3 inch studs

Is there anyone that sells or makes 3 inch wide studded tires?

Widest off-the-shelf option is Nokian Freddies Revenz. 2.3"

Wider would have to be home-brewed.

Really. It seems like making a bigger tire would make sense for snow.

Depends. Under some conditions it helps to have narrow tires that can slice down the surface below. If the snow is too deep or too heavy to slice all the way through, then it helps to be able to float on top. My guess is that the slicing style is more useful to more people than the floating style.

jim

p.s., check out a Surly Pugley with Large Marge tires.

I'm in the south of the uk so only ride in snow once a winter if I'm lucky but I always thought studded tyres were more use for ice or frozen snow (where you would be stuck on top and it is effectively ice) than for riding in snow?

Yeah definitely. Knobs help in snow, studs on ice. You're gonna want to cut down to the ice. Look at a rally car - extremely narrow tires.

Or, look at bicycles designed for racing in snow - extremely wide tires.



Float FTW.

^^ On the front tire... What is opposite the disk brake? Looks like it is dual disk brake, but it almost looks like additional gears?

Just curious.

Is it a 2-wheel drive bike?


Edit: I know they exist, but I can't see how that set of gears would work without a chain...

Haha- Partially my question!

I just don't know what it is... To me it looks like either a second disk brake or a random set of gears that are not connected to a chain.

I just don't know!

the fork probably has the same hub spacing as the rear. The Surly Pugsley has the same thing, where you have the option of using 2 different casettes and flipping the wheels from back to front if you require different gear ratios.

So what I am seeing could very well be an extra (random) set of gears?!?! What a great idea! Same concept as the flip-flop hub for single speed/ fixed gear, but taken to a new level.

Way cool. Thanks for the clarification!

I wish I could play on the snow with my bike. Fixed gear with studded tires on snow/ice--
challenge.

Winter here means inversion and bad air quality with temperatures that would the daily high in some
parts of the country.

This is a survival bike. The front wheel is designed to be interchangable with the rear in case of damage to the rear cassette or hub. Which if your stranded hundreds of frozen miles from civilization could mean your life.

I remember reading about that bike. They made the front fork a pressure vessel to store LPG or other fuels for fires.

rear: chain
front: hydraulic pump engages front wheel when the rear wheel slips and causes extra power to be diverted to the hydraulic pump.

somewhat impractical for a bike, but not impossible
