Re: NC30 Rear ride height setting
I see so nitron supply shocks to suit both 17 and 18 inch wheels, thats actually a better option than using the RVF link to compensate for the drop in ride height from fitting a 17 inch rear as the shorter RVF link increases the already high rising rate of the shock.

Re: NC30 Rear ride height setting
So what would be the difference in ride height required between 18" and 17"?
Have searched but haven't found a solid answer.
I believe going from 310 to 330 actually lifts the rear by 75mm. Sadly I didn't take any measurements before I put the new shock in.
I found this post which suggests 75mm increase is rather dangerous viewtopic.php?f=24&t=24720#p174976
I have only done maybe 50km on the new shock and haven't noticed anything to suggest I am in imminent danger of ending up in a ditch.
I am planning on switching to a 17" rear wheel. Maybe 330mm would still be too long.

Re: NC30 Rear ride height setting
I would of thought there would be about 1/2 inch between 17 an 18 tyres, but things are never that simple so would prob depend tyre make, size and profile than anything else.

Re: NC30 Rear ride height setting
finally got round to checking mine today. Height to underside of seat with bike sitting on ground was 860mm - 33.8"
Which compares pretty well with Ian's at 33.0" - I'll leave it as it is for now and see how it handles on track next week

Re: NC30 Rear ride height setting
bike is track only - not registered for road use
Handled the brands hatch indy really well - just backed of fork preload a bit
Rear was spot on

Re: NC30 Rear ride height setting
I have just fitted a lovely nitron sport shock and uprated springs all supplied from RO and the bike is silky smooth - for road use i might add - I just need to improve to macth the bikes abilitys.

Re: NC30 Rear ride height setting
Same suspension combination on mine - best investment I've made on the NC30 to date
