THE ROADMAN VERDICT.
A water-based road and gravel sealant rated up to 110psi and designed to seal holes up to 7mm.
Why I recommend it
Road tubeless needs a fast-flowing formula that works at higher pressure. This is easy to add through a Presta valve and comes in ride-pack and workshop sizes.
Who it is for
Road, gravel and cyclocross riders using tubeless tyres.
Who should skip it
Tube users, riders mixing sealant brands or anyone unwilling to check levels every few months.
What it gets right
- Works up to 110psi
- Designed to seal holes up to 7mm
- Ammonia-free water-based formula
- Available from 80ml pouches to bulk refills
Where it falls short
- Needs checking every three to six months
- Should not be mixed with other sealants
- Large cuts still need a plug
