Reserve has made a name for itself by making high-quality carbon wheelsets for MTB and gravel, it has since released its Fillmore valves and it now offers its own tubeless sealant and rim tape too.
The sealant uses Reserves own formulation using a biodegradable natural fiber to provide the hole plugging performance, although there are no claims to how biologically sound the sealant is as a complete formula. Reserve claims that its sealant provides a more durable seal when compared to the best tubeless tire sealant on the market. When Reserve says durable, it's claiming that the seal formed will 'hold higher pressures on bigger holes for longer periods of time'. That should mean that the sealant will not just work for mountain bikes, but also for gravel and road applications as well.
The sealant is claimed to be able to block a 7mm hole, which is about on par with other brands' claims, and riders are recommended to use around 100ml per MTB tire although Reserve hasn't specified what the refresh intervals are.
There is also rim tape available too which uses a silicon-based adhesive that should leave no residue. It comes in three widths – 29mm, 32mm, and 34mm – all in a 10m roll which should be enough to tape up four wheels.
The sealant will be available in 200mm and 50mm bottles which will retail for $9.99 or $24.99 and a roll of rim tape will cost $24.99.
