Cheers For Replies My Dad has some on His Rocky Mtn XC bike , and he is getting used to them very nicely now, but it was a difernt story a month ago. I mean He can unclip them very easily now but not fast enough......... When he first got them, he was very chuffed with them, but that changed very quickley, he got me and my brother out the house "SAM, LEO COME AND CHECK THESE THINGS OUT , THERE GENIUS ,!!!" Walked outside and saw him cycling down the street with a huge smile on his face then he stopped and ballanced for a little while , then it struck him, (the floor that is) he slowly started to tilt over BAM the biggest dead leg i have EVER seen. I videod it on my old phone, may have to dig it out.! Leo
