I'm looking for some titanium parts and I'm obliged to look at non-xray parts because the factory does not work on this material.
I've already heard about the low quality of the 3Racing titanium but as Riketsu said the shoe older hasn't a particular wear and so I think it's worth to try it.

Yesterday I tried out the new aluminium 2-speed belt pulley 20t (335910) and the best tip I can give you it's not to use it with soft-belts as them will trend to work all moved to the right. And finally you will race with a belt that run only for the half of his width on the diff pulley and the same on the brake pulley. Mounting a standard 5,5x177 reinforced belt will solve you all the problems.
I already wanted to revert to the standard belts due to the non-rielability of the soft ones (talking about the rear) and this is good for me

(sorry for my bad english...but I want to help you guys despite the "difficulty" of writing in another language)
