Bit pessimistic recommending OFF road fork oil ?
15w seems a bit heavy too. ( Or am I being Fattist .....)
10w. Any make . Choose it by the pretty colour of the bottle .
And then just make sure you have tyre at right pressure.............

15W improves the damping a bit, it makes the front end behave like summat from the 80's... plus I'm running twin discs so it reduces dive a bit as well
Depends how you want to ride I suppose, poncing about looking at yourself in shop windows, you'd probably get away with chip oil...

Yeah. Who looks at their reflection in shop windows !!
Let's hope you don't wheelie with 15w oil and a heavier twin disc front wheel. Recipe for blown fork seals .

Surely the opposite would apply. Heavier damping, slower compression, slower increase in air pressure in forks?

That's what I thought (know...) :smt023
Anyway, I'm too old for wheelies........

Hmm .... now I'm not so sure. I was looking at an early fork design where the pressure chamber seems to be remote from the seals. I'll defer to Neil's wealth of experience on this. I expect he'd know.

I've been using a new go-faster Chinese chip oil - "Flying tonight"
