Hello There,
I've just bought a second hand thorn raven mk1 frame with the old conical style tubing. I'll really like to build it up and get it on the road. However, its come with a set of unicrown front folks which I believe have come from a tandem.
What I'd like to do is to replace the forks with some slightly more forgiving thorn raven forks.
The trouble is, i don't know the frame size, so i don't know what fork offset I need to look for. Can anyone help?
