Tubeless Larry

I’ve found a couple methods online to setup Pugsley wheels without tubes. Given how much a fat tire tube weighs and how much hassle it is to change a flat this could be a very sweet idea – especially for riding in thorn country!

I’m going to give this a shot with my Pugsley wheels as I rebuild the beast and see what happens.

I’ve considered looking into this here, but I’m thinking that I would have to change back to tubes for the winter months. It will be interesting to hear about how well they stay sealed at low pressures.

Guys over at MTBR are going to try tubeless in the winter and see what happens. Personally I’m not in a winter zone any more although I’m still going to riding sand and such which requires low pressures so we’ll see what happens. I’m going to mount my new Larry’s with tubes to stretch them out so the beads seal better than try tubeless.

In the 2007 Arrowhead 135, Charlie Farrow went with a tubeless set-up. He flatted six times in that race. That year we had temperatures down to -32F/-36C. Can’t even begin to imagine how he fixed that many flats in that kind of cold. And I was out there in the race that year.

At low tire pressures in extreme cold, even the people that use standard size tubes (26×2.5-2.7) to save weight rather than the large Surly tubes flatted more often.

Vik, it should be okay for your intended use, but others that plan on winter biking should be wary of going tubeless.

@Doug – good info. I’ve decided to run tubeless in my MTB first because I have it handy and can ride all Nov with it that way to see how it handles. I’ve never had a tubeless bike so it would be good to have some data on a “normal” bike before I try on the Pugs.

BTW – what a number of the guys are talking about for tubeless winter riding is to glue the split tube to the bead so it’s sealed. That may prevent the issues Charlie had. I certainly wouldn’t try it for the first time on a big event or tour!

Am doing the reckoning for a fat tyre bike – probably Moonlander with Big Fat Larries to do desert riding in Australia.

Any thoughts on going tubeless for that?

@bicycle nomad – tubeless has the advantage of less chance of getting flatted by thorns, but you’d want to carry tubes just in case so as not to get stranded. If you end up running extremely low pressures for soft sand you may have issues with a tubeless setup.

Given my limited experience with tubeless on a fat bike I wouldn’t recommend it for an expedition unless you have lots of time to trial it under similar, but less dangerous conditions.
