60 hybrid studs of my own imagination per tire, center row only in back, staggered in front, on Joe Murray Equilibrium Kevlar-Foldable tires, and mounted tubeless with winter grade sealant of my own mix, maxxis tubeless rimstrips. Currently they're sitting inflated at 50psi in my basement to verify they're not leaking at all still and also that there won't be one of those lovely explosive bead seperations later on when I'm riding with them.

Tire weight is 1005 grams each as pictured, Approx 5 Fl. ounces of liquid sealant per tire , 95 grams for each of the rubber maxxis rim strips. Most of the leaking when installing the tires (used a hand floor pump, worked fine), came from around the bead as it happens. Only had 2 or 3 leaks past the studs.

Boy, talk about a bumpy ride!

Should be interesting to see how well those octopus legs work. They look like they could scale a wall :)

Cheers,

Tommorow's the test ride (its -27C here today, tommorow's supposed to be -16) and saturday I got a race with them to do on ice (-7C).

ouch, that's cold! Well, I hope they work out for you and you win the race! Sounds like it should be fun :)

I'm guessing that those bottlecaps will all be flat as a pancake before you finish your test ride.

Doesn't matter if they are, there's #10-32 machine screws with nuts on the ends in the center of each cap. The caps are there only for cornering really. Lean the tire and its a nice sharp edge to dig into the ice. Besides which, you'd actually have to hit them with a hammer on a steel surface/concrete to flatten 'em. Simply standing on one, 170 pounds of weight, with just my heel wouldn't flatten it. It takes an awful lot of force to even bend a bottle cap. Simply prying one off a bottle with a bottle opener focuses a lot of energy into a very small cross section of the cap edge.

Post a follow-up on how they work. I'm curious. Must be nice to be able to race in this weather. Around here, our racing season ends in Spetember, which is right around the time that oppresssive summer heat is fading.

........left the bottles connected to the caps for an even more interesting ride. Bwaaa I break me up.

I thought you weren't coming to the new forums mikey?

Well the race went well, but I should have staggered the rear tires stud pattern also. Didn't have enough cornering grip and kept sliding the back end around (not helped by being 6'6" or riding a 21.5" size frame - high center of gravity). Lost about 20 nuts and therefore the caps under the nuts total (12 front, 8 back) over nine laps of the course (about a mile per lap) on a frozen lake. I did get myself interviewed by several local media groups for my innovative stud design at least.

Cool! Sounds like it was fun. Are you going to continue to "fine tune" the setup or let it go?

pic from the race, I had the most armor on I think but then I also seemed to do the most spectacular wipeouts from the speed I was carrying.

Fine tuning will likely involve switching to a staggered hybrid pattern for the rear tire but still leaving the machine screws in the center row, also I'm slowly going to switch to bottlecaps off bottles instead of brand new caps (for beer brewing and bottling) as they have a sharper edge to them. as the other ones get ripped off in usage.

I didn't say I wasn't coming Upey, I said I didn't like it. Neither have changed. I've probably been here as much as you have.

Too Funny! I wanna do a frozen lake race!
