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.
