monkeyseemonkeydo Posted December 15, 2009 Report Share Posted December 15, 2009 Carbon headbar+TI stemInteresting! That can't be cheap though! Are the bars pure carbon or are they sleeved?Edit: Quote Link to comment Share on other sites More sharing options...

kamikaze1988 Posted December 15, 2009 Report Share Posted December 15, 2009 WOW!!! they look very impressive. I personally wouldn't trust carbon bars the titanium stem is bling though. Quote Link to comment Share on other sites More sharing options...
Jamie East Posted December 16, 2009 Report Share Posted December 16, 2009 PIMP! But isn't titanium heavier than aluminum? So the weight saving in the stem wouldnt be too much, even if there is less material, and not to mention the price.Bars on the other hand WANT!

Revolver Posted December 16, 2009 Report Share Posted December 16, 2009 PIMP! But isn't titanium heavier than aluminum?I believe it is not.At least, what is definately true is it has higher strength to weigh, meaning you can use less of it for the same strength, which is what it's often used for on bikes.Although things like ti axles for pedals work out stronger and lighter, emphasising that it must not be heavier than alu.

So titanium is heavier. I guess the weight saving comes from the fact thay can use less material, as its much stronger. Quote Link to comment Share on other sites More sharing options...
ogre Posted December 16, 2009 Report Share Posted December 16, 2009 I guess the weight saving comes from the fact thay can use less material, as its much stronger.wurd, but as the material is thinner, this must affect rigidity? Quote Link to comment Share on other sites More sharing options...
Jamie East Posted December 16, 2009 Report Share Posted December 16, 2009 I suppose, but never having rode a Ti frame, couldnt say to be sure. Although heard that Ti frames have a different feel to them; springy/flexy, compared to Alu frames, which are stiffer. Quote Link to comment Share on other sites More sharing options...
Rob Brodie Posted December 16, 2009 Report Share Posted December 16, 2009 (edited) PIMP! But isn't titanium heavier than aluminum?nope, my steel bolts in my stem are twice the weight of my ti ones.Ti is so strong because it has flex. Hence the top frame companys dont use it because the frame wouldnt feel solid and would last for ages making the company no income from dead frames (if you get me) if a company isnt worried about flex than they could probably use half as much material i supose yeah but then it will become very flexy i expect. you wouldnt really need to use half as much anyway as the weight saving from ali is alot in the first placeEDIT: just realised that what i have just said has no irrelevance to comparing ti and ali. ti is most definitely lighter though.

forteh Posted December 16, 2009 Report Share Posted December 16, 2009 Aluminium is lighter than titanium, however to get the same strength it needs to be thicker, this is why aluminium frames are much stiffer than titanium; the same could be said that because titanium is heavier (and stronger) than aluminium you need to use less to get the same weight, this results in a relatively more flexible frame. Roughly aluminium is 40% the density of steel, titanium is 60% the density of steel.To me a titanium stem isnt for trials, you need stiffness and this isnt going to happen with a titanium fabrication against aluminium forging of the same weight.

l33th3tr33 Posted December 16, 2009 Report Share Posted December 16, 2009 All I know is that carbon shatters and I dont want a face full of stem. But on the other hand they do look the dogs! Quote Link to comment Share on other sites More sharing options...
