Cheers guys for all your help. Just had the Fork out and it all looks good. However I did notice rub lines on the inside of the forks. The wheels I've got seem to have so much flex going on even though they have just been tensioned up at lbs friend. So I'm off to the shop to buy some Fulcrum Racing 3's. I planning to enter my first 100 miler so don't want anything giving me grief..
all the best
Simon
