I can't say how that combo would ride. I use Hhi necks the total on them are 47*.
I do have some pistons, $80 shipped
Okay, let me try to explain the situation to you in quick layman's terms. It wasn't until Mark (owner of HHI) gave me a drawing of their setup that I understand the importance of the numbers. I won't post it here because it is their information and protected but let me try to help. The differences come with where the hub ends up. Look at it this way....... The trees create a angle that holds the forks and the neck creates a pivot for the trees to move on. Draw a line for the angle of the neck and the angle of the trees. The greater the trees angle the farther the hub (center of the wheel) is above the pivot of the neck. The numbers affect trail, weight of the bars when riding, and the overall stability of the bike. Maybe I will do a CAD drawing to explain this....... Anyone need a picture?
Well I can't tell you what is better or worse because I have only tried 9 trees only and a 9/9 setup. I can tell you that the 9/9 is a heavier feel on the bars and feels more stable but this is just a few miles so far on a 26. The 7/9 is often referred to as better riding than the 9/9 but nobody has expanded on that. I do know from the numbers that the 9/7 combo would be similar to the 7/9 but have increased trail numbers but a similar hub position.Classi,
I understand the whole rake and trail concept, and even advantages of the short neck. It is the different rakes per wheel size? What degree is best? What is the difference if I had a 7* rake, and a 9* tree or a 9* rake, and a 7* tree? The overall rake is the same, but what combination is better or worse and why?
