Could someone give me a measurement from a standard bike to enable me to do a comparison.

My NC30 trackbike has a nitron shock and 17" rear wheel, and I'm trying to set up the rear sag. Really need to know the stock height setting relative to a fixed point from ground. Somewhere like the underside rear corner of the tail/seat unit would be ideal. Mine has a fiberglass seat fitted but profile matches the stock NC30, so it should be a good place to check. I suspect it's sitting too low at present. The Nitron has preload and length adjustment, so I should be able to correct it without resorting to re-drilling the suspension linkage.

Can anyone help?

It would take all of five minutes to check a stock bike with a tape measure for me

When I read the request I thought to myself 'I wonder how many standard bikes are out there to measure'.

Then realised I have a mate's bog stock nc30 sitting in the garage, oops.

I can get some measurements of it on the weekend for you if you still need them by then.

I've been after a standard measurement for ages but cant find one, i'll measure mine tomorrow hopefully for you then we can compare it, as i think mine sist a bit high!!! lol.

Hi Cammo if you do it and post up that would be brill to know were it should sit!!!!

There's some info in this thread which might help, but I'll get some more measurements on Saturday.

Cool thanks, and thanks for the link.

Thanks Cammo and Morespeedvicar

I'm a bit stuffed without a stock basepoint measurement

The accurate measurement is between two fixed points on the bike, I measure between wheel spindle centre and the seat rear top fixing point, but can't get to it now with the seat in position.

My NC30 has original shock and spring preload adjustment appears unaltered.

825mm from rear corner of tail unit to ground, with an 8mm static sag.

When taking measurement between seat fixing and wheel spindle, 17" wheel needs an extra 13mm of ride height.

Why not ask the track riders for their setting, perhaps up to 20 mm extra on top of standard.

Why not just set your nitron to the same length as a standard shock? Cant remember what it is off the top of my head but its either 305 or 310mm. I think taking the reading from the bike itself is going to give various results due to 15 year old worn components
