    '12 Cannondale Trail SL 3R Crank and EBB Question

    I've swapped around nearly all the components since picking up the bike last year to suit my personal tastes and the crank is the last thing I'd like to upgrade. I've tried contacting Cannondale for specifics on the eccentric bottom bracket and they pass me off to my local dealer, who in turn, isn't willing to give up information without purchasing a crank from them before hand.

    Anyhow, I'm looking to swap out the Truvativ Isoflow 1.0G with Tange LN-3912 bottom bracket for a Shimano XT or XTR SS modded setup. I haven't been able to find any information on the type of eccentric bottom bracket the bike came with to see if it'll work with the Shimano or if it won't, what type of eccentric bottom bracket I need to go with so it will be compatible. It's also not clear whether or not my frame is a pressfit 30 style either.

    Does anyone know if the stock eccentric bottom bracket will work with Shimano or if not, what type of replacement eccentric I need to make it work?

    '12 Cannondale Trail SL 3R Crank and EBB Question

    I thought that was a BB30 bottom bracket with an eccentric adapter in it. Bit I could be wrong

    The bottom bracket is a BB30 attached to a separate EBB. I'm just not sure if the EBB is a standard or press fit 30.

Size:  36.4 KBI went with a new Bushnell EBB and the Shimano SLX M660-10 (modified) crank and have and no issues. My rig is the 2011 SL3 Trail 9ner. The bottom bracket threaded into the new EBB like any normal frame.

    Thanks for the info! I was just about to order a bushnell to see if it'd work.
