without having to use an ego-crushing
    triple crankset, but if you need gears that low my
    recommendation is get the triple.

    I see nothing ego-crushing about a triple. I often gear down
    and spin right past people who are trying to stomp up a big
    hill in a 39/25. Plus I can shift between inner and middle
    rings, and alternate between sitting and standing. At the
    other end, the 42-52T shift is more usable because of the
    smaller gap. So when I need a bigger shift, I just use the
    front, and when I want a little one, I use the rear. I use
    both almost equally, while other riders seem locked into the
    idea of two distinct ranges. To me there's no downside
    whatsoever to a triple -- it's all pluses.

    Wide-double cranks do have a great niche -- improving
    gearing on older STI double-ring bikes, where converting to
    a triple is cost-prohibitive. Of course the FSA isn't cheap,
    but a 110/74 BCD Sugino with 34-48 rings could be a great
    problem solver, for example. If I acquired a 10-15 year old
    bike with a double, this is exactly what I'd do.

    Otherwise, just get a triple.

    Because the "image" of a $5000 Trek Madone, the Lance bike,
    with a triple does not work. Ego and image are very strong
    and over ride logic.

    And because DA10 doesn't come in a triple. I've thought though that the next modification to the DA crank (FC7803) will take the "not cut-out" look to the extreme and will have a fully solid-looking face so other riders won't be able to tell how many chainrings are on the inside. What a marketing coup de grace that would be - you could have a bike with a crank that *looked* like Lance's (or Jan's or Iban's) but that functioned more like what a middle-aged guy with fragile knees really needs (thinking of myself here, not Mike... for whom a compact carbon crank would certainly be a more astute selection).

    See you at Primavera next week!
