Backup Tube for Tubless

[Chew]

So moved to the world of tubeless on the new bike.

Fingers crossed no punctures next week. What do people use as a get you home tube. Full 29er tube/26er tube/700c tube?

[composite]

Depends on the size of the wheel?

[Chew]

Sorry 29er wheels

[composite]

A 29er tube then. Although if you already have 26/650B knocking round then they will do the job to get you home.

[Dyffers]

Spare 29er tube & patches for days out away from civilisation, but I've stopped carrying anything other than a tubeless sewing kit and pump for local rides as my tyres have so many sealed thorns in them that a tube punctures straight away.

This is a real problem. I carry a small pair of pliers in my tool kit anyway which I use to pull out thorns.

I just use the smallest allen key on my multi tool, and push them out from the outside, does the job, saves carrying pliers!

I'm also going to invest in some Tubeless worms, have heard good things about them.

[Dave Barter]

Tubeless worms are the business. I use the Weldite kit which is surprisingly hard to get, lbs has never heard of it. One of my tyres has 4 worms in it and still going strong including one in the sidewall. So easy to fix a puncture and no wheel removal needed

[mountainbaker]

Thanks Dave, JE James have them in, I've ordered some.

saves carrying pliers!

I also need the pliers to be able to pull the split pin to change my brake pads.

[mountainbaker]

Really?

I use my fingers and flathead screwdriver for Hope ones. Not sure if they are the same on Shimano. To be fair, I don't even have a pin on my front brake, it's been missing for ages.

How do they stay in?

[mountainbaker]

The hope ones thread into the body, then there's a pin on the other side to stop it falling out if it unthreads. It's never come loose yet, so I'm not concerned.

[Zippy]

Oh sorry, that pin, not the main pin, I'm with you now!

[FLV]

I carry a superlight conti or Swalbe 29er tube, and some instant patches.
For longer trips, 2 tubes.

It's less of an issue with thorns round here than some places though

The main pin on the shimano deore are a split pin, no thread like on the Hope. As such they are rather more difficult to remove.

I was told that you can use a 26 inch tube in a 29 inch tyre, and I suspect with some tyre/rim combos you can, but I faffed around for ages trying to get the tyre back on the rim without pinching the tube. Using a 29inch tube was much easier. Gas or pump? That's my conundrum.

[VeganGraham]

I always carry a spare tube, or two on a long ride.
A couple of times I've had a big hole in a tyre and it's gone completely flat before I've had time to get the plugs out and stick one in.
If you can't reseat the tyre with a hand pump and you've got no tube, you're in trouble.

[mountainbaker]

Gas or pump? That's my conundrum.

When Andy (ChickenLegs) and I did the South Downs Double last month, Andy punctured, put a tube in, gassed the tube, and wham, he got a pinch flat. I'm not sure if that had anything to do with the fast inflation, or just bad tube placement. But I would just use a decent (and small pump).

[Alpinum]

I use 26" Latex tubes for all of my bikes, 26 or 29" (oh, except the fat bike that is).

Sounds a bit like the tube got jammed between the rim and tyre...?
I use Gas for time critical trips (enduro stuff) and pump for everything else.
But I think I over did weight saving with my 55 g toppeak pump. It takes 700(!) strokes to put about 2.0 bar into a 29 x 2.4" tyre...
There are pumps that'll pump the same tyre with 200 strokes weighing in at 90 g.

I can remember watching Gareth trying to put air back into his tyre on a climb outside Ullapool. He was swearing for 10 min doing so. I smoked fag and laughed. Then thought of him again, when I had to fix a puncture myself... some small pumps can certainly drive you nuts.

That was very funny. I laughed a lot too!

Yep, that's what happened. Don't think he'll do it again!
