Standard or compact crank for IMWI???

What are the recommendations for IMWI crankset?   Compact?  I'd ask Strauss, but he told me no questions while he's riding :-)

Most of my races have been ridden with a compact.  However, I am looking at a new tri bike, and that Scott has my eye, but a compact crank is incompatible with the Scott Plasma 3.  Bizarre.

Thanks

    Compact, all the time - ESPECIALLY on a hilly course. 50/34 compact with at least a 12x27 cassette will do great.

    Interesting, why is a compact crank incompatible with a Plasma 3? First I've heard of that and am very currious why. Some older cervelos had FD hangers that were mounted a little too high for a compact, but a SRAM or FSA FD solved that problem. Other than that I have not hear of bikes that would not fit a compact.

    To your original question, unless you are riding under 5 hours at IMWI (which only about 15 people do each year), I highly recomend the compact.

    Barry, I'm riding compact and 25-12 at IMWI. FYI, the steepest hill is about 7-8% for about .25mi. Same grade but shorter than Salvia Canyon. There's 2 more hills, about a half mile each, at 6%. Chantry is 6%.

    As Matt said, the derailuer hanger on my P3C wouldn't accommodate the compact but I fixed that by using a SRAM FD, with two positions.

    FWIW, my 2007 P3C hung a Shimano crank just fine. Not sure if you're currently on the cervelo (hence the remarks), nor how old yours is if so.

    Thanks everyone.  Compact it is.  Here is that comment about the Scott Plasma 3 that I've seen in few places.  From All3Sports:

     

    3 - Be advised that the new Plasma 3 WILL NOT work with a Compact Crank! The Chainstay mounted brakes will come in contact with the Front Derailleur Cage, rendering it inoperable.

    I could see that, basically the FD can't be positioned low enough because of where they put the rear brake.  I know first version of the Felt DA that had the brake on top of the chainstay had clerance issues if you did not use a certain brake, therefore I wonder if there is a lower profile brake you could put back their that would allow the compact.

     

    In this case seeing the bike at a LBS is ver valuable so you can see how much room there is down there.
