Its for a 18" frame, will try find out the correct length today. Not really bothered about the colour, the original is silver but can have them sprayed to match if no one has a silver pair.
Have two NOS GT Bologna Lites in titanium color...tad more towards champagne than silver but like you said can be lightly sanded and resprayed to match your frame. Pic is way dark due to bad light see the catalog picture for truer color.
Cheers for the forks Al didn't realise they were non threaded, not to worry they'll come in for someone else on here. Thanks for getting them out so quickly though.
