• You will always have a gap when the rims starts to curve, this is not where the air seal is made. IF you have a leak, then the valve needs to be tighter pressed into the rim, so that the sealant creates a seal that doesn't move.

  • Ok, thanks, I'll investigate further

  • Get a pair of pliers and tighten it as much as you can. Once you have a seal, you can back it off. But remember to do this before you realise on a cold December day where you've barely any feeling left in your fingers and you don't have any pliers with you.

    Ask me how I know this.

  • One of the best products Giant make are these little washers . I hate the feeling of tightening those little nuts down onto the curved rim surface, I now have these washers on almost all my wheels.

  • Tubeless
    "tighten valve nut as much as you can"

    Also tubeless
    "don't overtighten the valve nut"

  • that's the thing :) as @andyp said. you tighten it to get a tight fit at the valve base and a good seal, but let it loose after that so you it doesn't get stuck overtime.
    tubeless is great

  • Anyone in N London have a compressor with a Presta fitting? Would like to put on some new 40x700 tyres fuss-free and I haven't got access to one anymore.

  • Have you not done the “cut the top off a valve cap trick” then down to the garage?

  • interesting, I reckon I can 3d print something very similar

  • I built an inflator out of a couple of old tubes, hose and a lemonade bottle. It actually fucking worked too.

  • This cursed image induced flashbacks to the abject horror of enduring ceaseless soapbar hot knives in my mate's kitchen in 1998...

  • Burned a new hole in my tracksuit today,
    Smoking Soap Bar without an ashtray,
    Red-hot nylon dripping on my skin,
    I ripped the fucker off, and threw it in the bin,
    Soap Bar’s cheap, and so’s my clothes,
    They’ve got to be cause of all the fucking holes,
    It tastes like shit and it makes you cough,
    And it’s the fucking rubber in it that gets you off.

    Yeah, I smoke Soap Bar with lots of bits of plastic,
    I leaves mine in it cause it tastes fantastic,
    Skunk costs too much, I can’t see the appeal,
    Of smoking Port Rocky, Soap Bar or Gold Seal,
    Smoke Rocky in a bong, bucket or hot-knives,
    Bake it in a cake for your Mam as a surprise,
    I smokes Green, and it’s gone in an instant,
    But Soap Bar lasts, cause it’s fucking consistent.

    Smoking on up, Soap Bar in the sky,
    I’ll smoke Soap Bar ‘till I fucking die,
    Before I die and they lay me to rest,
    I will always smoke Soap Bar, that’s the best.

    Last night I went out driving in my car,
    I sparked up a fat spliff of fucking Soap Bar,
    A Blim-burn burned right down to my dick,
    And while I was distracted, I fucking crashed into a
    Brick wall, the car was fucking battered,
    The bonnet flipped up and the windscreen shattered,
    You’re better off smoking The Green instead,
    Cause it don’t Blim-Burn and it’s better for your head.

    Soap Bar! Sitting in a deep sweat,
    Thinking! I’ve got to get some Rocky for the,
    Weekend! The sight of Draw excites me,
    Stick it in a bong, light it up and chug a fucking,
    Whitey! Burning holes in my tracky,
    This shit always happens when I’m smoking fucking Rocky,
    You’ve heard it on the news; you’ve seen it on the telly,
    Add up for moving Soap Bar down fucking Liz Werry
    “I do it like a little cause light the fucking thing as always”
    I used to smoke Skunky but it was far too smelly, man!

    Smoking on up, Soap Bar in the sky,
    I’ll smoke Soap Bar ‘till I fucking die,
    Before I die and they lay me to rest,
    I will always smoke Soap Bar, that’s the best.

    Most Soap Bar comes from fucking Holland,
    They make it out of oil, and tires and pollen,
    Diesel, Miramar, Flat-Press too;
    These are types of Soap Bar available to you,
    These little bits of plastic you find inside;
    You can use those as a quality guide,
    Of the standard of Soap Bar that you are smoking,
    The more bits of plastic means the better the toking.

    Eat a Hash-cake but wait a while,
    It’ll take about an hour ain’t Draw versatile,
    You can burn it, eat it, or smoke it in a spliff,
    Space shakes, Draw gateau’s, you knows it Delia Smith,
    Lying in your bed dropping blimps on your pubes,
    Selling Draw to your mates but it’s really Oxo cubes,
    When you’re cooking up draw, be quick don’t lick it,
    Cause it’s really fucking hot and it’ll burn your fingers.

    This bloke said to me; “You haven’t got a clue,
    About the damage that Soap Bar can do to you”,
    I tried to see things from his point of view,
    But I couldn’t fit my head up his asshole too,
    The bloke was wrong, I knows my stuff,
    I knows if I smoke it, I’m gonna feel rough,
    My lungs are fucked and my throat is raw,
    Cause the thing about Soap Bar; it’s fucking hardcore.

    Smoking on up, Soap Bar in the sky,
    I’ll smoke Soap Bar ‘till I fucking die,
    Before I die and they lay me to rest,
    I will always smoke Soap Bar, that’s the best.

    Well anyway I think it’s better myself to lean forwards,
    When smoking Soap Bar, because you are less likely to Blim-Burn,
    You know what I mean?

    Innit, check it out man! I got some quality fucking Gold-Seal for you, innit?

    Shape up all those little bits of plastic what you find inside, right,
    And then fucking stick them in a teapot,
    Makes a lovely cup of tea, that does.

    What I do, stick a fag in the microwave, right,
    You toke it up, you sticks the Draw on top,
    And you rams it in a bong and you rams the bong in your fucking head.

    Yeah that’s like my fucking lungs feel like,
    They’re fucking collapsing sometimes from the Soap Bar like,
    You know?

  • Looking carefully there is no front derailleur.

    I strongly suspect this is Ventoux?

    Lowkey boast post as you young people say

  • Check out my insta as the young people say for my real boast post


  • Coolest bit of DIY I've seen in a while! What pressure will it hold? What pressure fittings did you use?

  • I had one that I wrapped in gaffa tape to increase the strength a bit and it easily held 150psi. Two old valves stuck through the lid with a bit of epoxy and a 5mm i.d. hose of your choice, zip-tied on to one of the valves (with valve core removed). It helps to have a third had to kink the exit hose until you want to release the blast. That way it's someone else's head next to the tire too. ;)

  • Epoxied valves cut off from old tubes?

  • At least one of them needs to have the valve removed, so as long as they're tubes with removable valve cores, go for it.

  • My neighbour happens to have one of these

    and it worked a treat. The key bit was to get as much of the tyre bead as possible out of the rim centre channel (and especially around the valve) using a tyre lever.

  • Has anyone had issues with speed wobble due to sealant and centrifugal force (or whatever is actually happening).

    In Bosnia/Montenegro right now with my partner, Cinturato H 40 and 45mm tyre respectively, fresh sealant. I think about 60ml per tyre but maybe more.

    Front racks (jack the rack) and I have fork mounted bags but have ridden the same setup before with no issues. Checked both headsets and ridden both bikes with no load on front rack, but still getting shit front handling/speed wobble. My. Girlfriend described it as just suddenly happening and then stopping, I assume due to speed/vibration etc.

  • Nah, that's definitely the bags, not the sealant. Even if you've had the same setup before, a slight difference in weight distribution can change a lot.

  • That was my thought, but my girlfriend has a very stable Croix De Fer, just the empty rack on the front and she instantly said the handling had changed. The wheelset and tyres was new so could be a factor, but still 700c and very similar tyre width.

    Edit, it changed at certain times, not just different/worse the whole time.

  • Panaracer Gravel King slick (650B, 47mm) delaminated on the inside, filling with air and sealant between the layers and warping the tyre such that it started rubbing the frame. Quite sketchy. Apparently other people have experienced the same and it should be covered by warranty, but return postage costs nearly as much as the tyre itself.

    Back to 700c and Marathon Supremes...

  • Might be a solid lump of jizz . On smooth tarmac i have noticed a ump ump ump. I don't know a solution apart from stripping and new latex.
