Are the rear springs on colour coded?

I'm a big bloke and i'm thinking about replacing the spring on mine with something a bit more heafty.

Any sugestions?

And don't say loose weight !!! thats why i'm doing this

not get any more preload on the spring? i know on moutain bikes, you can get different ones, ring a sus company up they'll be able to sort something out

I think they are. Yellow is standard and Red is for people like me.

and Red is for people like me.
