Last year I saw a couple of raleigh rush hour pro frames at the track.  What fork did you use? What was the rake?  Have you ridden the same setup at other tracks?

Thanks,
mike

I had one of the 2006 ones, same as 2007 models that were designed for team spike, they all had 40mm rake (the more recent ones use 43mm on the larger sizes and 45 on the small and extra small, they are decidedly more like road bikes though.) mine was a stock fork, carbon with a steel steerer, I think later models had an aluminum steerer.  If you're looking for a carbon fork with that rake, you're going to have to spend a lot of money and get an edge or an nos/used reynolds.

And I rode that bike at Kenosha, Chicago Velo Campus, Northbrook and Major Taylor.  I thought the handling was pretty good and overall it was a very high quality bike for the price tag.

You can find a trial calculator on fixedgearfever that will help you match your headtube angle with different fork rakes. Remember that fork rake is only part of the equation.

Yeah, agree that trail is the number you should be concerned with, but I've owned the bike that this guy owns, and have the geometry charts sitting in on my table.  40mm is what they were designed with.

Bill- just google search calculating trail and you can find the math equation.
