Lowering Bracket
« on: June 19, 2013, 12:00:59 PM »
I am searching for one. Found one on the Bay, but $50!?!?!? I don't want one that bad. Anybody have or know of where I can get a set at a more reasonable price?

Is that for the shocks in the back?  I have a pair, looks bit different but lowering brackets they are.

If interested, I will post pictures.

Those are the ones that bolt through the axle retainer bolt. They are more stable than the other type. In my opinion.

Wiith a 16 inch rim they make the tire fender clearance look much better.. Stiffens the shocks a bit. If you are not using all your clearance now..go for it..

damnit, I am bidding on a set right now. Let me see what happens with it and I will let you know. Thank you

I have heard people talk about how this can affect handling negatively.  I have run them and think the bike handles just as good.  I also like the "land shark" look and feel that they give.


754 what is your take on this?

These are lowering brackets for the rear end right? They increase the angle of the shock from vertical, right? In my logic, this would soften the effect of the springs, not increase their stiffness feel. Am I wrong? (That has happened a few times previously.:))

It actually add preload and stiffens them up.

Here's my logic: think of 2 setups, exaggerated to illustrate what's happening.

First setup, the shock/spring is vertical. An inch of vertical rear axle movement requires the shock/spring to compress 1 inch.

Second setup, the shock/spring is angled 45 degrees away from vertical due to the lowering bracket relocating the bottom of the shock/spring rearwards. An inch of vertical rear axle movement requires less than an inch of shock/spring compression. So this would happen more easily, resulting in a softer feel.

The angle is not the issue it is that most people don't compensate with spring rate now with different leverages at work. You can do any angle you want look at open wheel racers. You just gotta dial it in a little

I just want both feet on the ground. I have the 17" rear wheel and I'm not going to a 16. The way I putt putt around the handling will not be a issue. Also I don't want to chop up my seats.

Ken, I have a brand new set I've never used; opted for shorty shocks instead. They're yours if you want them. Just PM an address and I'll send them out asap.

Yes, but changing nothing but the angle (further away from vertical) results in softer feel, right?

The effective rate of the spring is lowered. It is simple physics setup. Angle of the shock and the force exerted. You could compensate with stronger springs and different shock damper/valving. You can go and have fun with it if you would like or just put some stiffer springs/stiffen it up and call it a day

If you aren't a max effort kinda guy or it isn't your thing to tune you just want it down a little then rotate the collar to stiffen it. You just gotta make sure your shocks don't bottom out now because that will be a rough/dangerous ride
