@PinaRene, thanks for the warm welcome.
Question Frank - Would love to try Terokal 2444 - but is it heat resistant enough ?
The only problem I know of is that it sticks so well you may have to cut the tubular to get it off the rim.
I use it as a base layer on the rim mostly. If you go full Terokal you will definitely feel the reduced rolling resistance just as I and friends of mine do.
Applied by thin layers but well spread it sure does its magic for me.
O yes, I know some think it's just a myth but tubulars made of natural rubber aged properly do puncture less frequently. The rolling resistance penalty is really negligible.
FWIW I'm running 10 years old Veloflex Carbons that have seen the better side of 60.000 km of leisurely rides and are still good for more mileage.
True I do not race them but I do push them through all kinds of rough terrain. I can still do Landen-Namur (55km) in about 2 hours on these babies with peaks of 55km/h. That's a windy stretch with quite a few crossings and it ain't exactly flat either. Just saying.
So yeah, give it a trie it may surprise you.
Being a snob is an expensive hobby.
