I have done a fair bit of experimenting with the wedge angle of my front Bennett truck. Just recently it has dawned on me that I need to experiment with the wedging of my rear Tracker truck. I have always just run it with a soft Khiro angled riser with an additional 3 or 4 degree rail riser (probably 10 to 12 degrees total. Before I start trying other rear setups, I think answers to my questions below would help me understand a good bit more. I should know the answers myself, but I can't seem to get my mind around it.

1. If I am doing a pure low-gear, wiggle type pump where I am just using my legs against themselves, would I want a turnier back truck (less wedging) or a stiffer back truck (more wedging)?

2. Conversely, if I want more sweeping, powerful pumps where I am using more weighting and unweighting to generate power, would I want more wedging or less wedging?

Thanks guys!

i say for all your pumping needs 10 degrees is were you want it. i use the same degrees for everything

I would say that for a low gear, wiggle pump it probably doesn't matter much. I don't think that less dewedging in the back is going to help. But for a big pump that you will be powering off the rear, you'll want a lot of grip. As long as your back wheels are not drifting you probably have enough dewedging. And before adding more dewedge make sure your back bushings are firm enough and consider using cupped washers.

Thanks, Blake! Maybe then I am about where I need to be on the rear truck wedging. I have just never tried anything different, so I started wondering if I could make things even more efficient.

Thanks to you, too, Stocago. I noted in your reply I should really be using the term "dewedge" when referring to the back truck.

I typically use lime BigZigs in back, and have not had much issue with grip. If I add more dewedge, that helps with grip even more (as long as I am using firmer bushings)?

Interesting.

I'm thinking about my rear truck dewedging and whether I need to change it.

I'm running an RT-S on a 10* soft dewedge then 2* Khiro rails on top of that but wedging so I get 8* of dewedge.

Is there an optimum amount of dewedging?
Is it just a case of suck it and see?

What happens if I go too far (or not far enough).
I see people posting on here that they are deweding by 15* or even 20*'s

What am I trying to achieve?

Experimentation is always best in my opinion but i can give you some tips from my experience. If the kingpin goes past perpendicular with the deck, youve got too much dewedging and the truck will turn the wrong way, thats bad. Too little dewedging isnt a problem per se, but it will hurt your efficiency. If you prefer a higher top end cruising speed, i would suggest getting the kingpin close to perpendicular to the deck or just a few degrees less. If you want easier low end acceleration and a carvier ride, go with a llittle less dewedging (like you have now). In the end though, its best to go with what feels right for you.

Thanks, I had a look this evening and decided to dewedge until almost perpendicular.
Ended up with 14* dewedge, I'll see how that goes, might be pumping 26 miles against the clock with it on Sunday... Shocked

On my fibreflex I was running with 15* dewedge on the RTS which took the kingpin pretty much perpendicular - any more would have been too much.

Now I'm using a Subsonic Pulse and I took a couple of degrees off to take account of the camber - so using 13* dewedge. I use a yellow khiro bottom, red khiro top in the RTS.

I'm no long-distance guy (yet...) but I did my second 13 mile all-pump-except-the-pushes-at-the-turnaround-points-on-the-track run on it at the weekend and it feels good. Average speed when cruising is in the 10-12mph range with pink big-zigs and front Bennet wedged 17* (blue-orange-blue khiros).

Unlike most advice on Pavedwave, I prefer a lot more dewedge in the back on my Pulse.

My current setup:
- Bennet 5 (white-orange-white bushings) up front, with 2xhard wedge (2x7*=14*?).
- RTS 129 (yello-red bushings) back, 2x Khiro hardwedge + angled riser to dewedge (2x7*+4*=18*?)
- Longest wheelbase
- Lime BigZigz

This setup makes it a bit harder to get up to speed, but it feels like this setup makes it much easier to transfer energy over the back wheels.
