lacing two rims to a single hub

[wasted weasel]

I saw a picture last summer but found no additional information about it, of a guy participating in some arctic bicycle race and it totally looked like he was running some sort of dual tire system in an extra wide front fork. I've haven't found much info regarding this method other than this site http://www.geocities.com/~bikerodnkustom/tech3.html.
Looks like you would need a custom frame to accept the wider tire/rims combo.... but winter is almost done in Toronto now, and I'll have all summer to fabricate something.

I'm still looking for more info if anyone know's of any other links (english or non english) that would be awsome.

HMM I dunno about that. Sun makes a "doublewide" inspired by events such as the Iditasport, that IMHO would function alot better than that.

The Snow Cat rim is sort of the original doublewide. Word has it that it started out as two rims bonded together and laced to a single hub but nowadays it's an actual product you can buy. Surly also has their Large Marge rim.

For tires I know Nokian makes a 3" tire specifically for this purpose and soon Surly will have their 3.7" rubber out.

There should be many bikes that can take a 3" tire though Surly is claiming that their upcoming Pugsley frame (due this summer along with the tires) will be the first that can accept a 4".

The Pugsley promises to be a pretty awesomely ugly (and expensive) bike when it finally lands on planet Earth.

Pugsley?What about a bike called Morticia or Gomez or Lurch?You rannnng?

what do the large marge rims cost?
they'd certainly be lighter, but.... for around a $100 total investment I'll experiment first and mod a cheap bike before dropping mega bucks on a Moots snow bike or a Pugsley (pink?? gross), or related snow specific parts.

I wouldn't mind something that I can ride through a foot of powder without loosing momentum, or cutting through and spinning

edit* haha it'd be my luck that'd I'd buy snow rims and tires this year and next winter we only see 4 inches of snow...

I just dont understand why buy these double rim wheels, it seems impractical to me. Just get a regular wide rim, imagine truing one of those monsters.

[bostontrevor]

The Large Marge seems to retail around $100 a shot, so it's not cheap but then nothing is going to let you ride through a foot of snow without losing momentum or sinking to the bottom. It's just a difference between hard and damn near impossible.

You get a doublewide because when you're looking at more than 5 inches of the white stuff, the options are to push through all of that or try to float on top.

It can and does. The tires are fat phat. The pink is not pepto-bismol pink. I recall it as more purple-ish actually.

Take a look at this website, it did have links and information about snow bike racing and snowcat double wide rims. It has changed a little, you may have to google to find the snowcat rims now.

Moots snowbike? When I toured the factory last summer and was caught drooling over said snowbike and not paying attention to the lecture on CNC ing stems I was told it was absolutely not for sale. I offered 'em $5K on the spot and they still said no. They figured it was at least a $10K investment. If they're selling snowbikes I'd like to know about it.
