is my veloflex sprinter done for? i counted a total of 7 cuts and punctures.
Assuming that you manage to seal the inner tube, some of the cuts you can close with super glue.
Rubber damage from first pic will leave a weak point anyway. Then the L shape cut. It will be very hard to glue it. Even if you manage to do that, it will not withstand the pressure and ride itself. The cut is just too big and the caracas may also be compromised.
In the best case you will end up with the bulge in this place.
You can give it a go, but imo it will be a waste of your time.
And advice on the sealant, I ditched Pitstop after my first two attempts. It wasn't messy, but simply it didn't work.
I had a good experience with No tubes and Orange.
i've had veloflex tubs with way more cuts than that, as long as the tyre isn't bulging at a cut it's fine
with any cut that reaches the carcass, what tends to happen is it causes abrasion of the inner tube, eventually leading to a puncture, personally i would not put superglue in a cut, if it reaches the carcass it'll set it hard which is even more damaging to the inner tube
now that the tub has sealant in it, you need to avoid letting it deflate, if that happens the sealant can stick the inner tube to itself, then it'll fail when re-inflated
you can try putting some better sealant in and see if it holds, as long as there aren't bulges you can keep resealing if an old/new puncture opens up, sealants dry out over time, but if it's really worn it'll hole more easily and there comes a point where you could spend more on new sealant than the tyre is worth
with just a single puncture in a new/newish tub, i prefer to repair, but once it's worn i put sealant in as the return on time/effort is not so good if it's already worn,
I've actually had good experience with PitStop. It can't fix large punctures, but used correctly (hold the can on the valve for a full minute), I think it serves its purpose.
your picture shows 'endurance' orange seal, it's different - i made the same mistake once, only found out later i'd got the wrong typeaddictR1 wrote: ↑Wed May 23, 2018 3:25 amgot some orange seal today and filled about 2-3oz of it. spun it around for a while before pumping up. it squirted and wouldn't seal.
then saw on youtube ppl use crazy glue + patch. so i did that and so far it's holding at 125psi.... hopefully it will keep it sealed...
i think it is designed to stay liquid longer in tubeless applications before needing refill, but it does not seal as well when used to try and fix inner tubes
putting a patch on the outside may help by giving the sealant extra time/support while it dries in the hole, how it lasts out on the road will be the test, especially when hitting bumps
ordered some tufo extreme from chain reaction. any point in putting those in or just save it for next time i have a flat on a different veloflex?
My lbs recommended the endurance version because it states it’s for tubular, whereas the original orange seal doesn’t.
for the tub with the orange seal in it, i'd just see how it goes, eventually the sealant will dry out, then should be ok to put tufo in it if it flats again - about one third of a bottle is enough
with tufo, it seals anything that can be sealed - including it's own nozzle, presta valves, valve stems - i carry a bit of plastic coated wire to unclog the nozzle
In my experience, the best way to repair tubulars is to simply replace the tube. There are services that will do that for you. My personal recommendation would be to avoid sealants and the like for tubulars (althought I have been itching to try a can of Pitstop that I have been lugging-around for a long time now, just because). The 'enclosed' nature of the tubular 'environment' makes the use of such sealants less effective than in tubeless applications and causes a real mess for re-tubing later.
But speaking of embarrassing moments... yesterday I was bombing down a long very smooth relatively straight descent and noticed what seemed like a hop in my wheel but thought it was just uneven pavement. I eventually stopped to check and sure enough there was a hop in the tire, not the rim. Hmmm... that’s never happened before as I’m always really meticulous about my glue jobs. Eventually got home and left it for another day, this morning to be precise. Well, turns out that particular wheelset was not glued at all, I had just mounted some Veloflex on them as placeholders. So, I’ve had several rides now on those tires/wheels down some pretty fast curvy stretches that could have been disastrous had the tube came off. But it never did. Both front and rear, completely unglued, and here I am riding around on them up hill, downhill curves etc. There was some very light glue remaining on the rims from a previous four job but that’s it. Nothing on the tire at all and they both just peeled off easily once deflated. Now that I think back there were a couple of times recently that I recall the rear feeling a bit different, maybe a slight wobble, but never thought anything more of it till just now. And now that I think back some more, there was a set of wheels that I’d been meaning to glue but never got around to it. That’s because I mounted them in some rims and just put them on a bike to keep them out of the way for the time being. Ouch! And I’m really trying to stay injury free this year.
