Gash in new tubular tyre: fix or replace?

Posted on
  • I've recently gone tubular with a set of new Campy Bora's (tub version of the Bora's being 200g lighter and £200 cheaper than clinchers - 'so why on earth not' I thought to myself)

    Yes, I do now regret that decision

    Anyway, on my second ride I managed to get a 3/4 cm gash on the top side of the rear tyre (it held full psi on way home, it was fine, but when the next day I added some extra air it went bang)

    Is this repairable or am I gonna have to fork out for a new £70 Vittoria Corsa G+ tyre?

    I dread to think that owning these wheels - which I couldn't afford in the 1st place - are going to cost me £100 pm maintenance. My own stupid fault, I guess. And to think the GP4000's on my other bike can, and will, go for 1000's of miles without so much as a slow puncture.

  • Sounds like you were pretty unlucky.

    Can you fix that tub? Maybe - but it sounds like it died a violent death.

    Chuck some slightly more robust tubs on and I bet you'll be fine for 1000's miles.

    BTW there's a tub thread :)

  • I can't seem to find the tub thread, could you send me a link? Ta

  • Thanks

  • ive repaired a few Corsa Gs for mates, they arent any different to open up than previous corsa tubs although im not so keen on repairing latex innertubes and sod re-tubing one. The thing with latex innertubes is that even if the object that cuts the tyre doesnt initially puncture the tube it is so thin and stretchy it will expand into a very small hole with the pressure and blowout. In the same way you would boot a clincher tyre you can reinforce the cut area by putting various things between the innertube and tyre carcass although on this occasion it sounds as though its too big a cut to bother. The Gs are just way too fragile for daily use- despite all the talk of graphene i have found it make little difference and as for the rubber compound.. freshly chipped road will destroy them . A friend has DNF 3 races with punctures using the speed versions so i would recommend something tougher. Ive always gone with conti sprinters - ok they carry a weight penalty and are not as supple as vittorias but on the plus side they dont seem to cut up so easily.

  • Thanks, that's really great advice.

    Would you go with Continental Sprinter Gatorskin or just the Continental Sprinter

    I'll buy them now....and maybe practice playing around with repairing the gashed Corsa G+ and remove the undamaged one from the front wheel and use it as a spare, perhaps? Would that be OK, to use an old (well ALMOST new in this case) as a spare when out on long rides?

    Thanks again

  • Sell tubular wheels, and go for a tubeless wheelset.

  • Gatorskins are goood but don't feel so much like a tub. I'd go for the sprinter.

  • Nice idea, it will be a hassle but I'll certainly look into it.

    Maybe I'll mothball them for a while so that they retain their sheen. Then again, given that they're so nice to ride, that will prove a challenge.

    And they do look the dogs proverbials it must be said, especially in the 'dark label'. Oh and my god they sound amazing too!

  • OK, will purchase now. Thx

  • Just a small thought - I would never carry a spare tire / tube that is more delicate than the one that is being replaced. Ride the front one until it dies and keep a sprinter (or something more durable still) to make sure you get home if needed

  • If I retain the good front Corsa G+ shouldn't I therefore replace the rear with the same tyre?

    I really don't like the idea of having 2 different tyres!

    Is it legit to have two completely different tyres?

    Dear dilemma!


  • Oh! I must admit I hadn't really considered that. I haven't had any nice wheels for a while and the only bike I have that would do justice to them lives in a shed in Suffolk! So that concern had slipped my mind.

    I suspect as others have said that its just really bad luck on the Corsa, so yeah maybe swap it and save it for next summer if you're still happy with the wheels

  • I guess I'll be really old fashioned and take the wheel with tyre into my lbs this lunch time. Maybe they can do a repair. If they can great, but, if not then I have 2 new Conti Sprinters on the way.

  • I had the same set up - Bora tubulars (Bora One in my case) with Corsa G+. They are absolutely lovely tyres but a bit fragile for everyday riding.

    Now have Conti sprinters with a bit of sealant in after the front and rear succumbed to cuts. They're not as plush feeling but no flats so far.

    For racing later in the year, I may switch back.

  • @Rambino there are specialists that do repair tubulars which might well be worth it since it's so early in it's life.

    I've been happy with Veloflex Roubaix so far although only in the dry and racing, they have made it through London glass strewn roads a few times.

  • I do them at a rate of first one free then £10 a repair for team mates as i can normally turn one round within an hour. There used to be a lot of repairers and it was even possible to get them retreaded, less so these days.

  • Hey guys

    I've just found this guy:

    Just dropped him an email to see what he thinks.

    Still waiting for a response, I'll let you know how it goes

    Photo below for you guys to decide.

  • a quick patch on the inside of the tub and some superglue that doesnt set too firm would sort it.

  • Tub now in the post

    Garry, the guy who runs the tub fix website seems fairly confident he can fix it.

    It's cost me £12 for the repair + £5 for his return postage costs.

    So 17 quid all in seems like a good deal to me. Also, as an added bonus, if he deems the tub to be unrepeatable, you'll get a full refund.


  • Sounds like a good plan....

  • Are Conti Competition still the favoured Conti tub in the pro peloton? Probably a good balance between performance and durability.

  • the pro ltd are, ive never had one so i cannot say what theyre like although it seems the change was to fit a latex tube inside. The old competitions are the hardest tub to fit, its like someone in the factory put the wrong dimension into the machine. Thumb breakers on some rims although its kind of reassuring to know they cannot roll off easily.

  • Heh, I suppose the pros don't need to worry about changing tubs and puncture = new wheel from the team car.
