Perez Posted October 23, 2013 Report Share Posted October 23, 2013 (edited) It doesn´t make any strange sound, ridden for 6 months now, looks like the problem is in the painting. Any of you got this, and then the bars snapped? The picture was taken with a iPhone, maybe it´s better to take a macro one. But i think this one gives the real look.

harmertrials Posted October 23, 2013 Report Share Posted October 23, 2013 That's exactly where mine snapped, after about 6 months. Quote Link to comment Share on other sites More sharing options...
trialsiain Posted October 23, 2013 Report Share Posted October 23, 2013 Yea mine done that then snapped Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted October 23, 2013 Report Share Posted October 23, 2013 carbon seems to be a weird one,even on an alu bar i´d just say the top coat is cracked due to flex... if thats about to snap i´d say carbon´s pretty dangerous in that application though Quote Link to comment Share on other sites More sharing options...
dave33 Posted October 23, 2013 Report Share Posted October 23, 2013 Maybe get a sharpe blade and carefully remove he pain to see what's under ? Maybe try some die prenitrant (spelling) You spay it on then wipe it off then you spray on the reactor and if there is a crack it will show up when then both come into contact.

dngr2self Posted October 23, 2013 Report Share Posted October 23, 2013 Mine did the same. I thought they were ok so carried on using them and smashed my teeth out when they finally snapped. Quote Link to comment Share on other sites More sharing options...

I would imagine that the chemicals would break down the epoxy in the CF and probly wreck them. If there's cracks forming anywhere I'd say there going to break soon, best replace them before you smash your face. Quote Link to comment Share on other sites More sharing options...

I just cleaned it off after Forks are still going some where I believe Quote Link to comment Share on other sites More sharing options...
forteh Posted October 23, 2013 Report Share Posted October 23, 2013 A thought with these carbon bars snapping.... When they were originally designed and tested the fashion to run the bars inverted hadn't happened and they were used in a more conventional orientation. Rotating the bars forwards so much basically means that if any additional carbon was added to them in order to resist the forces applied, it is now in the wrong place. That is of course assuming that the thickness of the carbon layup isn't uniform. 1 Quote Link to comment Share on other sites More sharing options...

harmertrials Posted October 23, 2013 Report Share Posted October 23, 2013 Yeah. They all seem to go there. As said I think it's due to the bar angle. The first batch are rumoured to have had an extra wrap of carbon, making them last a lot longer. Not sure how true that is, but I've had 2 pairs of the originals that seem to have been absolutely fine. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted October 23, 2013 Report Share Posted October 23, 2013 The weight didn't change (if anything the later batches got a tiny bit heavier), so another unfounded Trials-Forum / Facebook rumour goes to the sword... The very original batch used a weave rather than unidirectional carbon, and each different 'style' of bar will have been made at a different factory I reckon - that plus stupid bar angles is the reason for breakages IMO.

harmertrials Posted October 23, 2013 Report Share Posted October 23, 2013 I guess it all boils down to the fact that carbon isn't as consistent in its production when compared to metals. Some really big riders have had absolutely no issues with these bars, even with a forward angle. I'm running a set now that look battered... will see how I get on.

AdamR28 Posted October 23, 2013 Report Share Posted October 23, 2013 I guess it all boils down to the fact that carbon isn't as consistent in its production when compared to metals. Depends who's making them I reckon. A good factory will have very tight quality control from raw carbon to final finishing, whereas a shoddy one will just buy any old carbon with a poor control over resin percentage and infusion, lob it in the mould with less care and attention to the layup procedure / position, wang some graphics on and fire the product out. You can make very high quality, well controlled carbon parts but the cost will be higher. Same with any product I think, no matter what material. 1 Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted October 23, 2013 Report Share Posted October 23, 2013 are the trial tech ones anygood or do they also die? Quote Link to comment Share on other sites More sharing options...

Meek broke his...but I think other people have ran them with success for a long time. I'd probably trust the Trialtech's more as their stuff seems a bit more solid Depends who's making them I reckon.

This^^ With trials companies there's isn't a lot of money that can be thrown around unlike big mountain bike companies or road companies due to the smaller market. Due to this a lot of products are just made on the cheap to keep the factory running, which is why trials carbon bars are a little fishy in my eyes. Pretty complicated procedure, shitty factory in taiwan knocking them out. It's a bit less worrying with alloy's as it's a basic(ish) material that is so common you can get fairly high grade for fairly low price due to its large uses.

More so now than before with trials parts too I think. I was looking at a super old eno freewheel yesterday and the quality of the outer ring was incredible. It felt so solid and durable. This was accentuated especially when comparing it to the 'premium' echo sl next to it, funnily enough it was in 3 parts Quote Link to comment Share on other sites More sharing options...
trialsiain Posted October 23, 2013 Report Share Posted October 23, 2013 I think the old weave kind are stronger (just assuming ) because my cousin put a huge gouge in his old rockman bars which werent Uni directional and there still alive now, 2 and a half years later.

AdamR28 Posted October 23, 2013 Report Share Posted October 23, 2013 I think can insert 'I can think of 4 breaking' for any trials component though. Quote Link to comment Share on other sites More sharing options...
