    If in doubt, I'd go with Shimano. That way, if you have shifting issues afterward, you'll KNOW that the problem has to be something other than the crankset or chainrings.

    I have no experience with external BBs, but I am thinking that, in the long run, they're probably not good value.

    The 105 is square taper?

    I don't know how they are going to play out in the future but EVERYBODY has switched to external bearing bottom brackets, including Campy which is usually very conservative. I expect there are no major or inherent weaknesses or the word would have certainly gotten out by now.

    The 105 could be a square taper or Octalink.

    New 10 speed 105 is octalink with external bearings. The same design and bottom bracket as 10 speed ultegra.

    The Shimano triple 105 uses the Octalink V1 splined bottom bracket. I think the Shimano 105 group is the best value for the money from Shimano; I knew lots of folks that raced on that stuff.

    I think the Shimano set cost about $200 whereas I believe the Bontrager is over $300.

    Which crankset is better depends on who's advertising your reading!!! One would hope the more you spend the better the component, but you and I know that's not always the case.

    I've had both and think as far as quality, they are very similar. But, all things being equal, the Shimano would probably be what I would think is better simply because of the availability. I would think the Bontrager is much more limited in who has access to it.

    No way I'm paying $300 for a Bontrager crank.

    Ultegra triple octalink for $90 http://www.nashbar.com/profile.cfm?c...0Road%20Cranks

    105 triple external for $185

    The Ultegra at that price is basically the main reason I bought one

    the better crank is the bontrager.

    the better value crank is the shimano.

    i cant see how anyone can claim that a square taper/octalink/isis system is better then the most recent external systems.

    If we're talking 10-speed the 105 triple comes with 50-39-30 chainrings, that would be the better choice for me and, depending on your needs, it may allow for a slightly smaller cassette.

    What's better about the external systems? Stiffness? We're not going to claim that stiffer is faster here are we?

    Regarding a good crank value: Ultegra 6500 Double for $70!!! http://www.pricepoint.com/detail.htm...offer=EM071EM2

    The 10-speed 105 and Ultegra cranks are both external bearing and install the same way but they are not Octalink.
