GXP BB grit problems

I am having a consistent problem of grit inside my GXP bb. I have an Omnium Truvativ crankset which I love but the GXP bb seems to have road grit inside the bearings. I probable ridden 1500km or more since I have built the bike and have read online that these bbs don't have the longest lives. Whem trying to service it I can remove the cups, the rubber race and the metal spring but the bearings are sealed and impossible to remove. I have cleaned as best I can and regreased but this only seems to soften the problem for fewer than 100kms.

Has anyone else had these problems? I know that the crankset is pretty popular, it was recommended to me on this forum! Should I replace the bb with a hope bb and adaptor as I hear they last longer, this means shelling out another £80, or a new crankset entirely?

Thanks in advance for any advice, bike noise drives me nuts and and not have a buttery smooth motion is just the worst.

Get your frame sorted out.

Thanks for finding that for me. The frame is brand new but never chased and faced. Are you saying the answer is to buy a new GXP, remove the old one which I can't get the grit out of and take the bike and said new bb to the shop to be chased and fitted?

at which point would it not be better to get a better bb if I can afford it?

Remove the old one - it's dead

Take to shop to have frame faced / chased

Install new one

The spendier BBs might be a bit more resilient but you should be getting at least 5k road miles from a £15 sram team BB.

Thanks for the advice.
