I’m overall positive about tubeless and riding 30c or 32c on rear. Both of those have allowed me to roll without flats (except for sidewall tears).
Vittoria Air-Liner inserts are a tougher call, I like them however you can’t do roadside repair if its a sidewall tear. But you can roll home per above. After 8+ miles riding them run-flat, that Air-Liner had to be thrown into the trash. I believetThose inserts are rated at ~1 year lifespan.
Any tips on deflating without the special valves? I just got a pair and installed them without the valves because they weren’t long enough for my 50mm rims. I can pump the tires up, but can’t get any air out now!
Dang that’s solid… I wonder how much the rolling resistance goes up using those strips. I’ve flatted out of 3 races this season on tubeless GP5000 S TR tires and I’m trying to think of every possible way to lower the chances of flatting out now!
I see that going from Continental Race 28 butyl tubes to Vittoria/Challenge latex tubes saves 7W for a pair of wheels at 45kph / 28mph on a set of GP 5000 tires. Looking at that chart you can see that weight isn’t what determines rolling resistance, the lightest tubes are the Tubolito S Tube and they are 3W higher than the latex that weigh 3x.
And that chart is race tubes only - it doesn’t include any normal or heavy duty tubes.
Without pulling up some other charts, the fastest tires all seem to have really thin and supple tread.
Before getting a road bike, I used Mr Tuffy on an old mountain bike with slick tires for the road. Definitely affected road feel. And yes it stopped the flats, but so did putting better Schwalbe tires on the bike.
Given all that, I’m having a real difficult time wrapping my mind around the thought that Mr Tuffy is an undiscovered gem for going fast without flats. Wish I had access to a drum and equipment to test it.
