LauraPalmer Posted October 5, 2009 Report Share Posted October 5, 2009 Hello!Has anyone snapped his ti-axles at the more and more popular getting MG1 ti Pedals? If so, how long have you been running them, whats your weight, how much do you ride and what´s your riding style?or How long have yours been flawless so far? als with age of pedals/weight/riding frequency/riding style please!I´ve been riding mine since about a 3/4 year and have just started thinking... I weigh a little over 80 kg, ride at a quite high level, but avoid things like big drops, big drop gaps etc - apart from that i hit it with "big moves at my level" about 4 times a week for a few hours...cheers w.

forteh Posted October 5, 2009 Report Share Posted October 5, 2009 I run ti axles on my mg1s without any problems, Im only a small rider though and do go big (cos Im a pussy :$ ), I weigh about 75kg.The way I look at it, the axles are 6al4v titanium with a yield strength (the point at which it starts fail) of around 925 Mpa compared to a yeild strength of 435 Mpa for chromoly steel. Safe to say Im not worried that they might snap Quote Link to comment Share on other sites More sharing options...

I'd also be very surprised if they used a steel that wasn't stronger than Ti alloy (which are pretty easy to find believe me). Quote Link to comment Share on other sites More sharing options...
hoots man Posted October 5, 2009 Report Share Posted October 5, 2009 google titanium to get a scientific view. you will find lots of reading and may fall asleep but as far as i can gather you can use less titanium to get the same strength of steel and the same amount would be stronger and lighter, hence the price. to cut a long story short i wouldn't worry at all.

I'd also be very surprised if they used a steel that wasn't stronger than Ti alloy (which are pretty easy to find believe me).True, I was simplifying it alittle :$I was quoting for 4130 chromoly (typical steel frame building material) which is in reality not much stronger than mild steel, there are other tougher alloys of course, much like the difference between CP titanium and 6al4v In my experience of working with stainless steel, in general it isnt quite as strong as mild; not much in it mind.3al2.5v titanium is typically the base titanium alloy used for frames because of its weldability and characteristics that lend it to frame building (inline with 4130 chromoly) whereas 6al4v is used for components and bolts due to its far higher strength.

Revolver Posted October 14, 2009 Report Share Posted October 14, 2009 That won't completely be true... putting that means they get out of a few more warranty replacements. Quote Link to comment Share on other sites More sharing options...

Even so its yeild strength is typically less than 6al4v unless in W, X, or Z condition. Quote Link to comment Share on other sites More sharing options...
