Have used others in past but Orange seems to seal better. Have used in Hillybilly race with no issues. It does dry up after a few months and needs to be topped off in tires
As lifelong fan of tubulars, the puncture used to mean replacing the tire. Now I can wear a tire out before replacing. Also no roadside struggling to change them. What a money saver!
Rode 20 miles with a 58 inch screw in the tire and this stuff kept enough air in tire to make it home. Works great for 5 month then slowly loses it's leak stopping power. I use the removable valve stems to put it in the tire, this brand does not plug the valve stem and flows in with just squeezing the already beaded tire. I have used this brand for 3 years and have used probably 4 quarts during this time for MTB, gravel, and road.
