Bat-ass Posted March 12, 2012 Share What options do i have to fit a Sram 2 x 10 X9 GXP crank in a BB30 frame?I know there are adaptors available, but which are readily available in SA and has anyone had good or bad experiences with these?Other option is to sell my GXP crank and fit a new BB30 one? Anyone been in this dilemmer before? Link to comment Share on other sites More sharing options...

American Flyers Posted March 12, 2012 Share You need BB30 adaptor, so that you can use GXP cranks Link to comment Share on other sites More sharing options...
Bat-ass Posted March 12, 2012 Share Dangle, I hope you right. I pulled up some crank / BB specs off the sram site and all i could see is "Pressfit GXP BB", but the BB shell in the frame needs to be 41mm dia.. BB30 shell is 46mm dia. So prehaps "Pressfit 30 GXP " is another one? Link to comment Share on other sites More sharing options...
Wyatt Earp Posted March 12, 2012 Share If your frame has the bigger shell, then you need the adapters, then the pressfit BB. Link to comment Share on other sites More sharing options...
Bat-ass Posted March 12, 2012 Share Ya, it seems there is an adaptor that the standard GXP BB threads into.Maybe a new crank is the expensive, buy right way to do this? Link to comment Share on other sites More sharing options...

manbearpig Posted March 12, 2012 Share Just to throw a hammer amongst the ostriches I heard a rumour that the Pressfit BB30 bearings don't last too long. The GXP ones seem better.... Link to comment Share on other sites More sharing options...
Bat-ass Posted March 12, 2012 Share problem solved... I just measured the bb shell and it's a press fit 30..which means a press fit GXP Bb goes straight in.. Link to comment Share on other sites More sharing options...

The GXP ones seem better.... that's interesting, cause the SRAM website seems to think the press fit bearings are far better protected from contamination and last better?

Seems you sorted anyway. Link to comment Share on other sites More sharing options...

Vinnydabutcher Posted June 12, 2012 Share Help me out here quick - same question, however my BB shell is 46mm diameter and 73mm width. The GXP pressfit BB is about 42mm diameter. What is the adaptor called that Im looking for and where to fnd it? Do I just have shims/spacers machined? What are the options? Link to comment Share on other sites More sharing options...
