External bearing BB questions...
Ok, here's my question... What is the inter-compatibility between the Shimano, TruVativ, and FSA external bearing systems?
Reason I ask is I currently have a Bontrager(TruVativ) crank running on a GXP BB and I'm looking on e-bay for an lesser priced compact for a few more hilly rides later this year (IE: Marin Century out in Cali). I would really like to not have to bother with swapping out BB's or having to specifically look for another TruVativ, leaving me open to the option of finding an FSA (Shimano is too expensive).
Has anyone actually confirmed or denied that the GXP and MegaEXO will or will not work together?
