I have been asked to test a top line road bike as used by a current world road race champion as they claim it is X amount more aero than other bikes. Not sure what me riding one bike with a power meter is going to tell me unless I compare it to all the bikes out there.
Manufacturers constantly make these claims. A set of wheels will take 60sec off your 40km TT but the comparison is with a set of box section clinchers. One of my riders asked what the benefit would be in buying a Campag Ghibli Disc over his Campag Bora wheels. I worked out for 16km a maximum benefit of 1.67 seconds. He still spent the $4000 on the wheel.
At least for things like wheels or tyres there are independent power or wind tunnel tests that can steer you in the right direction.
Are there more photos of this rider or even better some video? He is showing a fair bit of strain in that image and I wonder whether he isn't being pulled into a less aero position by the effort...
Right, it is only one shot and I don't perform bike set ups from photos or even videos unless it's one of my International clients and even then I would prefer they find someone suitable locally. But I think some flexibility tests and 10mins work with an allen key would be the place to start rather than changing cranks, whacking the seat back and up, shortening the stem and lifting it up.
