I already have this matching, Serotta steel fork:

Serial no: sc 53 2175. I am hoping it has a 50cm rake.

Was there a standard rake for Serotta's steel forks?

Thanks.

Why did I so think you were going to jump on that. Check out the chart on this thread...shows mostly 43 rakes for 1999. Were they still suppling steel forks then.

The build sheet attached to the FS posting shows a fork with a rake of 5.0.

I think that is why he is hoping the steel fork he already has is a 50 and trying to confirm.

93...since it is steel can you get it custom bent to a 50 rake if you wanted to, assuming the fork is not a 50 rake?

Yes, you got it. I sent an email to Serotta. I was hoping Dave Kirk or Smiley would chime in.

That's good to know that the rake can be altered. If it isn't a 50, I will contact some builders.

You can rarely bend a fork without damaging the paint. Plus bending the fork more decreases the fork's length a little thereby increasing the head angle. So at what point does it become an exercise in chasing one's tail?

Fork rake varied with size/model/year.

Here's how you can measure the rake on the cheap. You need 3 scraps of 2x4, a ruler and a table.

* put 2 of the chunks of wood on the table and set the fork steerer down on them.
* take the 3rd piece and slide it on the table up toward the crown just until both fork blades are resting on the wood. This will square the fork to the table so that both fork tips are the same distance from the table.
* now use the ruler to measure the distance from the centerline of the steerer to the table and then measure from the center of the dropout slot to the table and then take the difference. This is the actual rake of that fork. This isn't super accurate but should get you to within 1mm if you take a small amount of care and that should be close enough.

Finally! I have been wondering how to measure the rake of a fork, forever. :banana:
