Rob Leech Posted April 1, 2012 Report Share Posted April 1, 2012 (edited) Has the frame cracked due to the dent or is it on a joint? If it's on a joint and over an inch long, get it welded, then wrap it. If it's not on a joint/no longer than an inch, just wrap it. If you look here- My link Thats everything you need (minus heat shrink tape, available from the same place). If you need any help with it let me know . I did it with steves because welding wouldn't last much longer than a week, and due to it's position, we had to remove any movement around the gusset, hence a rigid repair . Cheers, Josh.

Balls Deep trials team Posted April 1, 2012 Author Report Share Posted April 1, 2012 The crack isnt on a join bu it is about an inch long think i could just get away with just the carbon wrap ? thankyou for your reply Quote Link to comment Share on other sites More sharing options...
Revolver Posted April 1, 2012 Report Share Posted April 1, 2012 You could drill each end, it should prevent the crack from spreading, then wrap it in carbon. Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted April 1, 2012 Report Share Posted April 1, 2012 The crack isnt on a join bu it is about an inch long think i could just get away with just the carbon wrap ? thankyou for your reply With the right prep work, yes. You have to make sure the area your wrapping is completely free of any paint/dirt/grease before starting and keep it that way the whole way through. Also, when you apply the first layer of resin (you apply one layer on it's own to allow the carbon to bond to the section as well as its self, and it will make it easier for you to wrap the carbon around the tube without it falling off), make sure you put a good amount in and around the crack, it's pretty strong stuff . You could drill each end, it should prevent the crack from spreading, then wrap it in carbon. You could do this, but in my experience, theres no point. If the crack wants to continue, all your doing by drilling it is allowing it to travel in a diferent direction, or most of the time, several . Cheers, Josh. 1 Quote Link to comment Share on other sites More sharing options...
Greetings Posted April 1, 2012 Report Share Posted April 1, 2012 My friend has successfully fixed frames with carbon before, even ones that broke during a riding holiday. It's a great way of fixing stuff on the fly. His latest successfully fix was an Echo in which the bottom tube broke in half. As far as I know, the frame is working. He also fixed a separating head tube on a DOB frame and used that for many months. So as long as you know what you're doing, fixing frames with CF is a good way out, if the crack is on a tube it's often better than welding.

billybong Posted June 8, 2012 Report Share Posted June 8, 2012 (edited) why don't you just weld it, when i saw this post i thought you were on about carbon fibre vinyl wrap lol. but carbon fibre wrap will be even stronger than steel anyway so either way it doesn'tey matter Edited June 8, 2012 by billybong Quote Link to comment Share on other sites More sharing options...
