- Rockstop® is a tough, highly shock absorbing rubberised polymer designed to fit on your MTB rim and protect it from dings, and your tyre from most impact punctures and burping.
- The geometry of the cross bridges forces the Rockstop® edges against the tyre sidewall, so that if you hit a rock it's the shock aborbing meat in the tyre and rim sandwich, preventing pinch punctures and rim damage.
- Rockstop® 27.5" has been designed on a 30mm rim and will suit 23-34mm rims.
- It's easy to fit.
- You don't need any glue.
- You don't need any extra valves.
- It comes ready assembled.
The long and short of it...
do you get when you cross a bunch of hardcore mountain bikers with a
bug up their ass about something, and a group of pointy headed polymer
engineers who only get good ideas after a few beers?
Rockstop is the snarling love-child of the Grizedale Mountain Bike Hire
Centre and Urofoam Ltd - experts in all things polyurethane.
Pat (the manager) and the guys
at Grizedale were looking for a different sort of tyre insert, one that
was easier to fit, and that you couldn't tell was there when you were
riding. But it still needed to be tough enough to protect rims and tyres
under hard impacts.
10 miles down the road
is Urofoam - specialists in technical problem solving in industries such
as oil, mining, automotive, and sports. Immediately intrigued by the
challenge the well-oiled machine sprang into action.
It wasn't as easy as it looked.
It took several attempts - lots of alcohol and some regrettable
language - but we got there in the end!
To help test the ideas we
managed to get alongside a fine group of riders who ride-tested the
various versions and gave us their feedback
So everyone got stuck in and Rockstop is the result.
None of this would have happened without Pat and his team, so loads of respect to a genuine Lake District partnership.
