Hello!
Just in case anyone is interested in converting to tubeless, but hasn’t yet taken the plunge, I thought I’d share my experience. If you’re already a seasoned tubeless rider, then I apologise, and you can move on to another post with no shame, or alternatively add your tuppen’worth of experience below.
To put it into context, I am commuting on a full-sus eMTB. My route is a combination of canal towpaths, which vary from almost asphalt to single-track and mud. These invariably have hawthorn hedges next to them, which cause inevitable problems when they are cut which tends to happen in the winter. I therefore get lots of thorn punctures and on one ride a few years ago I stopped to fix one and actually had five! So that bike got some Schwalbe Marathons and I haven’t had a puncture on it since. I have had the same experience with my gravel bike, and once again I have improved my boots. So far so good.
So this new ebike needed something doing, as on one in three rides so far I have had a thorn puncture. This weekend I took the plunge, and got hold of some of the liquid gunk from Amazon and had a go at doing it myself. I watched quite a few youtube vids of people doing it, and the best were from GMBN. All pretty straightforward.
I’ll not go into full detail here apart from pointing out a few things which may help if you’re new to this like me, and want to avoid too many errors.
Firstly, my rims and tyres were already set up for tubeless when I got the bike, and there were a couple of valves plus spare rim tape (which I didn’t use) in the box. I therefore only needed the gunk. I chose Muc-Off as I like the smell! I poured it straight in to the tyre rather than using a syringe and had no problems with this, although the potential for mess is definitely there!
Secondly, one of the wheels went on fine and sealed straight away. I used a CO2 cylinder to pop the tyre onto the rim initially and then a track pump to get it up to 40psi.
Thirdly, the rear tyre was much more of a problem as I had air leaking around the valve stem. On further research, this seems to normally happen when the rim tape is not sealing properly, apparently, and after a few tries to pump it up and see whether the gunk would seal any gaps, I gave up and started again.
This was a messy old business, but nothing fatal - unless you are a roll of kitchen towel, in which case it was utter carnage. Once all cleaned up I examined my rim tape again, and there was a small scuffed patch / hole in it where I think I’d caught it with a metal tyre lever during a previous tube puncture repair. The rim itself showed some scratches next to it too. I’m using plastic tyre levers now. To cover this, I stuck a 30cm x 25mm strip of Gorilla tape over the top of the rim tape, 15cm eaither side of the worrisome patch.
I also gave a couple of quarter tightens to the valve collar thing with pliers, too, to improve the seal there. When I pumped it all up again (I did a dry run first because I’m learning fast!) this leak had gone. Then did the final gunk-fill and inflate. 8 hours later plus a couple of miles round the lanes, and it is still up. Result!
So apart from a bit of mess and subsequent cleaning up, I can say it was a success, and if you are a newbie to all of this and somewhat intimidated by tubeless, then don’t be, and give it a go.
Cheers!
Si.
