Okay updates. Fitting was simple enough as you can imagine, i used a fine tooth hacksaw to cut down the steerer (32tpi as i recall) using an old stem as a guide and used a file and fine sand paper to even it up.
So today first shake down ride, i was very conscious they were there not least because the front end was so light but i guess thats something i will get used to. Hard to say more until ive put some more serious milage on them.
Any questions?
