[#7398106]

well...

Tried every trick in the book to fit 2 different tyres...no joy. Eventutally devcided to take of the rim tape to try to give me a bit more room...

made a big difference, could almost put it on by hand...just needed a tiny bit of help with the tyre lever...didn't want to put much force on there....

almost there.......

then...

almost cried....

Bought second hand off here..I assume LB won't warrenty them without prrof of purchase. Whats my options. Repairable? Ridable? New rim....?

I should add that I'm not convinced that a wheel that I've spent around a week fitting a tyre fills me with much confidence for taking out on a winter 50 mile ride...but hey ho..

Might have crash replacement SRAM does for theirs. Email them they can only say no. Theyt look a bit dry? On putting tyres on m8 I lube them and the rims with a little stans. Helps a lot in letting the slide on and slide into place when pumping up. I can get my HR2 on my Roams by handwithout tools. If you see truck car tyres being changed they do the same with soap/water to let the tyre slip onto the rim

Applying pressure on the rim outwards isnt what its designed for, just holding a tyre on.

The lay up of the carbon on the rim dosent look right either (non expert opinion) what brand is that?

light bycycle rim...

The actual inside of the rim feels sturdy, no flex there atall, its just the outside that has delaminated Do you thnk carbon repair kit may work. Or some kind of strong epoxy to bond it back together?

Bit pissed really..there was no way on earth the tyre was going on without the lever.

That sucks. Is it a road rim? Looks very deep profile. The LB rims I had had the usual channel in the middle to aid with fitting the tyre, which yours don't appear to have.

Carbon is so strong structurally that people forget that at a point load it's only as strong as the resin or whatever that holds the carbon in place - a bit like chipping the corner off a concrete bridge stanchion with a well-aimed chisel blow then driving a truck at it.

Talc is the answer for tight tyres.

What tyres? Not wishing to teach you to suck eggs, but I'd be avoiding levers at all costs on a carbon rim (as I said on the other thread), but IME they're 100% unnecessary on LB rims.

they were giant tyres, but also tied a conti gp4000

As I mentioned the rim still appears sturdy, only the outer layers have delaminated. Ironically this only happened after I removed the overly thick rim tape

I'm tempted to superglue the delamintated pit together to stop it geeting any worse then trying to fit a tyre and just riding it..

back wheel btw...

folly...will I die?

On carbon rc glider bits if there was a reasonable structure I'd use thin super glue wicked into the area to stabilise it, cut back surface damage and then rebuild with resin and cloth or uni over a reasonable chamfered area. If it is 'just' the tyre retaining wall I would risk it. Maybe contact one of the carbon bike repair companies to see if they do rims.

Surrey Carbon Cycle Repair or whatever they're called in Dorking definitely do rims. May not be cost effective on a LB rim though. I'd be wary of any repair as its on the braking surface too.

When I bought some wheels, the rims were very tight and my usual race tyres, Michelin Pro's, just wouldn't fit on at all, I found Schwalbe were a slightly looser fit, so those are the tyres I now use.

As you've said, the last thing you want is to struggle to get tyres off in winter.
Take them down to your LBS and ask if you can try tyres out to see what make fit the easiest.

If you're going to give it go repairing it yourself, get a carbon repair kit (they're not expensive) because the resin is much strong than most stuff you can buy locally and you need that because its part of the braking surface and you don't want it pealing off.

Edit:
I see you're in Edinburgh, if you want, bring it to me and I'll have a look.

POSTED 1 HOUR AGO # REPORT-POST

Why is it fraud? If the product has X amount of years warranty and the product is within that period there is no problem.

Now if the product was out of warranty and someone produced a fake receipt to try and make out the product was newer than it actually was then that's fraud.

Getting the origonal owner to put a claim in is not.
