currently ride an FSA compact crankset on my BB30 Cannondale Slice. My road bike is a Cervelo RS with DA 9000 crankset etc, though I do not necessarily need power meter on it, but would be interesting sometimes. I train on a separate CompuTrainer setup
wanting to move on to crank-based power meter - here are my options that first come to mind:
get a BB30 SRAM Quarq or Power2Max crankset
use a Rotor (for example) BB30 to 24 converter and use any standard BB Quarq or Power2Max
what’s the ST crowd-opinion on pros / cons? any other options?
I’ve got the BB30 Quarq (S975) and use it in normal configuration on my BB30 tri bike and with a Rotor BSA-30 BB adapter on my road bike. The BB30 IA that the 975 uses is nice in that the spindle is attached on the non drive side, so I bought a 2nd crank without the powermeter and can leave that installed and just change the right hand side of the crank between bikes, in about 3-4 minutes, but the 2nd bike is always ready to go without removing the spindle from the BB. I’m just worried that if I tap it in and out of the bearings enough they will get loose and start creaking.
I said the same about not really needing the PM on the road bike until I got accustomed to having the power numbers and then did the change on the road bike.
