I could do with some help on a bike build...
I've installed a BB86/92 Trivatuv pressfit GXP bottom onto my Production Privee Shan frame. I used a headset press and everything seemed to go smoothly.
When I insert the crank (SRAM X1) I can hear what sounds like a small amount of friction/rubbing between the spindle and the BB as I turn it. When I tighten the cranks they doesn't spin very freely, maybe 1 or 2 turns.
Finally after fitting the chain, I can't shift into the easiest gear. When I try the friction between the crank and the bottom bracket increases. If I try very hard to change up I can make it so I can't spin the cranks at all.
My best guess is that the bottom bracket is slightly misaligned and when I try to shift into the easiest gear the lateral tension on the crank is causing lots of friction between the spindle and the sleeve of the bottom bracket.
