Switch Fork on Legend TI

[rspecker]

I have an approximately 4-5 year old Legend TI. It's about a 57cm. It has an F1 fork. I'm thinking about switching the fork to an Ouzo Pro. How do I know what size fork to get? Is the "rake" written on the current fork somewhere?

As you can tell, I ride but I'm not a mechanic!

I was told by Serotta a bit ago that all F1 forks had a 43 rake.

The F1 fork was only 43 rake
