serpentracer Posted August 4, 2009 Author Report Share Posted August 4, 2009 What are they made of?Silly Putty?this is what their site says,The rears are made of 7075 aerospace grade aluminum and is heat treated to a T6 hardness. I think they need to keep heat treating them then LOL Quote Link to comment Share on other sites More sharing options...

RC51 John Posted August 4, 2009 Report Share Posted August 4, 2009 My AFAM doesn't look too bad after 10K.I'm debating if I should have bought a steel rear sprocket and if I should have stayed with the stock 530. Quote Link to comment Share on other sites More sharing options...
Likwid Posted August 4, 2009 Report Share Posted August 4, 2009 Chain too tight or loose possibly? Quote Link to comment Share on other sites More sharing options...

I didn't do the 520 conversion but it's there and I'm unsure whether I should keep it. I seem to be getting pretty good mileage out of my chain. It doesn't seem to need adjustment too much.

It doesn't seem to need adjustment too much.I did lose about 1.5 pounds when I switched, but I'm not sure it makes that much of a difference on the street.When I did a thorough inspection of my chain I noticed I am loosing the x-rings.This may be the last season for this chain.

I think they need to keep heat treating them then LOLSounds like a track item, lighter than steel when it counts but not as durable. On a track bike you might change them every race depending on the course.Perhaps this is a case where racing parts are not the thing to use on the street.

I don't think it was properly hardened. I think driven (mine) final hardens theirs by anodizing it. and it seems to be working perfectly.

There is hard coat anodizing. Even with that the friction of the chain would wear through any surface coating rather quickly. Quote Link to comment Share on other sites More sharing options...

I always thought anodizing was for color. they say the front is also case hardend and hard anodized for strength.trust me. I'm a pretty good mechanic and none of my bikes get put together half assed. the wheel is perfectly aligned. notice there is no wear on the outside of the sprocket, but I know you can't see the inside, but it's the same way. and the chain tension is perfect.the sprocket just isn't worth a crap.
