• they make Mavic tyres too, replaced a badly punctured Hutchinson 11 storm with a mavic of the same spec for a lot cheaper.

  • Ive got a folded anchovy in there and it’s not fully sealing. It’s me tyre time or some sort of permanent fix. I can see the patches on previous page now so will try that.

  • What works best for me is patch and tubular glue. Latex will try to get under anything.

  • Ugh. Broke both darts on my Stan's tool. May as well have burned a £20 note. Still haven't fixed the hole. I guess that tire's coming off and bleargh.

  • For anyone interested in the Silca sealant (and replenisher) I have just changed tyres after several months using the Silca, and one dose of replenisher along the way.

    I’ve read a few posts elsewhere mentioning that this sealant damages rim tape and / or dries out.

    It certainly didn’t dry out (although was replenished, as per the Silca directions). Plenty sloshing about in there. Very little string formation. One substantial clump of sealant and fibres firmly attached inside each tyre, which fits the puncture history. And the rim tape seems fine.

    However - I am a bit concerned that there is a lot of wear along the inside centre of each tyre - a 1cm band around the periphery where the casing appears to be threadbare. I wonder if the carbon fibre particles in this stuff are perhaps a bit too abrasive?

  • Why would anyone want to have carbon particles in the sealant? Even old school glitter mix sounds like a lot better idea

  • Carbon fibres, I should have said. There surely must be better options energy / pollution-wise.

  • better options energy / pollution-wise

    Probably not, or people would already use them. The sort of short weak carbon fibres which work to clog holes in a tyre sealant can be made from biomass of various kinds, as the first carbon fibres were. Current efforts seem to centre around lignin, as vast amounts of waste lignin emerge from paper making.

  • There's nuts on the Panaracer sealant, or so they claimed. Not sure how that's good either. Some misterious fibrous thing that clogged valves in Stans Race, was actually pretty good.

  • I'm promising myself that I'm finally going to get round to setting my tyres up tubeless in the next couple of weeks. It'll be my first time dabbling. I've got a bog standard Joe Blow track pump and access to a Makita air compressor at work (pictured below). The air compressor takes about as long as a pump to inflate a tyre so it's not the quick blast of air that I reckon is needed to seat tubeless tyres. Are either likely to be up to the task or shall I save myself a headache and get something specifically designed for the task? I've got Vittoria Corsas I'm planning on using installed with tubes currently and they were an absolute bastard to get seated so I reckon the whole thing is going to be a colossal pain in the arse.

  • It'll depend on the tyre and rim combo, the inflater will leave you with two free hands to move the wheel around and maybe help things along by squeezing certain bits, but sometimes they need a decent amount of airflow that you might not be able to reach to get it started. Worth a try if you can leave it a while if you need to get more things, but if you want to be more certain in advance then you'll want some way of blasting a decent shot of air at once.

  • It might be worth taking a tube out and seeing if the tyre will seat using the track pump, with the valve core out, assuming the rim is taped. Be liberal with very soapy water on the beads.
    If it doesn’t, then you will know neither track pump nor compressor will work.
    If they don’t work then whichever you choose to use will need some sort of reserve tank to produce a blast.

    The idea being to get all this sorted before any sealant is involved.

  • very soapy water

    No, bare minimum of soap. You only need enough to break the tension so that the water wets the surfaces instead of beading up. You're lubricating, not washing, and it's the water which is the lubricant.

  • Thanks for all the tips. I'll have a punt with what I have first I reckon. I've got another bike that I can ride if it all goes tits up and I have to wait a few days for any additional equipment to arrive.

  • I'm yet to meet a combo that I haven't seated with a track pump, from MTB to road. Def have a punt.

    (Actually, I couldn't do it with a friends Maxxis Ramblers after acting the big man)

  • no soap water
    no sealant
    nothing but a track pump

    if you need anything else you have done something wrong, most likely tape

  • I've met plenty that have needed a compressor or similar to get going, but have had to do quite a few and I'm not going to grab a pump when I've got a compressor, also met a few that are a pain to seat properly without done lube, which is kinda the opposite problem.

  • stop meeting other people

  • But I need them for money.

  • Are you still in Penge? I've a Airshot you're welcome to borrow in Beckenham.

  • I got beaten by a downhill casing Magic Mary, twice. Both times I had to stick a tube in it overnight.

  • I've got Vittoria Corsas I'm planning on using installed with tubes currently

    If you have tubeless tape already remove just one side to get the tube out.
    And please do lube the beads with a bit of water, those tires are bastards to seat

  • Ghetto tubeless on the MTB. Seemed ok and been on one short ride. Left bike in the garage for a week and it's gone flat. Pumped up again ok. Is this normal? A case of sealant not getting everywhere? I was pretty diligent with the taping.

  • I’ve had a few wheels do this once and then never again, not long after fitting.

    Also some that seemed totally fine and then after not riding for ages would be totally empty (due to an unsealed puncture)

    I would just keep an eye on the sort of pressure it holds for the day, if it’s dropping 10psi over a couple of hours then it would be a problem on a ride and needs investigating
