    Mag wheel repair

    Can anyone recommend a good person/company to repair some leaky cracks I've found in a RS125 wheel (old Technomagnesio)?

    Thanks

    Arrow Wheels in Auckland is probably your best bet.

    Better to scrap it. Magnesium wheels don't last forever.

    I tend to agree. It should at least be stripped and crack tested - you may be surprised, but not in a good way...

    Lucky I didn't do that swap

    Go on lash out and get yourself a new set. Lighter, better and well better looking.

    No, but you NEED TO GET IT TESTED before you use it again. You do not wanting the wheel failing.

    Although I remember the wheel was carbon fiber the result is the same.

    Good luck with that repair.

    Been down this path..... Idiots who tried welding it up Didn't fix the crack heat even bent the rim by the looks when I got it back.

    Bike shop who said "Yeah we can fix it" as in we the bike shop then out sourced the job to a engineer firm who didn't say "Nah we don't know wtf we are doing.Found all this out when I returned to pick it up and bastards still had the cheek to charge me for the out work even though a fail!.

    I don't go there anymore.

    Bin it I say.You could end up chasing a broken tail when it would have been better buying a whole new tiger.

    We have welded magnesium bits.
    Its easy enough to do.
    You can get a tig filler rod for it.
    Problem with some of the alloys are micro porous & when you weld them the bubbles clump together to become bigger bubbles, & that's a big stress riser at 200k
    You can speak to Mike or Andrew Fisher at Xray Labs in Leonard Rd. Real clever & helpful guys.
    I would say they are proper fucked with fatigue
    Burn them & buy some carbon ones

    If they are beyond repair, bring them along to the next round and we will see if we can get a camp fire going

    This time don't go secondhand...On another forum I've seen pics of a front BST carbon on a Ducati which disintegrated at Eastern Creek last week.
    That one was secondhand and of unknown history....

    You lads raise some very good points. I wasn't going to put it back on my RS125, rather the bucket after being repaired. Unsure if that's even worth it after this.
    If you're at Mt Welly this weekend lets chat Darren

    poppycock, it was not carbon fibre, my memory was it was a marvic, they were changing the wheels at the pitstops and putting used slicks on, no need for new rubber at the tt then, they were worried about the wheels.

    Gee I always remember that as being a CF wheel, came straight to mind before I clicked the video that Dunlop proved HRC failed at cf wheels. Now I'd believe you are probably right and it was a rumour, but a popular one so perhaps leaving Jason reeling in the sting of a poppycock is unfair.
    That said the little cunt called me a peckerhead last week.
    Don't you look at my accountant.
    He's the only one I've got.

    True or not I distinctly remember CF wheels mentioned the first time I saw that incident. I remember it as CF wheels were a fairly new and unusual thing back in the vintage days....

    BTW that is Mr. little cunt to you.
