I started back riding this past Friday after being off the bike 8 days on vacation. Did three hard days of mountain biking and camping after returning. I felt flat last night and struggled to keep my power. Not a bad 40K just not a great one but good training I guess.

Mine from the weekend:

http://www.strava.com/activities/75387458

New bike - Canyon speedmax set up in exactly the same way as my previous bike (Planet X stealth) with same wheels - Tri-spoke and corima disc.
I have been using the Aerolab analysis for some time on my Planet X and i have always found a range of 0.22-0.23. The first ride on the Canyon and i'm under 0.2. Is it possible that this is due to just the frame?

James, well done. Does seem like a big drop. Any other different equipment and exactly the same stack height and reach?

Canyon told me it was the same as before and I've just measured everything myself - the saddle is 1cm further back than before otherwise identical. Stack = 580mm, Reach = 500mm
Same wheels, same tires, same skinsuit and same hat.

Pretty pleased with the RoI really :)

Maybe... which Planet X?

Also, can you give me some info so I can analyze your race? Total weight, PM type, tires and tubes, road surface condition, traffic frequency and relation to you... I think that is it.

If you want to have some fun...

here's a 50mile TT i did on the same course on my old bike:
http://www.strava.com/activities/59185197

Both days were slightly damp - a bit of rain in the air but no more - and both days were windy but from opposite directions - the course is pretty open so not sure it should make too much of a difference.
Only real difference i can find is a 5C temperature difference between the two.

I weigh 63kg, using a Power2Max with Doval rings and am on Challenge Criterium tubs.

In both cases the road was medium busy but it is a dual carriageway so the cars tend to give you a lane to yourself. Road surface is so-so.

Just looking at 2 runs over the same segment for each, I get .204 for your new bike and .231 for the old one.

That's huge. Which PX frame was it? Any other parts or clothing changed?

PX stealth. Same hat, same overshoes, same skinsuit, same cranks...the whole lot. Maybe the Canyon is just awesome :D i'm trying to track down a picture from this weekend for comparison
