Thanks for replying mate. I've been busy and not on the forum of late also.
Bloody computer died also so we bit the bullet and got a mac. I've had a gutful of windows over the years
I did a bit of research on the enduro adapters and it might have been your thread on the Cervelo forum that turned me off them.
I've got the 177.5 cranks in now using the wheels mfg adapter. All good touch wood.
Not sure about the longer cranks on the roadie. They worked on the tt but not sure on the roadie, I think the legs might fatigue a bit quicker with them. Early days yet though.
That rotor bb looks fantastic. Good way around a terrible (IMO) system. If I persist with the longer cranks or upgrade to shimano 11 sp that will be the way to go. Thanks
