Discussion
Been looking to invest in some tubular zipps for a while and keep hearing how difficult they are to repair whilst out on the road etc etc.
However, i am curious as to whether a puncture on a tubular wheel (as opposed to a clincher)can be fixed on a temp basis using the sealant repair kits (spay foam inside the wheel) that i would normally carry around with me anyway.
Thoughts/experiences appreciated
Thanks CAB

hi,
if you mean olde-worlde glue-on tubulars and not the latest tubeless tyre systems, then puncture repair by the roadside isn't practical. I've tried one sealant with mine, the sort that was designed to be in place and fix punctures as they happened. The first time I knew it was there was when it started spraying out !
I don't know if the "inject when you puncture" type of sealant will be any better, but one thing to consider is that a clincher or tubular is at much higher pressure than a car or MTB tyre, and that's why I never bothered again.
I ride tubs in the summer and usually carry a spare rolled up under the saddle. Generally speaking I can change a tub quicker than I can replace the inner tube on clinchers, so it's only a problem if you puncture twice !

work on a tub... i can see no reason why not!
Has worked to very good effect on my MTB and commuter..

There are various 'lightweight' gloops available that you can use in tubs, but I tend to carry a spare tub instead: Tufo ones fold up nice and small. I carry tub tape, too, just in case what's on there comes off with the old tub.
I haven't done a long race on them yet, but for IM I'll carry two spare tubs plus the tape - and ride on triathlon-specific tyres to begin with: ie race-weight rubber with training tyre puncture protection.
Part of me thinks I'd be better-off sticking with clinchers, but the tubular wheels came with the bike and no way can I justify replacing them.

Plan to do a few competitive rides and in my mind any benefit derived from lighter tubs would be offset by;
- addittional tyres
- time taken to have to replace them....
which is why i am hoping the sealant would prove an effective solution. At the moment on my mtb i only ever bother taking 1* inner tube (for a bad rip) and a can of sealant...

For road racing, TTs and crits, tubs are the way to go - lighter and cheaper - if you puncture it is game over anyway - you are never getting back on if the group is moving semi quick, and 5 mins on your TT time is potentially huge.
For Tri's i would say go with clinchers - you are more likley to try to repair the flat rather than just abandon the race, due to the length and cost of most tris.
