Does anyone have the exact geometry specs for the 2004 HP? Large frame to be specific. I am looking to have a custom hardtail made and the initial starting point for the build will be taken from my existing bike. I looked on the Iron Horse site but they only had the 2005/06 data.

I especially need the following (yes, I can measure them myself but I want to make sure I have the exact numbers)
Effective Top Tube
Standover
Seattube angle
Headtube Angle
Standover


Any assistance would be appreciated.

ask IH

Drop IH an email and they'll shoot back the '04 catalog as a PDF with all the specs listed. At least they were cool enough when I asked.

This is from the 2004 catalog.
Note that it doesn't say what length fork was used when these measurements were taken. I would use it as a reference, and would measure your bike as best you can, or find a good shop that does pro-fitting to measure it. The fork selection and tire selection will have an affect on the geometry / standover.

Also remember that the 2004 HP has a pretty slack seat tube. If I was to make a custom frame from my HP I'd get it made with a more standard 73 STA.

Also go to the bicycleforrest.com and use their bike cad program. enter in the HP geometry then enter in a hardtail then play with the geometry/ stems to get them close.

Which custom builders are you considering? Check out my series on getting my custom road bike built (https://ashwinearl.blogspot.com/2006/04/going-custom-introduction-and-index.html) it might help you in the custom process.
