I am busy reading the 062 build tread.. at page 20 now.
seems BSA with GXP are the most popular option. No issues, no creaks, more used spares available. I was set on a PF30 because i can always go to a 24mm spindle with reducers and BB's, but the more i read the more i think BSA.
I am no mechanic or bike tec, but i am mechanically minded and do all our bike maint (4 MTb, 1 Road bike... kids and mine)
I am certain i can use a SRAM GXP XO1 / XX1 with a reducing BB with a PF30. I just think BSA have less issues.. fool and bullet proof, but it's a100g heavier frame. BB92 works well because it's wider, but the chinese frames are not a BB92 frame.. they just widen the BB cups.. Scott did it on the Scale and had issues. If your chain comes off it damages the carbon sticking out from the frame.
Comments wellcome.
