As title - just a little bit tighter proved to tight and there was that sickening feeling as the torx key starts to spin.

Sooooo - what next can I do? cut a slightly bigger thread? Bung in a load of 'glue' and hope?

Get new rear 24 hole hub - Does anybody make a strong 24 hole rear hub I could lace to the Easton rim?

Oh and yes buy a torque wrench has just been added to my to do list ๐Ÿ™

thank you for abuse and suggestions

run the rotor with 5 bolts and don't screw the others up.

I really wouldn't worry about it - you've got five more bolts holding the rotor on.

If you want a bolt in there, then, yes, just cut a new thread and use a larger bolt/thread. There may not be enough material on the hub's bolt mounts to safely fit a Helicoil.

Googled helicoil - lots of sizes! Anybody done this and can point me to a specific kit???

Looks like a good option - I'm tempted just to run it with 5....

Just run it with five bolts, a few years ago a run my downhill bike with only 3 bolts in both hubs and it was fine.

I've run 5 before and it was easily fine.

in fact, a cheap lightening technique ๐Ÿ™„

Take another 2 out and run with 3, loctite in, problem solved, good enough for Peaty on his World Championship bike

I've repaired frames, derailleur hangers and lots of drum kit hardware using thread repair kits and have always bought the actualy Helicoil (brand name) kits. They come with everything you need (plus more) apart from the drill and tap holder. As I said above, though, you need to be sure that there's enough material on the hub's bolt mounts to safely fit a thread repair.

I still reckon you'll be fine with just five bolts.

FFS - fitting a helicoil removes less material than cutting for the next size up bolt - which would also mean drilling out the disc and probably grinding the larger head off the bolt as clearances are often tight. ๐Ÿ™„

You can bodge it - or you can make the proper repair which is to fit a helicoil.

YOur best bet would be to take it to an engineering shop or bike shop to get the helicoil fitted. to save the cost of the kit.

I use [url= http://www.recoilshop.net/?gclid=CKXwpsC6xKkCFUEa4QodgGMCEQ ]recoil kits as they are cheap from my local engineering shop[/url] and come with everything you need

Cheers all - Going for the lightweight option in the short term and will research the helicoil option for a proper fix

thansk!

well you keep giving utterly stupid advice about mechanics - that being one of the most stupid examples.

Must be awful being you. I hope we meet some day; I think that I would rather enjoy myself.

how about speaking to easton, maybe they'll fix ๐Ÿ˜‰

And also, get yourself a torque wrench. Should stop this for in the future.

UI did the same thing about a year ago on a pair of DT Swiss FR2350 wheels. Was gutted but have run with 5 ever since and never had a problem.

Steve Peat went through a phase of riding his DH bike with 3 Ti bolts holding each rotor on (weightsaving) so if he can do it then I'm sure you'll be fine with 5 bolts... ๐Ÿ™‚
