Thanks,
Wheels are original Sun Black Eye,notorious for being difficult to change tyres, your's should be easier, tyres are Nimbus x 1.5, a bit skinny, but they do the job.
I sold the suspension forks to cover the cost of some of the mods.
Not sure what brakes you have on your bike, but if they are disc and you change fork to rigid, make sure the forks have the bosses for them, you'll also probably need an an adapter plate to suit the brakes, don't worry it's pretty straightforward to do.
More than likely you will have to cut the steerer tube on the new forks too.
I really need to fit the mudguards and rack which I have lying around, that gap above the suspension adjusted fork really bugs me!
Good luck with your mods.
