I use orange seal in latex tubes in all my wheels. It's doesn't add to rolling resistance from the tests I have seen. It's seals better than Stans. Both work, but orange seal seems to secure the puncture faster and at a higher pressure. This setup kept me rolling this weekend when some jerk spread tacks all over our TT course. The only downside is that you need to keep the wheels inflated and rotated reasonably often. I seem to get about 4 months out of a tube before the sealant dries up and the tube gums together. It's not a cheap setup, but fast and secure.

For what it's worth, I wouldn't use that tire on an H3. Give a 20c supersonic a try. The H3 was designed to run with a narrow tire.

a- thanks for the orange sealant tip
b - h3 plus? i think its a good bit wider than older h3. the hed peeps who were at the rally team camp suggested the whole set up - my peeps are helping make it only mildly financially ruinous! wheel is in transit and i'm getting the tubes/tires now - i'll let you know if it all seems to work soon.

Is it the new h3+? I have been really curious about that wheel.

h3+ (h3 plus) - yes - this wheel. if my understanding is correct - its plenty wide enough to roll better with a 23 (maybe even a 25). looking forward to trying it out, esp. since i need all the speed i can get (who doesnt?). will be especially happy if i have no flats in actual tt or ttt races.

one more q - which tubes do you use (i'd assume a removable valve makes injecting sealant easier (maybe even the only way?)?)?

and is there any trick when you have a deep wheel - put sealant in tube before its on rim inside tire? and i'm guessing with no valve in tube when you are applying sealant - sealant goes in with no air in the tube......

sincerely, rick

I use vittoria tubes with removable cores and put the sealant in with the core removed.

Bumping this thread back to life because I was wondering how your experience with sealant went.

I run the same front wheel with a Conti Attack - Vittoria Latex Tubes - Orange Seal. I did a long ride last week and flatted repeatedly, front and back. The Orange seal appears to do nothing except create a giant mess in your tire after the tube fails.
