Hi everyone. I have just bought a new bike(BMC streetfire ssx) and i thought it would be a good idea to buy a pair of clipless pedals. Im niw the proud owner of a pair of shimano spd-sl pedals and shoes. but when trying to unclip from them it is very stiff and i have to really tug to get my shoe out and not fall over! I am really thinking about swaping back to flat pedals again any help or tips would be much appreciated. ATB George.
