Seeing as these will only accomodate SRAM/Truvativ Cranks without adaptors (http://www.fisheroutdoor.co.uk//product.asp?category=110&part_no=BBASBB32&find_category=110&find_description=&find_part_desc=), I was wondering whether larger bearings could be fitted in order to fit any HT2/X Type crankset? Surely this would mean even bigger bearings, which has got to be a good thing. Only seem to come on Specialized's this year (SRAM's biggest customer) but seems to be a new standard that might be commonplace next year.

Who can read this bearing code? http://www.sram.com/truvativ/products/truvativ-pressfit-30-bb

Wheels makes adapters to fit Shimano/RF/FSA cranks to BB30 bikes.

I think the advantage comes from the bigger spindle not the bigger bearings.

Try it now.

hmmm, 61806 makes sense (30x42x7mm) however it would need to take 24x42x7mm to take normal cranks directly (like Hope) or 25x42x7mm to take them with the plastic spacers found on Shimano/Raceface. These aren't bearing sizes in production as far as I can tell.
Ignore my ramblings
