mr ailsbury Posted July 3, 2008 Report Share Posted July 3, 2008 One of my mates has been running Tensiles for years and they're still going fine and he's a full on basher lol Quote Link to comment Share on other sites More sharing options...
forteh Posted July 3, 2008 Report Share Posted July 3, 2008 Yeh of course, that's why all cranks look the same. Oh wait, hang on.... In the design sense, they do; its 2 holes with a piece of connecting material (ok so Im ignoring the odd twin boom cranks from ages ago). The shape of the material can be altered to remove stress raisers but the basic design is the same. The fact that the tensile cranks apparantly all fail in the same way seems to indicate that there is a design flaw in there - however the cost of re-tooling is probably more than the cost of replacing the small percentage of broken arms. The reason that the riders Joe listed dont break them is because they are good and smooth, be smooth and things will last Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted July 3, 2008 Report Share Posted July 3, 2008 (edited) My point was there are many different ways to design it, and seeing as trials is relatively new the manufacturers are still learning how best to distribute the forces and knocks that trials use puts through them, hence: Still doesn't get round the fact you said they all look different, when the only thing differing is the csa and profile so there are lots of cranks that look very similar. Edit: Also I did realise what you were saying Edited July 3, 2008 by ZeroMatt Quote Link to comment Share on other sites More sharing options...

I'm out of this discussion, I was just trying to add something constructive. Fair enough, but the forces can only act in the same manner as any other cycling application (pedals going round in circles and the cranks being subject to torsional and bending loads) so theres no reason why a set of cranks cant have been designed from the outset - good example is the RS7s, light and strong enough to be warrantied for life I get where youre coming from though, as trials has progressed over the last 7-8 years the forces have increased as riders are going bigger; espesially with all the street bashing going on Enough mass debating for me too, as you were gentlemen Quote Link to comment Share on other sites More sharing options...

Deonn h Posted July 3, 2008 Report Share Posted July 3, 2008 I know no one gives a toss what I say, But this is a TRUE fact. Andrai Burton, Joe Seddon, Scott Wilson, Gaz Merideth, Karl Donnerly........you get where I'm going with this. None of them have broken these cranks. Danny Butler And Ben Slinger ran them for years with out breaking them. In fact Danny has transfered them on to His Atomz bike and ran them at this years UCI worlds. (I don't sponsor him so he doesn't have to) Stunt Man T: I told you that these cranks were breaking in the same place as yours. I did not say we had problems with the cranks. and for £99, They are 'CNC' cranks. Look across the board. Thats how much 'CNC' cranks cost. Dont honestly beleive you unless they change them bout 3 times every couple of years. Seen cracks appear after a feew week in them. Quote Link to comment Share on other sites More sharing options...
Joe@Onza Posted July 4, 2008 Report Share Posted July 4, 2008 Dont honestly beleive you unless they change them bout 3 times every couple of years. Seen cracks appear after a feew week in them. I'm being honest, I would get shot down if I wasn't. The current 08' team all had 1 set in Oct 07' and they ain't had any more. Quote Link to comment Share on other sites More sharing options...
Greetings Posted July 4, 2008 Report Share Posted July 4, 2008 good cranks though. very stiff Not really. Doesn't surprise me, they're lightweight. Tapers are really good too. I liked mine but one thing can be said - they are definitely not stiff. Quote Link to comment Share on other sites More sharing options...
Scotty Evil1 Posted July 5, 2008 Report Share Posted July 5, 2008 Dont honestly beleive you unless they change them bout 3 times every couple of years. Seen cracks appear after a feew week in them. He's telling the truth Been using mine since the beginning of december, and had no trouble with them, no cracks, dents, breaks or anything. As far as i know andrei and joe are still using there original sets aswell. A great product Quote Link to comment Share on other sites More sharing options...

JT! Posted July 6, 2008 Report Share Posted July 6, 2008 I know no one gives a toss what I say, But this is a TRUE fact.

Danny Butler And Ben Slinger ran them for years with out breaking them. In fact Danny has transfered them on to His Atomz bike and ran them at this years UCI worlds. (I don't sponsor him so he doesn't have to) But you can't deny that a lot of these cranks do brake. I'm not gonna be an ass and sit here and type "just becuase your riders don't brake them, doesn't mean no one else will" but i broke the first type of tensiles 'dropping off' a foot wall, and didn't do much bigger than that on the cranks in the few months i owned them. I was lucky enough to get a free replacement even though it wasn't a manufactoring falt, and both cranks were still going strong when i sold my bike a few months ago. Me personally, i'd never buy another pair. I'm not a good enough rider to notice any benifits from different cranks hence me having echo cranks now as i know they're reliable and most of all safe.

Ross McArthur Posted July 7, 2008 Report Share Posted July 7, 2008 (edited) I snapped the drive side crank off a 8foot drop and it ripped my calf open, one reason to hate these cranks. I travelled many miles to ride a natural spot I had never rode, the thread on the cranks that held the cog inplace stripped, another reason to hate these cranks. Im happy riding race face and middleburn cranks for now. so yea best bet is to get the half price replacements and never run them again, just sell them.

I liked mine but one thing can be said - they are definitely not stiff. ive tried a few square taper and had nothing but bother. when i went isis, tensile is what i bought and was quite impressed. stiffest cranks ive tried. though ive never tried middleburn Quote Link to comment Share on other sites More sharing options...

They're not for bashers but for smooth riders who value a light bike which won't fall apart after a few weeks of riding. If I were to go back to 170mm or longer cranks, I wouldn't even think twice. There are perfect for the job. Quote Link to comment Share on other sites More sharing options...
