carbon fibre spikes...

[James Cantle]

hey all.

 

i brought carbon fibre spikes last year and thought they was the bees knees until they fell apart:mad1:

where the heel attachment to the brace is has dropped down so when i spike the bottoms fall out. no good what so ever.

 

anybody else had this problem?

 

anyway u can maybe fix these so they stay in the right place

I just zip tied mine in place, this fix doesn't last long, but zip ties are cheap and easy to come by.

Stupid idea though glueing fabric to a smooth surface then expect it to stay there, should of been screwed in place..

[James Cantle]

i tried zip tying mine but eventually they just either broke or slipped down. using glue was a pretty silly idea.

 

do you think it would be ok to drill through the carbon fibre carefully and making your own hole?

[MasterBlaster]

I would do it.

Have you got a good bike shop nearby - they have to cut carbon seat posts for modern bikes, so will have top tips on working with the stuff. I know that gluing carbon is a tricky job, my mate had 2 returns on carbon bike frames 'cos the gluing hadn't taken properly, not so hot on a £2000 bike!.

 

Drilling it - would prob work, I'd be tempted to glue the bolt in to help any delamination later - but hey I'm farm from an expert!

Which carbon fibre spikes are we talking about guys?! (geckos?)

Mine have done exactly the same thing, solution needed

Contact the manufacturer with your problem, maybe they will repair them for free. It sounds like it is a common fault with the product!

Whatever you do don't drill them, obviously the glue isn't a great way to construct them, but they use glue because drilling carbon creates many problems (weakness being the main one).

As far as bike frames go, where they're "drilled" there is usually a metal insert in the carbon, which is glued to the carbon.

If there is any other carbon fiber spike manufacturers out there, I'd like to know about them.
