Yup, I use that setup on a BMC SL01. Get a package of shims, you'll probably need them.

Holy crap I have a 2012 BMC sl01! What a coincidence. Could you tell me how many shims you used on the drive and non-drive side? Where's a good place to order the bsa30 bottom bracket? Not many places sell it that look legit.

Just to confirm, you have the latest quarq riken correct? Not an older quarq with sram arms.

I had a 2008 P3 and it was threaded. I used the rotor bsa30 BB and it worked. I did have quite a few shims on there though and the same on my NP3 and S5, quite a few shims. I have the Quarq Riken BB30.

Did it affect the way it worked or felt having all those shims? Is the q-factor affected at all?

Yeah, totally. I've got a Riken on my P3. Actually, mine is a Riken spider on my original S975 crank arms, replaced under warranty.

I probably had to put 3 or 4 skinny nylon washers either side, and you need a wave washer for the NDS. Take a little care over maintaining the correct chainline. You've got it tight enough when the wave washer compresses slightly - but not totally flat - when you torque it up. Mine doesn't spin altogether freely, but it's not a worry.

I did have some difficulty with magnet placement, using the BB ring mount magnet. Ended up stacking up some smaller magnets. Works well but I do get the odd cadence drop/spike. I'm going to apply the firmware upgrade shortly that fires up the accelerometer.
