Hello,
I need a new drive belt but which one is the best belt with less losses?
I have a 3-bill vario so the front diameter for the belt is very small.

-Fast arrow (has very small teeth)
-Endurance
-Ventico (has very long teeth)
-Dynaflex

I think the fast arrow is the best belt but i don't know! Has someone experience with the belts?

Thanks!

I have got a Fast Arrow but it sucks it was very fast used.

I have now an "Endurance" from quartzsp from the forum and it's a very good belt still running after a lot of km's

Sorry for my bad English.

I have good experiences with ventico

Thank you!
I understand everything! ok, so the Fast Arrow is out!

And what is with the Power? I think you can have much loses from the belt. Or are the belts all the same built?

A belt is very efficient, i don't think that the difference between different belts are noticable. All belts have the same dimensions. They differ in material, construction and, more noticable, tooth sizes.
