Long story short. After 2 pressfit 30 bottom bracket installs on a 2011 Cervelo R3 (once by a shop and once by me, brand new one by me), it seems like there is a lot of resistance in the BB and does not allow the crank to spin freely. It turns but not without force. Any ideas to what could be going wrong?
What crank? I had same issues with a rotor crank in bb86. Turns out the crank was done up too tight.
Take the crank out and use your fingers to see if the bearings turn easily. if they don’t then either they have been damaged or the seals are really tight. If the bearing turn easily but the crank doesn’t when installed the crank may be improperly installed (something like too few spacers so the crank arms are binding on the frame or bearings), or the faces of the bottom bracket shell are not parallel and need to be faced.
Both bb bearings seemed really “slow”
I compared the resistance to 4 other bikes and they are hands down 2-3x stiffer
This is the first time I have used the pressfit 30 bearing and wondering if this is normal or not.
The SRAM GXP bottom backets tend to have a ~100 mile break in period - at first, they’re pretty stiff, but after a few hours on the bike, they’re smooth like butter. Maybe it’s the same thing?
Albeit a ceramic gxp bb, that seemed perfect out of the box.

Or at least as good as a SRAM GXP bb gets anyway 
They need to sack the guy who let that one go into production
