Tufo tape with Conti Sprinters—anyone run this combo? Tufo sealant—thoughts…
Last question, okay to remove my glued on conti and put it back on with the tufo tape?
Thanks in advance
Tufo tape + Conti tires = Not recommended. The believe the base tape cloth on Conti’s does not lend itself well to taping.
Definitely “no” on taping previously glued tubulars. The tape is meant for clean basetape and will not adhere well to the irregular surface of a previously glued tire.
FYI, I am not a fan of taping tubulars. Tests done by USA Cycling show that tape is much weaker than glue. With glue, you can get adherence over the maximum surface area of the rim/tire combination. Yes, it takes at least two days to properly glue a tubular but why not go with the most proven method?
Anyway, hope that helps.
IIRC, tape is really SLOW as far as rolling resistance is concerned. Jackmott or Tom A. could provide more insight on that I’m sure

you remember correctly. Tufo’s are also slow. I always advise my competitors to run tufos with tufo tape

Contrary to what I had thought the Tufo Extreme Tape is really not that bad with respect to rolling resistance. Comparing a Bonty RXL Pro properly glued with the same model but different tire showed ~ 1 watt per wheel difference. The glued tire rolled better.
hmm well how bout that!
Is that compared to the “standard gluing method” that you use (i.e. 8,492 coats? =D )

Yes, 3 coats on a “bare” rim with 2 coats on the base tape - ~ 2 tubes of Mastik One in total per tire. Since there are variations from tire to tire of the same make and model the difference could be slightly more or slightly less. (
I prefer gluing for a number of different reasons.

iirc tape is not especially slow, AFM could chime in
eidt - he already did!

You can do it in one day and have a great tire to rim bond. Put a coat on each early in the morning. Go back about mid-day and put another coat on each. Finally go back at night and put one more coat on the rim and then mount. Let it sit over night and you will be good to go.
True, if you’re in a hurry, you can do it that way. Ideally though, the first coat should dry 12-24 hrs, and each coat after that should dry at least 8 hrs.
You need an overnight of stretching as well though if you want to have a clean mounting process. And at least another full 24 hours to dry. 15 years ago I had a valve spring fail on a tubular I glued the night before and went about removing the tire the next morning. It was still quite tacky and soft inside of the rim edge margin. Enough so that removing it was easy compared to a 24+ hour glued and cured tire. 12 hours isn’t enough IME at least with the standard glues.
Not replying to you but to everyone in general…
Every tubular I’ve mounted has been a one day job. Every tubular I’ve dismounted had been very difficult to remove, however I didn’t dismount it the day afterwards. Had always used Conti glue too.
X1 - When I started using tubulars I did not know the “approved way” of glueing. Coming from a welding background years ago, I run a bead around the center of the rim (1 tube of glue). Let it tack for 30 minutes or so and mount the tire and inflate. Use a little warm soapy water on a rag to remove any excess. Lay the wheel flat on the basement floor and flip it over every 30 minutes or so for a couple of hours. let it sit in the basement for 24 hours and it is ready to ride. This has work well for me for years. I ride tubulars for training and racing.
I must have done something wrong, then, Al. The one time I used Extreme tape with some Conti Sprinters on Hed 3s the whole setup felt like quicksand compared to the previous Vittorias w/Mastik glue job that I had on the wheels. I’ve never had confidence in the Tufo tape since then. (And honestly, after you started posting your RR chart, I sold the Heds and have been on clinchers ever since.)

There is a significant difference between the CX 23 and the Sprinter - approximately 10 watts just on the tires alone. The wheel I tested used the Extreme (temperature) tape - maybe there is a difference ?? Did the wheels/tires feel sluggish or you noticed a decrease in speed. My experience with the Tufo S33 Jet tubulars was that everthing felt OK although the ride was a bit harsh but I had unexplicably (at the time) lost ~ 1 minute per 10 miles. Arguably you have a better set up for a triathlete on clinchers - hopefully all is well with your conversion. (
