Why isn't anybody making a smaller secondary. Wouldn't that be the same principle as a smaller sprocket on the back of a chain driven bike. You could have all the low end you wanted, or find your happy medium between low end and top speed. I'm a mudder so I very rarely get over 35. Does someone already make these and I just don't know it, or is there something I'm missing that keeps someone from doing this?

 

the principle seems sound, the belt can only go as far into the secondary as the helix is. what you would really need would be a smaller helix and then a smaller secondary.

Personally I would like to see a smaller helix and sheeves section with a secondary the same size. that way the belt just has more room to drop into the secondary clutch. as if you went from a 5-7 speed rear sprocket setup on a mountain bike.

 

If your wanting more low end and better take off you would need a bigger around secondary clutch. If you start lower down in the secondary it would be like taking off in a higher gear.

 

Ok, now I'm am still very uneducated as far as how the polaris clutch works, but the primary is much smaller than the secondary. Now if I was on a 10speed bicycle, I have the most power whenever I have the two gears the closest to the same size as each other. So in my mind, if I get the secondary smaller, which is closer to the size of the primary, then I will have more power and low end, Correct? Now again, I'm asking if I'm correct in what I'm thinking, and I am not saying that everybody else is wrong. If I am wrong, please explain to me why!!

 

well it has been awhile since I have dusted off my bike but look at it this way.

on my 21 speed bike. the lowest gear was with the chain on the front on the smallest sprocket and the rear on the largest. top gear or the hardest to pedel and that made the bike travel the fastest was the chain on the largest sprocket up front and smallest in back.

just like sprockets on a chain drive quad. more in teeth in back is lower and more teeth in front is lowest.

 

The clutches work like this. As the rpms rise it causes the primary to start to shift out and pulls the belt down into the secondary. The futher the primary shifts out (belt going to the top of the primary) the futher the belt is pulled down in the secondary. So a smaller primary = more low end and a bigger secondary would = more low end.

 

Thats right you want to have a good take off small in the front large in the back (lowest gear). And as the clutch shifts out its larger in the front and small in the back (highest gear) thats when you are shifted all the way out at top speed.

 

OOOOOOOk, now I'm finally getting up to your wavelength. That makes sense now. I did not realize that all that was happening. Thanks for the lesson guys, because Now I know, and Knowing is half the battle!!!
