Here's what I'm currently riding. There's a fair bit going on that's being tested.
First off, it's one of a shortlist of 2 for a design which maximises hold without losing too much hold. That's a tricky balance. One way is to narrow the mat. That does the job but leaves you with a mat that potentially bogs in weaker waves and flat spots.
The other thing here is that I'm testing a new sealant for the grip. I spoke with the tech guy at the company and, if this does what it says on the tin, this has the potential to be very pliable but also very durable. 😎
Finally, I've welded the valve on to the mat.
This is a design I've been working on for a while. There are plenty of valves out there designed to be welded in but none of them are so good a design as the Boston valve, after modification. These valves are made to be stuck on, rather than fixed in, so I've had to do a lot of work to sort this out.
Worth it though I think.
