Works well.
Works ok. Just ordered my second one. After about 4 years and 4000 miles mine needs replacing. It got very creaky and looks like it rusted out on the non drive side. I don't really do any obstacles but do stand up on my pedals.

Very well made product
High quality throughout. Been using it for several months on my cruiser to-from work, and it works very nicely - NO problems whatsoever.

Found this hard to find item
Exactly as advertised and it fit perfectly my Ellsworth Truth. Would buy from these folk again. Thanks!

So it's worked well but only have a couple rides on it so far. No creaks.

$30.00 for the race face compatible ISIS tool.
I can’t evaluate the feel & fit of this bottom bracket yet.... My LBC’s don’t carry this proprietary installation tool, and my standard Shimano tool will not fit over their hub. What I can tell you is I will most likely not be buying race face again. I do not appreciate being price gouged for a simple installation tool, ( whereas the shimano version is less than $7 bucks.

Week bearings
Very week bottom bracket, bearings went out after five races.

Maybe I'm getting good service from them
This is my second Race Face replacement in ten years. Both started creaking within a few days. The bike shop says these are highly-stressed and should be changed every year. Maybe I'm getting good service from them, but I'm going to try another brand next time, just to be sure.
