A mirror for the bathroom?

Hi,

Corima (Serval-France) can quite probably repair that rim even though it's not gonna be easy to reproduce such a large part of the brake track...
Buying a spare Bora rim is pretty much akin to wishful thinking.
It'll likely cost as much as a new wheel anyhow.

Before you junk that rim, I'd love you send me the stickers though....Mine are showing to many signs of warrior stress.

Ciao,

I rode with a pro this weekend. His team has been racing Boras this year. He & another guy have been breaking the wheels off & on. I ride Boras, I love my Boras, they have been great for me. They aren't unbreakable. They re lightweight racing parts that will break under the worst of stresses. I'd personally look for a new racing wheel. Have a Carbon expert look at & repair that wheel if you like. I just don't know If I'd want to risk my well being racing on it. Good Luck!

This is the perfect time to undertake another home project. Build something useful out of that thing, a table or mirror are epic ideas. Or do something useless like a wind chime. My vote goes to the table though, nothing like a class table with an aero carbon rim for the edge. Or send it to me and I'll make myself a table out of it. I could use a coffee table for my couch downstairs.

I'm a bit confused. Lots of people on the forum say that I should replace the rim. And I also think this is the safest option. I don't what to risk a crash and hurt myself or anyone else.

But on the other hand some say that this kind of damage is repairable. I contacted 4 different persons or companies who work with carbon composites, including forummember Samu Ilonen. And they also say that it's no problem to repair the rim. They are the experts and should know what they are talking about, no? Or are they just want to make money?

Who of you guys have actually experience with repairing carbon parts or have repaired carbon parts?

Replacing the rim will mean that I would replace the whole rear wheel since spare bora rims are hard to get. And that is going to be expensive. I know that if you can't replace it, you better not race it. I can replace it, but I only what to make sure it's the only right option, since it's ten times more expensive.

I think that the wheel should not be used in its current form for sure, though not because the rim is no longer structurally able to bear the load of riding. Although you could probably get a decent glue job down for casual riding, there would still be a place on the rim where the tire would be predisposed to rolling-off. Your safety and the safety of other riders is more important.

I have heard of rims being repaired before, usually in relation to a crack in the side of a deep-section wheel. As the rim bed and 'bead' area is principally to provide a surface on which to secure the tire (although it also serves a structural role, I believe that the rim could be repaired.

With respect to glue jobs, as a Junior I once (once!) rode a rear wheel glued by a shop mechanic. I learned my lesson in my first race on that wheel. In 20-plus years since, I have always glued my own tires and have never had one roll since.

Hi,

The company I mentioned before, Serval, does all the after sales repair for Corima wheels but will accept other manufacturers' wheels just the same.

I hope you read a little french as well as them some english but here goes :

I'm sure if you mail them some pics and ask them what they think of it you'd have a better idea of how to proceed.
One advantage of using an established company is that they guarantee their work. I.o.w they're liable.

Ciao,

Simply replace the rim with a pre-2008 Gigantex rim without the 'lava-dust' and get the stickers off that guy in Brazil that 'does the stickers' - Hey Presto! - same as before! Only £150 ($300) all-in.

You will be able to use the same spokes too

I had a fellow racing friend brake his carbon top tube in half. He sent the frame to Samu Ilonen and got it back in no time. He said the bike felt even stiffer then before. I would repair the rim! Good luck

As you said Samu is a professional. He knows what his doing! If you cant trust him then you cant trust anyone.

It wont be that expensive and if you have any doubts you can always use them for training.

If you want to have a go at repairing the damage yourself, i've used a company called Carbonology several times for my carbon fibre supplies. They even do a carbon fibre bicycle frame repair kit now for a reasonable price which will allow you to repair the rim damage without having to know what to buy and would easily be enough to repair the rim for less than £50 at a guess.

With the Bora rim, I would try and get a section of carbon fibre cloth with the same weave size and pattern, that way, you can splice it in to line up with the existing carbon pattern and you shouldn't notice the rim has been repaired unless on very close inspection.

In many respects, repairing that Bora rim is so much easier than trying to repair a tubular frame.


As I said in my earlier post, my offer of $100 for the rim still stands if you don't go for a repair or coffee table.[/quote]

I crashed my campag hyperon and my front wheel looked exactly like yours. I got hold of a guy in Norwich called Mike Burrows, who is known as the godfather of carbon fibre - i cant remember the name of his company but if you google his name you should find him - anyway he repaired it and it was perfect, you couldnt tell where the damage had previously been, cost me 50 quid, amazin value.

Also in Norwich is HQ Fibre Products. They were the people who actually made Boardman's Lotus bike.

As I said, to repair that rim is a an easy job for guys like that. Should be quick too. I've seen a frame snapped completely in half come out of HQ Fibre Products repaired and then be time trialled the following weekend and for another 3 seasons after that.

I've got the rim repaired. And I think that the person who did the repair, did a good job. If you know where the damage was, you can spot it. But if you didn't knew it, you wouldn't notice it. If anyone is interested I can post some pictures of the repair. I glued a tube on, but haven't ridden it yet.

Let's see

Yes, Please post a pic and let us know how it rides and if the braking surface is still even. How true does it look?
