hope's decent, but no real advantage for the extra $$$, been using GXP since,.. well mid/early 2000's and the best one I've used so far is RealWorldCycling.com's ceramic... had 2 diff sets of cranks on it and it's still smooth, actually smoother than new. still using it to this day.. the same one I got in.. umm 2008 or 2009 I think?
BOTTOM BRACKETS FOR GXP CRANKSETS
They have diff grades and materials depending on your wallet.. the lowest of the ceramic's is the one I got.. was like just over $100 if I remember. Has save me $ over time as I used to go through BB's 1-2 a yr.
you can also get a bearing/seal kit from them.. Take the stock cups and press out the SRAM stock bearing and use their Bearings
GXP BOTTOM BRACKET BEARINGS FROM REAL WORLD CYCLING
Personally, I'd use the stock one till it's toast.. (probably 6-months

)
