Trials and street riders: Consider the Try-All “Rotation,” 20 X 2.5 inch, fits 19 inch trials rim (standard). Incredible rebound qualities for preloading and prehops, and the “sticky rubber” grabs like a climbing shoe. Uses a cleated pattern tred (like found on mountaineering boots) as opposed to the dot matrix tred on Monty and Luna tires.
Little pricey at 50 bucks (including shipping), and a little hard to find in stock, but it blows away the Monty I had on my KH 24.
I just got one the other day. Rides great.
Pros
sticky compound
flatter tread print (not as round as Luna) easier to balance on
Stiffer sidewalls
can run less psi
Cons
1/8 of an inch more narrow
more expensive
???
wear Could go quick or slow
only time will tell
The 35$ list price is for the 20 X 2" model. Trials riders will want the 20 X 2 1/2 incher, which runs 10 bucks more. Throw in shipping and it’s around 55 bucks deliverd to your crib.
The tire is made in Taiwan but is distributed through France – need I say more about availability? Unicycle.com and Bedford might do well to start stocking these since the Monty is basically not made anymore, and the Luna is a far lesser tire than the try-all.
Incidentally, “sticky rubber” technology was first developed by Charles Cole of 5.10 company (rock climbing shoes), and the “rubber” is quite durable. It’s also not rubber at all, rather a petrolium-based synthetic.
My understanding from my buddy who designs climbing shoes is that “sticky” does not necessarily mean soft. Relative hardness in synthetic rubber is measured by a measurement called “durometer,” and the durometer of the stickier climbing soles is pretty high – meaning the friction coefficient is not entirely determined by the durometer (hardness). I do know the best sticky climbing shoes wear as well as the old hard ones, and perform much better.
But who knows with the try-all tire. Doesn’t seem to be real soft, but it’s the first one I’ve tried so durability is still a question. I don’t much care if it wears out a bit faster so long as it gives me a slight edge.
Yeah, I’ve got an echo. It’s noticeably smaller than a monty of luna, but seemed to preform somewhat similar. It did seem to develop a bulge after ~10-15 hours of use. Unfortunately, that’s about all I was able to use it.
