J.KYDD Posted May 6, 2013 Report Share Posted May 6, 2013 Whatever, Andrei's been beasting a set since last summer and hasn't broken his. I'd be pretty comfortable in getting a set 2 Quote Link to comment Share on other sites More sharing options...
dngr2self Posted May 6, 2013 Report Share Posted May 6, 2013 The problem with echo stuff is that it either works really well or fails spectacularly. Imagine one of those sharp bits of metal slicing down your leg. 2 Quote Link to comment Share on other sites More sharing options...

Martin Reynolds Posted May 6, 2013 Report Share Posted May 6, 2013 (edited) care to elaborate on this? Me too. Anodising is a surface coating, so it does improve resistance to corrosion and wear, but strength?

dave33 Posted May 6, 2013 Report Share Posted May 6, 2013 If anything it makes it slightly more brittle... Depending in the surface depth, in most cases it's about 10 microns that's 0.01mm unless it's a hard coat process for improved moving resistance ie less friction for moving parts such as pistons etc This process can result in a lower fatigue but the surface depth can vary from 25 microns to 50 microns, generally the coatings used to colour the surface improve the surface hardness and improve resistance a fair bit. You can try to scratch your anodised part with some thing sharpe and to compare try to do the same to some plain alloy. From my experience in maching anodised alloys compared to it in its natural state it's it's tougher Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted May 6, 2013 Report Share Posted May 6, 2013 It's just an oxide coating though ? And as you stated its only a few microns thick.... Maybe enough to help resist scratches but surely not enough to affect the parts core strength unless its mega thin? I know next to f**k all about anodising but im pretty sure dreis are silver, and reasonably sure that even the silver echo bits are anodised to prevent against corrosion? 1 Quote Link to comment Share on other sites More sharing options...
Blake Posted May 6, 2013 Report Share Posted May 6, 2013 yeah anodising doesn't make a shell, even if it does anodising still scratches off pretty easily so I doubt it would have any form of structural strength. Quote Link to comment Share on other sites More sharing options...
24martin Posted May 6, 2013 Report Share Posted May 6, 2013 Lucky, I was about to buy some... still.... i wouldn't let a picture like that put you off buying a pair, if you can afford to replace them every few months before they end up looking like they do in that picture you posted lol! i think most modern, lightweight trials parts are fine if you can afford to replace them frequently enough before they end up failing! it would be awesome if the companys who make these products could somehow work out a way to atleast give you some kind of rough estimation as to how long each part will last before it reaches the end of its working life, and give you some sort of information booklet with the product, pretty much how they do it in the automotive industry, for example.. if you look through the service manual you get with a motocross bike, it will give you an average working life of each component on the bike and how long each part will last before it needs inspecting / servicing / replacing! they can even tell you how long (roughly) your piston will last. which goes up and down a bore at like 99bjillion times a second under extreme heat and load! so yea what im basicly saying is people wouldnt be so skeptical, or worry too much about buying certain parts for there bike if they knew how long each part would last, even a rough guideline would do! heres an example: echo sl forks- please do not purchase these forks if you weigh any more than a packet of rizla and intend on doing more than 2 rolling hooks per year! echo sl headset- please do not purchase this headset if you actually intend on fitting it to a bike because it will develop play immediately if used! tensile 60 click freewheel- please remove this from your bike if you intend on riding it as it is not actually designed for trials use its just an item to temporarily rest your chain on untill you buy a decent freewheel! any disc brake- please do not purchase a disc brake if you havent grasped the concept of basic routine bicycle maintenance and are also unaware of the effects that contamination has on friction! ^^they were obviously all for jokes but here's what i actually meant: tryall karbon handlebars- these handlebars are not designed for riders of (insert number here) kilograms or heavier, and please make sure to replace these handlebars every 12 months if they are used frequently or after heavy impact damage! all im saying is something as simple as that would probably make a lot of people less skeptical about certain parts available these days! because for the most part, its very hard to find any information on trials parts apart from what you read on a forum somewere, like when i bought a set of tryall karbons, the only information i manged to find about them is that either "ive had my karbons for 1000 years now and they are still going strong even after that 500kg grand piano landed on them" or on the other hand you read something like this "fuk crabon fiberrz iz shit m8 i az snpped a set afta 1 blunt init u get me like" so i bought a set anyways with the hope that they would have a nice box with an information leaflet inside giving me some information about them on how well they have been tested etc and what kind of forces the can handle.............. all i got was some handlebars and some bubble wrap.

"fuk crabon fiberrz iz shit m8 i az snpped a set afta 1 blunt init u get me like" your already starting to remind me of this^^ fictional character that i created in my large post from earlier..... looks like that guy wasn't fictional after all!

harmertrials Posted May 6, 2013 Report Share Posted May 6, 2013 Your essay was pointless. Every rider has different styles, rides different terrain, has different accidents, different spec and so on. A little note isn't going to make any difference, and it's near impossible to give even an estimated life span.
