IB14: Wheels Manufacturing Eccentric Bottom Bracket Gets Official

The problem with both this and the BEER EBB is that depending on how much chain slack you have/where the slot is located, you may run into problems where you can’t get a spanner in the slot because your chain stays are in the way. In addition, the bolts do not provide a strong enough of a link between the two halves to spin both sides together by applying the spanner on one side.

What would be ideal is to have both sides connect with a solid interface inside the shell (see the prototype version of the PF30 EBB from Niner) instead of being two separate pieces. The way to do this would be manufacture it all as one piece (think of a bone, with cups on the end, and a connector in the middle) then cut the thing in half, and have it re-attach with bolts. In addition, have some type of slotting that you can reach a slot, no matter what position the ebb is in. For example, I put some holes into my Beer EBB so I could fit a 4mm wrench in it (see link)

About time

You can get one now from http://www.beercompoenants.com if you want the original.

Other than being offered in a GXP option, how does this differ from the Problem Solvers BB that’s been out for a couple years? http://problemsolversbike.com/products/eccentric_46_bottom_bracket

1. All my bikes that could use a ebb are threaded bb.
2. Any new hardtail I buy will have adjustable dropouts of some sort, regardless of use. Old rigid seem to inevitably turn into ss (at least for me)
3. Apparently I am not the market for this…

I would love to hear the answer from Wheels to Andy’s question.

These are held together with two M6 bolts theaded into alu. I expect the threads will pull in the alu before a frame cracks. My Beer BB has been perfect (thought I do use carbo grip). Follow the instructions, use a torque wrench and maintain common sense.

@codyfish, no ABW is correct, that problem solvers part is for a pf30 shell (the diameter is 46 mm, the crank’s spindle is where the 30 comes from). bb 86/92 shells don’t have a large enough diameter to effectively tighten a chain using an eccentric bb, that’s why nobody makes them.

I haven’t tried the beer components one, but have used the problem solvers variety which didn’t work well. FSA also manufactures one that works very well, its the one I currently run. iirc, it’s also a fair bit cheaper than the PS one too.

The Beer EBB slips. I had it in a carbon frame and not even carbon paste would hold it in place. I had bent bolts because of slippage. It’s not a good design.
