I have to face up to being too heavy for the seat springs on more than one pre-war bike. Anyone know if heavier duty versions are available?
Do you mean the coil springs or the mattress springs? Ron
It's the main coil springs.
If you speak to Graham at Alberta springs and send him one of your originals, I'm sure he can make some of a bigger diam wire. https://www.yell.com/biz/alberta-springs-colchester-1722563/
