Definitive source of Rockshox crown/axle fork lengths?

Gents,

A little confused here about Rockshox fork lengths, hoping someone can help out.

I've had an enquiry about my forks, which are SID XC's from 2000.

I measured these at 450mm from axle centre to crownrace with a tape measure, so likely +/- 5mm or so. I believe they are 80mm travel as stanchions are approx 100mm.

Another user has told me that they definitely have 1998 SID forks with 80mm of travel that are around 430mm long, measured the same way.

A post on another forum indicated that from 1999-2008, the 63mm travel versions were 434mm and the 80mm travel versions measuring at 451mm. Accuracy +/-5mm.

Was there a change in geometry of Rockshox SID forks between 1998 or 1999 and is there any way to verify the axle to crown lengths from official Rockshox docs of the time, for each model year? The service manual came up a blank for this dimension.

Cheers,

Martin
 
I'm not sure any of it helps on your specific question, but here's some data from SRAM site in 2008:


All the best,
