Now where did you come up with 92?

See link here for an analysis of his ride by a few riders at fixedgearfever.
24-26 pedal strokes for ~200m = ~150rpms.

I tried to count the revs off the video

It looks to me like 25 or 26 revs for the 200m, which, over 9.77s = ~153 or 156 rpm

And I know full well that the rules require one to use a fixed gear on the track. By "track riders sacrificing" I mean the sport of track cycling in general. A little synecdoche.

this isnt apples to apples. road sprints happen after 100+kms so everyone is already going to be drained a bit. road machines are also going to be a bit less efficient than a track bike (losses to deraileur pulleys, chain line, thicker tires etc.) endurance is a much an issue as pure power for a road sprinter.
besides, has Mcewen ever lined up next to a track sprinter on a track, with identical track bikes? not that i know of.
edit: i guess i got beat to the point already

i think Bayley was just playing with him. If he was serious, I'm sure he would've beaten him by more than half a bike length

Hey good for McEwen for giving that a go. Shows he's a good sportsman. I wonder how many of those amped-up 200 lb trackies would challenge him on a 200km road stage? Maybe they could put together a whole team of trackies and take on Predictor-Lotto?

good for McEwen for remembering how to ride a fixed wheel

The longest track events of the pure sprinters are the kilometer and the keirin. In the keirin they're paced up to about 30 mph over about 1.5 km behind a motor, then the motor pulls off and the sprint cuts loose.
There are occasional track sprinters that switch to endurance. Most recently is Marty Nothstein, who switched to crits and 6-day races at the end of his sprint career. He lost a ton of weight (probably almost all muscle) in the process and did pretty well in the 6-days. Gideon Massie was looking pretty good in the endurance events today at ADT, too.

Patrick Sercu and Russell Mockeridge were both World or Olympic Sprint champs and Tour de France finishers. Tom Steels was a kilo specialist before becoming a roadie. Stephen Pate was a world champion in the sprint and has won stages in the Herald Sun Tour in Australia.
Times have move on though - the sprint events have become much more specialised. Bos has said in the past he is considering making the jump from track to road after Beijing. It will be interesting to see how he goes.

The 200 is rarely considered an endurance event.
I don't see a lot of masters posting 10.8's at ADT. Go check the book over at tissottiming.com and see that a 10.73 would get you into the sprint rounds (top 16) at world cup last week. 10.79 is between 21st and 22nd.
