Did you fit P2M yourself? It's not very clear on their website if its compatible with Ultegra systemI own both a P2M (Mk2 varient) and a powertap, and of the two I'd recommend the P2M any day. My powertap has given me nothing but trouble and I wish I'd never bought it. Some things that have gone wrong:
1) Wheel going out of true constantly (despite being built twice by the best wheel builder in the Midlands)
2) Bearings shot after a nasty rain shower (within warranty so repair FOC)
It seems reasonably stable right now and I'm going to use it in my TT bike. The truing issue only happened under very high torque loads (ie sprinting and attacking on climbs), so it should be ok in a TT bike where the torque load is more even and less "jumpy".
Never had a single issue with the P2M...it's faultless so far.

There are many different versions of the P2M much like with the other crank based PM's, which one are you looking at? At least one is bound to work, if not half a dozen of the various versions. You will need to buy the right bottom bracket of course.

FSA Gossamer is Hollowtech 2 compatible (hollowtech 2 being 24mm Axle with outboard bearings.)It looks like Power is the right way for me to go as I need to get as much training benefit out of as little time as possible. I reckon that, eventuall,y the pedal based system is the way to go in terms of flexibility--can swop from bike to bike- and functionality--ability to split L/R foot power profile + abilty to monitor correct pedalling technique etc. So reckon I'll hang on for Garmin to bring their Vector system to market , hopefully sometime later this year
I agree with everyone else. Crank based is the way forward at the moment. Pedal based systems may never really take off, and their advantages are dubious anyway.
My next PM will be a P2M or SRM depending on fund situation. And that's despite being very happy with the Powertap so far. It also somehow seems that one power meter just isn't enough
The P2M is a crank and I chose the Rotor 3D system as it uses the same 24mm axel as all shimano cranks, therefore you can directly swap the Rotor based P2M into existing shimano BB's.
I've got a Dura-Ace press fit BB, do you think this would be easy enough to fit myself?
