    mmmm Shiny Cranks

    Truvativ Ominum track cranks, external BB, 144 BCD. I like it!

    Note: 'for the train spotters', Spencer Street back drop in the webpage.

    Hey they look pretty nice. The specs don't mention the Q factor tho - I wonder if the outboard BB limits it... The ones on the website look better than the example photo :/

    What's with the Spencer St image? ahah

    Yes, Q-factor will be wider than a std. BB. Probably not so ideal for the track, but OK for the street.

    If it's the first outboard BB in the world wouldn't they have made the cranks to compensate for the extra width of the matching BB (think Shitmano Saint)? Also having a much thicker spindle would enable you to have a laterally thinner arm at the arm/spindle interface yes?

    I would think that a company like SRAM/Truvativ wouldn't have made the same fuckup as Paul did with their original stuff.

    On the trainspotting topic, isn't that the chimney thats going to be pulled down? The one thats behind the left side of the crank front page...

    Wouldn't that just reduce the amount of thread for the pedals = not good?

    And would a thinner arm introduce unwanted flex?

    No. I do not ride for fashion and I do not care if your bicycle is prettier than mine.

    Sorry BB spindle, not pedal spindle.

    Nah Christof, The outboard BB gives better BB rigidity, which is largely unrelated to the crank arms. The crank arms of an outboard BB crankset are still as beefy (as a square taper/ octalink etc crank arm) to keep crank arm flex to a minimum as Des described.

    The Q-factor on an outboard BB will generally always be slightly wider than other systems as there's a limit to how much your spider can 'envelop' the BB. Watch this space though, they're bound to get narrower in time...

    Retail price from a US website is quoting $220.0 USD which is approx. 270.00 AUD (not sure if that includes BB)

    Hmmm interweb confusion, I'm postponing this discussion for a more appropriate time.
