I'm just looking for some opinions....hopefully from people who have used an eccentric BB.....i'm planning a new frame with some very interesting features....i NEED to use vertical rear dropouts which means an eccentric BB is the way to go...my question really is this....
Which type of EBB do you think would be best....
a bushnell style with a wedge....nice and clean as no external set screws or pinch bolts are needed...
A twin pinch bolt,split BB shell...
Or a twin set screw style...
As i run brakeless my main aim is for the one which has the least chance of slippage...weight isn't my main concern....nor looks to be honest.

Thank you....:)

Bushnell. Without a doubt. The lightest, lowest maintenance and best quality EBB out there.

. . . or eccentric rear hub (White Industries) ?

Cannae use eccentric hub for reasons i'm not at liberty to divuldge yet...;)

VB....i keep reading about the bushnells being creaky?...are you having one on your new bike?...i looked at the carver bikes version which is very similar but uses a nylon sleeve to prevent the creaks.

I've heard about the creakiness too but the one I test rode was silent. Word is that the creakiness arises if you haven't greased the bracket liberally before fitting and then fail to take it out and clean it before liberally re-greasing annually.

I've decided on sliding vertical drops on my new build. But the Bushnell EBB was the choice until I saw the Paragon Machine Works sliding drops.

Yeah,the paragon drops are nice....but again they're out of the question for my frame.

Why? I'm having full mudguards if that's your problem. Vertical drops for position, sliding drops for chain tension... mudguard will be fixed to sliding drops and pivot around the rear stay bridge.

You are building up our expectations ! I am a little scared.

can anyone help me here.... if a frame is 57cm TT, 56.5 CT, 55 CC do you think it will be ok to ride for someone a shade under 6 foot. when people describe a frame as, say, 56cm, are they usually referring to the CT or CC length??

I'm designing a special dropout specific to my requirements....nothing to do with eyelets or tension....just needs to be a certain way.

Does it have facility to attach anything? I can see Archies Panniers on the distant horizon.. :-P

hehe.....no....just something a bit more thief proof....;)

hmmmmmmm, bolt-through rear hub???

oh murtle.....now you know i can do better than that...:)

i meant bolt-through rear dropouts

Maxle style?

I have been measuring up 20mm bolt through front hubs, looking at something in the style of the shimano front hub/bolt on sprocket thing that londonfixiebike do, but with a 110mm wide 20mm bolt through axle. now I have the sliding/ removable dropouts on my MTB silly thinks like that can be tried out :)

I've ridden a Phil Wood set-screw type EBB through a very salty, slushy Canadian winter. 220lbs rider, really low gear (lots of torque). Never shifted, slipped or creaked. Set it and forget it. The only time I have adjusted it was to accommodate for chain stretch. Very happy with it, and it's a lot simpler than something like the bushnell.

i recommend a phil wood. it's so simple to use as the only 2 moving parts are the screws. i would steer clear of the bushnell unit. they are known for creaking and have to be stripped and covered in coppaslip the expanding wedges and allen screws are prone to seizing.
i have been using a phil wood on my ss mtb for the last 3 years, take it out and regrease once every year when i fit a new chain, never slipped or creaked.
Independent fabrication use phil ebb's if there was something better available at whatever cost i expect they would use it.

I had a Bushnell on my Salsa and it was great never needed cleaning never creaked pieace of piss to set up. All good.

Forgive me for asking a daft question and bumping an old thread, but are the Phil Wood EBB suitable for a road bike frame or just Mountain bike/hybrids?

Any bike that has en EBB size/compatible BB shell.
