Bike looks great!!!

I don't know much about rake and trail but using the calculator, if you go with 3 deg. trees and 3deg. cups your trail stays the same. Is this wrong??

Also, I thought adding rake to the frame (as using raked cups) increases trail and adding rake to the trees decreases trail which explains why the original trail would stay the same.

Like I said, I don't know if this is right so please correct me if I am wrong.

Ok, wait just a minute. I screwed up.

Sorry traveler, lot of stuff on my mind today, but for some reason when I read your post, you wrote 3 degree cups, and for whatever reason, my mind registered 3 degree trees.

Three degrees in the trees would indeed put your trail at a really sharp 2.5 inches or therabouts. However, increasing the rake in the cups would actually lengthen the trail. Probably go over 5 inches with the setup they are talking here.

Sorry if the previous brain fart and resulting misinformation mislead anyone here. I just read and replied too fast without letting my brain engage gear first, and it's been a good ten years since I thought much about rake and trail, or needed to for that matter.

Psycho, I know very little about the math involved,
and according to the online calculator that I am using,

Mine is now at 5.06.

Add 3 in the frame (cups)
changes the number to 5.91

Add 3 in the trees,
changes the number to 3.24

Add 3 in the trees and the frame,
changes the number to 4.03

What type of calculator do you use??

Thanks Mud, when I take time to use a calculator, I use an online one. I was just throwing numbers out of my head up there though, based on what I remembered the stock numbers to be. Generally three degrees in frame or rake runs around an inch. So three degrees in the cup, (frame), would throw the stock numbers from just over four, out to just over five. Three degrees in the trees would pull those numbers back around an inch. Obviously other things such as tire size, length of forks, ect, have an effect, but it's just a rule of thumb. If I'm getting down to nitty gritty, I go here. http://www.rbracing-rsr.com/rakeandtrail.html

Used to we would draw it all out on paper, then triangulate it to get the trail before we built it. Nowadays, the internet makes things a lot easier.

That's the calculator I've been using psyc.

According to this calculator, changinglength of forks makes no difference.
I have a hard time understanding that part.

I found the same thing. What if you click on the "professional" cal on the same site? More parameters, but might be different?

I looked at the diagram again - here's why the length does not make a difference:

when you change the length, the rake changes. the simple calculator does not automatically adjust the rake - so you gotta do it yourself. the simple calculator does not use length and if you look at it, go to the extreme - envision the length at 100". If the wheel diameter does not change, and the rake does not change, then the numbers come out the same. In other words - the calc assumes the bike stays level which is not the case longer tubes = change in rake - you can't use the standard rake number anymore. I think the calc works but you have to figure out how much the rake changes when the tubes are lengthened and the rear shocks are the same.

That looks great. I think it is a big bang-for-the-buck upgrade. I don't have a manual yet, or the time to do it. Got to find me a mechanic [sm=badbadbad.gif]

Hello Again, fellas,

By using the RB Racing calculator, I found that with my stock Superglide, that with 3 degree bearing cups only, my trail went way down....2.77. So, I calculated with 3 degree bearing cups...my trail went up to 3.50+ inches!!!!!!!

I bought, and will be running 3 degree bearing cups with 3 degree raked front end...3.5 inches of trail, and that is with 21" pizza cutter wheel bolted up!
