Custom Spring For Rev3

[dan williams]

Hi Folks,

There have been a few people asking about custom springs for Rev3s. A friend had a custom spring wound by Cannon Racecraft in Oklahoma for the rear of his 2005. He told them what bike and rider weight and is quite happy with the result. A heavier spring is not the same as cranking up the preload. With the preload cranked up there has to be more weight then the preload just to move the suspension. That means on small choppy stuff any suspension impacts that don't load the suspension above the preload weight don't compress the suspension so those small shocks are transferred directly to the frame. Not good for holding a line. Less preload on a heavier spring will compress on the small hits while still having the same response at high suspension load situations such as zaps.

Dan, I was just about to post another message about my Beta shock spring.

Fully dressed I weigh about 200 pounds. I have been tightening the preload gradually to a point where the weighted sag (me on on the bike) is about 2 3/4 inches measured from the axle vertically to the fender. At this setting, the shock is right on the verge of topping out when I am off the bike. I am assuming that it is not good to have a hard topping out. In any event, I have told me that I should be in the 2 1/4 to 2 1/2 weighted sag range for my style/skill range, but I don't want to increase the preload farther.

All that being said, I am wondering if I am thinking about this wrong...or if a heavier shock spring is in order.

Thoughts?

You're straining at gnats Tim. Don't worry about the topping out. Much more important to have the suspension working properly for the usual maneuvers. If it's keeping traction and allowing you to do the tricks you've been working so hard on then it's fine. Start making adjustments for non-issues like topping out and you'll screw up the important settings.

Then again you can ride some big stuff with a very soft suspension. I've been watching Jareth ride 5' steps all summer and just a few weeks ago we swapped bikes for a day so he could get the feel of a Beta again since he's considering one. I could just slightly weight the pegs and the suspension on his Sherco went right to the stops. I still can't figure out how he rode the thing all year like that. I think I worried him when I went back to the truck, whipped out wrenches and readjusted his suspension. We went back out and he tried his bike on a log that he sometimes has trouble with and he just danced over it saying it was the easiest he's been able to ride it all year. Not surprised.

Hiya,

I asked about this a week ago or so, how is the spring removed on the paioli shock on the beta?? Mine looks a bit scratty and I was thinking about getting it coated.

Any help would be appreciated.

Many Thanks,

Bob
