fyi, i don't know how many ppl are hot for gumwall tires but i was searching around online and found an interesting medium that should provide really good ride quality:
TUFO TUBULAR TIRES FOR CLINCHER RIMS: - totally new, revolutionary construction
- low rolling resistance
- no need for rim liner
- low weight
- no need to use glue
- the easiest and fastest installation from all types of tires, no tools required
- possibility of high inflation pressures
- distinctly the safest behavior in case of flats without endangering the stability of the rider
- in case of emergency can be ridden flat
- immediate use after installation
- construction and compactness is equal to tubular tires, riding properties are very close to tubular tires as well
Summary For racing purposes and quality training , or for a ride with feeling of lightness, tubular tires are the obvious choice. Their main advantage is significant saving on weight, not only on the tire itself, but also on the rim. This weight saving can amount for the front and rear wheel in total to 500 grams in comparison to the use of clincher rims and tires. Moreover, this weight saving is realized on the circumference of the rotary parts ( wheels) where, from the physical point of view, in case of acceleration, the low weight has far more importance than the weight of solid parts of a bicycle.
It is necessary to realize that races are won just by acceleration in the right and critical moment, as final sprint, catch-up with the peloton, break off from the peloton.
At the same time low rolling resistance and safety in case of flats are strong arguments for tubular tires. TUFO tubular clincher tire is quite universal. It can be used anywhere tubular or clincher tires are presently utilized (road races, time trials, training, cyclocross events, cyclotourism).
For those who switch from clincher type tires to TUFO tubular clinchers, there is no extra investment. They only have to replace three parts (tire, tube and liner) with only one - TUFO tubular clincher tire. Everyone will soon realize the advantage of easy installation and, in combination with TUFO sealant, the fastest and most effective flat repair without removing the tire from the rim.
