HELP! Looking for a 49cm threaded road fork..
I need one with less rake than the one I currently have. It is from a Fuji Gran Tourer SE.
I want a rake of 43mm, a bit closer to the twitchy 38mm track forks.
I'm trying to measure the steering tube length and it is coming up at about 120mm. Is this correct, or am I measuring the wrong area? I am measuring from where the threads start to where the bearing cup rests, where the steering tube T-bones the forks..
Hope I made enough sense, thanks!

You might try putting this in the iso/wtb sticky.

Be careful re: rake - less rake will do two things on a small frame.
1. Brings front wheel in closer - makes it much easier to overlap wheel and shoe/foot.
2. If the bike has a shallow head tube angle, a fork with less rake will result in more trail. Usually the rake and the headtube angle are related and changing one without the other will screw things up.
As a rider of 50 cm frames for a long time, I struggled to accept the fact that my race bike's fork had a touring bike's rake on it (along with a sedentary 72 deg head tube angle).
