I was recently turned to some postings on slowtwitch.com regarding Tufo
tubulars (with tape), and how they have dramatically higher rolling
resistance than both other tubulars and clincher wheels. Besides
citing some German magazine article where the tires were tested, there
is a member claiming that they train with a power meter and reported
20W difference between using their wheels with Tufo tires and a set of
decent clinchers. Others on the board are reporting equally disturbing
anecdotal evidence that Tufo tires are bad.
I used a set of LEW Palermos with Tufo tubulars (and tape) as my race
wheels last season, and having read these postings on slowtwitch, I'm
almost afraid to continue using them. I train with a PowerTap . . .
20W is a lot.
I know there are people on this group (Jobst Brandt, perhaps others as
well) that are experts on this topic. I accepted their statements that
the rolling resistance of tubular tires was more than for clinchers,
but always figured the effect was more or less negligible. Is this 20W
statement possible?
Additionally, I see from some posts that there is a recommendation to
use "track glue" instead of standard tubular glue . . . glue that is
harder offers lower rolling resistance. Is there any specific brand of
this type of glue?
