Partial rolled tubular...how to reglue?

I rolled maybe 8 inches of my tubular Grifo last weekend, and was wondering how to repair this. There is still glue on the rim and tire, and I just hammered the tire back onto the rim and finished the race. I'm thinking I could just clean the exposed area a touch, and reapply some more Mastik and be ok, but figure I should get some more opinions on this.

My repair guy said to use Tubasti since it's so sticky/snotty. I then read that you shouldn't combine glues on the same wheel, which I can see the point of that as well.

Any thoughts?

Question is, why did it roll? If it was because it wasn't glued on well then you should start over. If it was because of a crash, something that would rip a clincher off for example (I've done this), then you can probably just brush and glob some glue in there.

Actually come to think of it, just start over

I'm not sure, but I think that I went airborne and then landed on the front wheel at a less than optimal trajectory, so the crash probably caused it. I'm going to check the rest of the glue job on the tire and go from there.

I see on one hand, that if the glue job was spotty and caused it to fail, then the whole glue job would be crappy. OTOH, if the crash caused it, then the glue job on the other 80% of the wheel is just fine.

You all are probably right, just to rip it off and reglue. That would be the smart play. I'll let you know which way I go.

So you are going to have glue and wheel in hand but want to risk possibly rolling another tire in a race. Spend the little extra time and fix it properly. Having confidence in your equipment is valuable in a race.

Well if it is really glued on well, you can see a nice glue squeeze out line along the glue joint around the whole rim and it is hard to peel off then you may be better off just touching it up. Reason being, if it's glued on really well you risk pulling the base tape off and then that has to be repaired.

I'm not sure what I'd do in that situation.

Stick it b sack on air it up and do a safety check on the non rolled section, you will quickly know what to do .

Just an update: I ended up just fixing the section that came off. It ran great for another 5-6 races, and I've pulled it off for road season now.
