asked by: a guest Will this fit an older Niner EBB Bushnell that used set screws.
anwered by: a guest If you contact Bushnell directly, there are shims available for 55mm and 57mm ID shells. bushnelltandems.com
anwered by: cmcmann The EBB you need for the older style niner frames needs to be 55mm in diameter and 68mm wide. So this doesn't look like it will work. Niner still sells EBBs for their older style frames though.

Replaced a poorly designed Cannondale EBB with the Bushnell. So far - works great, adjust easier and doesn't seem to freeze in the frame like the Cannondale unit did. Would be nice to be able to set the inboard outboard alignment once installed but it's not hard to align the chain so that's a minor gripe.
Price is a bit high for what it is but at least it works.
Expensive, but worth every penny. Original (cheap) eccentric bottom bracket (Cannondale) on 2011 RT2 started creaking. I hate creaking, as my bikes must be silent and well tuned (I am picky!). Tried to adjust, but it basically fell apart. This Bushnell is the first EBB that I've had which works like you THINK it should. If you unscrew all the way, then it's finger loose. If you tighten to torque spec then it won't budge (and won't sqeak). No hammers, no frustration. All is tuned, adjusted, and SILENT. This is a 'set it and forget it part'. Just buy it and forget what it costs -- the quality and ease of use outweighs the price. Good service by Tree Fort Bikes, too!
