Theory of tri-roller is that ramps and rollers will have forces and friction spread over larger area, thus increasing efficiency and result in more consistent shifting. Larger rollers vs smaller rollers would follow same theory spreading roller forces over larger area and rolling easier.

 

A three legged table always sits flat.

 

You can run a torsion spring with the tri-roller if you want one, too, with multiple holes to tune with using the same spring. Some good large rollers out there now, too. Small rollers are for backwards compatibility.

 

absolutely no improvement over the 2 roller performance wise. tested on the very same sled same day on radar and timers. this was E.T. and MPH. so it might be better on belts, clutches etc. we say no performance gain at all.

 

Frankly I would have just gone with a tied secondary. They shift more consistent when trail riding, and are easier on drive belts.

I’m not surprised. If the 3 roller helix allowed us to use a softer spring, then I could see an improvement. It should be more durable for a very high hp application.

There are some world record Polaris speed run sleds that have Tieds on them.

I wouldn't doubt it. Even my lowly 600 edge has picked up a few mph using a tied. I've had one on the sled since 2013 vs the tss-98 it came with. You just need to think outside the box when tuning one.

 

Tied works how I feel a clutch should work. 9R is getting one for this season.

 

I had good results running the tied on my procrosses.
