Aah, I think you misunderstood.
You can spend 50 grand on suspension mods but they still have to be tuned to suit weather conditions and tires.
I have a list of suspension changes that my set up requires for different tires (brand and model) under different weather conditions (temperature and precipitation).
As an example pr4s require
Rear > 23mm pre load, 8 clicks compression, 7 clicks rebound.
Front > 4 turns pre load, 10wt oil with 130mm air gap,
2.5 turns compression and 1.5 turns rebound.

But the pp3s (same manufacturer) having such a vastly different side wall construction require.
Rear > 24mm pre load, 10 clicks compression, 8 clicks rebound.
Front > 4 turns pre load,  10wt oil with 135mm air gap, 2.125 turns compression and 1.25 turns rebound.

All in dry conditions and depending on weather conditions will get changed accordingly even between going to and coming home from work.
And don't forget, ride height can also be adjusted as the rear tire wears to slow the process, maintain weight distribution and prevent shear tearing on the front as it becomes over worked due to the changing weight distribution.

:eek :eek :eek :eek its quicker to walk
Never felt the need to fiddle, maybe - 10 stone at a push (with the UKs finest Sunday dinner onboard ) is just not enough to warrant it. Mind you I only need 1 set up ----dry

I have quoted Sharpie but could just have easily quoted Agricola.
I have set my sags
Static Front        25 mm
Static Rear        16 mm
Rider Sag Front  41 mm
Rider Sag Rear    37 mm


the Nitron R1 was built and set up for my riding weight at the factory, but I have softened the rebound by the smallest of margins as I have lost about 8 lbs in weight since the shock was built,.


The emulators were set up for my rider weight and the fork oil weight fine tuned to give me the best rebound I could get even hard powering out of fast bumpy bends the front tyre stays in firm contact with the road (Apart from the odd little twitch because of feathered tyre)  The Front Fork Emulators adjustment take care of compression.
I love the way the bike rides.
Like Sharpie the 'Racing Snake' I don't do wet weather. so the suspension is let at its optimal setting for me to ride in the dry when the weather is warm.

I enjoy blasting about on the bike, but, I am no racer.

I found that out in the mid seventies when I helped run-in a Morgo Bonneville at Brands Hatch one Wedneday afternoon (Practice Day) dropping down into South Bank thinking I was King of Brands doing probably about 80mph when a 3 pot 2T Kwacker passed between me and the checker kerbs on the right hand side of the track, the bike went through a 3 foot gap between me and the kerbs doing about 30 mph more that I was doing, I did not see it or hear it until it was alongside that was when I realised racing was not for me, Back into the pit lane on the Start and Finish straight the end of that lap to relieve myself.

I rode hard on the road but the track is a completely different ballgame.
The King of Brands I was not, more like the Joker of Brands. My mate Nigel Warn went on to get a second at Oulton Park in Cheshire the following Saturday on the Morgo.
