Hi there!

Sorry if there is any other topics which has to do something about this, but:

I have a Cube Agree GTC with the BB91 Press Fit bottom bracket. It's been great and everything, but I would like to switch from Powertap to SRM/Quarq. Now: the SRM DA (7900 and 7800) are pretty expensive and there are some cheaper products on the market -for example the Quarq cranksets.

The only problem is the bottom bracket. It accepts only Shimano HT2 cranksets, so I can't go with the cheaper Quarq Sram models. Would this bottom bracket: http://www.sram.com/truvativ/products/truvativ-pressfit-gxp-bb solve the problem? If not, is there anything to do?

Thank you very much!!!

If you have new crankset with GXP. You need two bearings MR2437 with special spacers and spring - Enduro Bearings

Thank you! So I buy a Quarq Sram crankset which requires a GXP bottom bracket and then install for example this: http://www.ebay.com/itm/ENDURO-bearing-2437-kit-crank-FSA-TRUVATIV-SHIMANO-/370592682821?pt=Cycling_Parts_Accessories&hash=item56490b9345#ht_500wt_1416 or this: http://www.ebay.com/itm/ENDURO-bearing-2437-kit-crank-FSA-TRUVATIV-SHIMANO-/370592682821?pt=Cycling_Parts_Accessories&hash=item56490b9345#ht_500wt_1416 ?

What kind of special spacers and spring? Where can I find them?
