- Tubeless tyres are required for South African mountain biking – with rough singletrack and thorns creating significant puncture risk.
- But any tubeless tyre set-up, needs its sealant to be topped-up. And that can be messy.
- Local cycling lubricant specialist, Squirt, has a clever new sealant product – ideal for home mechanics.
At earlier Cape Epics, when foreign riders remained ignorant of South Africa’s testing terrain, the sight of frantically patched tubes was a familiar scene on most stages.
Mountain bikers and tyres engineers realised many years ago that rocky trails (and occasionally thorny biospheres), don’t play nice with traditional tubed tyres.
The sticky stuff that makes tubeless tyre work
But for all the benefits of tubeless tyres, they require sealant to create that airtight interface between tyre and rim. And sealant doesn’t last forever.
Experienced mountain bikers know that sealant lasts a season. And replacing it isn’t necessarily pleasant. Pouring sealant into a tyre without making a mess of your hands, clothing, garage floor or emotional state of being – isn’t easy.
To make the sealant top-up less of a technical trauma for mountain bikers, Squirt has produced the EasyFill pouch. It contains 120ml of biodegrade Squirt sealant and its flexible packaging can be recycled.
No mess. No fuss.
Danie van Wyk, of Squirt Cycling Products, recognised the demand. "As riders we know all about the hassles of tubeless tyre set-up and maintenance."
With the EasyFill pouch, riders have much less spillage risk than pouring from a larger plastic container.
It has an appropriately sized nozzle that connects to the valve hole in your rim and that means all the sealant you need goes into your tyre, instead of everywhere else.
