Hi,

I'm planning to buy a compact crankset and I'm trying to decide whether to stick with a square taper one or get an Ultra Torque one. If you have UT now and came from ST, did you notice a big difference? Any problems with increased noise and dirt contamination? Seemed there was a fair amount of complaints about that with OBB but I couldn't tell how problematic that was with UT. Finally, is BB facing really necessary?

Thanks a bunch in advance.
