    Clydes and EBBs

    Considering a Singular Gryphon for Christmas, and it ticks a whole lot of boxes for what I need and want. Except one: it's got vertical dropouts and an eccentric bottom bracket.

    I have no experience with EBBs, but I'm wary of increasing the mechanical complexity of my bike, and I'm 125kg/275lbs.

    Does being a heavy rider increases the risk of EBB creaks and failures, and are they hard for novice bike mechanics to adjust and maintain?

    An EBB is no an EBB. There are a couple different designs out there; from what I can see it looks like Singular uses a set screw/grub screw design, which IMO is the worst. I would expect that to creak...
    A BB shell that clamps the eccentric could be quiet and work well. IMO set screws are never a good design for anything ever.

    The EBB on the Gryphon is a Paul, which is one of the best component makers out there. MUSA, no less. I don't own one, but reports are they work great.

    Thanks for the info.

    Building a frame up, if it happens, so I'll get a choice of BBs.

    The Bushnell EBB works great I have them on two different bikes and I am an aggressive rider and weigh close to what you weigh. These are replacements for the stock Cannondale EBBs, that were hard to adjust and keep from coming out of adjustment. I am a huge fan of the older Made in USA Cannondale frames but their EBBs are junk.

    Good pricing from a reputable retailer:

    You can get them for less on eBay, I am just concerned that the ones on eBay are copies not made by Bushnell.

    Thanks for that. EBBs don't enjoy the best reputation, so I'd better read up so I know the differences.
