I have just purchased a 92 raleigh peak mountain bike that is in excellent condition and best of all it was only £30!. What I would like to know is it possible to fit 11/8" ahead thread less headset and forks to it?. I know the steerer tube is "oversized" but does it make it possible to do the conversion?. I did see a picture of a Raleigh Summit on the forum somewhere and I am sure it had 11/8" forks fitted, it even had a disc brake!. Just need to know if it's a case of pressing in a new headset or if it is more complicated than that?
