Does no one believe tubulars are faster?

Maybe not a guru - just keen on testing stuff. No-one else I know of, including manufacturers, have this data available in an unbiased way.

On Google wattage there has been a lot of talk about poor performing tires and the wattage increases required to power the wheel:

* Group member Stuart Lynne reported 25-30 watts more power required to average 40kmh with Zipp 404 front/rear with Tufo S33's compared with clinchers on Bontrager aero rims
and 1-2 minutes slower in 3 TT performances than expected.

* Mr. E reported Tufos slower than clinchers

* Gary Zyriek reported similar findings

* Opie OsCO reported similar findings (same thread above).
* Gene Fowler reported 225 watts to roll at 25 MPH @ 85 cadence on rollers with Tufos, 145 watts with clinchers, same speed/cadence

Feel free to use whatever you like, but if there are ways to make things faster with relatively little effort, I'll take those gains thanks.
