I've been beating my head against my desk here trying to track down this answer on the web or in the
archives to no success. So here it goes..
A time trial rider sets off on my made up tt, this course is perfectly straight and has no altitude
change for 100 miles. The bicycle is a TT styled w/ 650c wheels. The rider is very aero and can
average 250 watts for the entire distance.
Now then to my question I'm trying to figure how much time the rider can save by riding with
tubular's vs clinchers by strictly a weight aspect and how to reach that answer.
So the tubulars weigh: Zipp 404 650c tubulars set = 1177 Continental Podium tyres 240each x 2=480
Not sure how much glue weighs when it dires?? Aprox set weight=1657
The clinchers: Zipp 404 650c Clinchers set= 1523 Continental Supersonic tyres 145each x 2=290
Innertubes 65each x 2= 130 Ritchey Rim tape 30x 2=60 Aprox set weight=2003
So the difference is about 346 grams.
Anyone have an idea how much time savings that would amount to after 100 miles? Maybe I'm asking an
unanswerable question or possibly a 101 level question, I don't know.
Thanks Chris
