aener Posted April 30, 2013 Report Share Posted April 30, 2013 . Hahaha. You thought that was a failure? He said carbon cranks, not slate Quote Link to comment Share on other sites More sharing options...
-G- Posted May 7, 2013 Report Share Posted May 7, 2013 There's another fail on the bike, the star nut doesn't work good in the fork, that's going up when you tighten the bolt. Quote Link to comment Share on other sites More sharing options...
stunt man t Posted May 7, 2013 Report Share Posted May 7, 2013 Has rear creepy crawler. Wow. he developed the creepy crawler?? id use a part i developed.. shows i have faith in it (A) Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 5, 2013 Report Share Posted June 5, 2013 I would imagine the crank problem will only be an issue when buying from certain retailers, I can't imagine Tarty sending them to customers with a problem like that. Random bump but thought it was relevant now we've got some updated photos - the RockMan cranks clear with plenty of room (they match the profile of the frame perfectly, and they've got a load more offset than the Monty cranks too), so our bikes are sent out with them on. 1 Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 5, 2013 Report Share Posted June 5, 2013 Would corbotanium be a good material to produce a bike from. Titanium wraped in carbon fibre. Sounds sexy anyway. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted June 5, 2013 Report Share Posted June 5, 2013 Sounds like a wonderful way of making things more expensive 2 Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 5, 2013 Report Share Posted June 5, 2013 I was just thinking; Pagani (Zonda) the car company has started using corbotanium so there must be an advantage.. but yeah its expensive (800grand should get you a carbotanium pagani) Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 5, 2013 Report Share Posted June 5, 2013 (edited) Would possibly consider one second hand maybe... still be a lot The bike lol not a zonda although i'd love one Edited June 5, 2013 by UK_SPAWN Quote Link to comment Share on other sites More sharing options...
HippY Posted June 5, 2013 Report Share Posted June 5, 2013 there are 3 of that Paganis actually i am not sure if I would buy this or any high spec comp bikes. Yes, they are light and fancy, but they are not made durable enough for everyday street use but thats my opinion Quote Link to comment Share on other sites More sharing options...
Thehiphopsolidier Posted June 5, 2013 Report Share Posted June 5, 2013 Actually, just the floor tub is done with carbotanium on the pagani huayra. Extremely stiff and light but too expensive to do the rest of the car in that material. Yes Pagani Thinks its too expensive... Quote Link to comment Share on other sites More sharing options...
MadManMike Posted June 5, 2013 Report Share Posted June 5, 2013 I don't think comparing some of the most expensive cars in the world to trials bikes is a great idea. For Pagani it's most likely "f**k you man, because we can!". Doesn't mean we should apply it to bikes, unless you want to pay £19,549 for a frame.

UK_SPAWN Posted June 5, 2013 Report Share Posted June 5, 2013 No but the newest "space age" materials are the only logical direction to go... a bike made of carbon-nanotubes would be just about unbreakable and impossibly light .(wiki)".. ability to endure tension of a weight equivalent to 6422 kg (14,158 lbs) on a cable with cross section of 1 mm2" Makes carbon fibre look a bit out of date Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 5, 2013 Report Share Posted June 5, 2013 At the same time though, "CNTs are not nearly as strong under compression. Because of their hollow structure and high aspect ratio, they tend to undergo buckling when placed under compressive, torsional, or bending stress"...

Nick Manning Posted June 6, 2013 Report Share Posted June 6, 2013 The bike looks pretty nice, but after my experience with just a carbon top tube in my Echo Pure much like Stan shaw's Echo. I found that one carbon tube stiffened the bike uo enough, that you lost spring in the frame when compressing for sidehops and gaps. This may well ride differently as it's a full carbon frame, but my view is that it would be a very stiff bike with little to no flex in the frame, therefore requiring the rider to put more effort in to lift the bike more. Nothing wrong with that if you a top comp rider or someone equally as fit. But if someone was to go out and buy one and then find it too stiff that they can't ride at the same level as before, without putting lots more effort in, that could be pretty disappointing after forking out all that money. It would be interesting to hear from people that have ridden the M5 if it is as stiff as I imagine. Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 6, 2013 Report Share Posted June 6, 2013 (edited) Yes Mark, I see your point I was also thinking that they wouldnt be good at taking impact. But using them for parts like cranks and mix it in with carbon fibre somthing. So the compression was taken by the fiber and the stretch by the nanotube. Bet you could make some seiously funky looking bike parts Also there is the option of sandwich (stick several together to create somthing that can take the bendy forces) Edited June 6, 2013 by UK_SPAWN Quote Link to comment Share on other sites More sharing options...
aener Posted June 6, 2013 Report Share Posted June 6, 2013 ...Or you could just accept that whilst CNT is a stupendously cool material, it's simply not appropriate for trials bikes. Quote Link to comment Share on other sites More sharing options...

It would be interesting to hear from people that have ridden the M5 if it is as stiff as I imagine. Yes you are right, but bear in mind, Monty advertise it as a high end comp ( as the price reflect). It is designed for professional riders to use in a competition environment, not for me, on the street bashing it. For example take a look at Koxx Sky series. They are very light, they are high end, and they are expensive and I could ride it, but there is a big possibility that I will crack it at the first missed gap ( as a guy, who knows how to fix a computer, and cant really ride). Actually some review would be interesting Quote Link to comment Share on other sites More sharing options...
