    Clockwise left pedal. Anticlockwise right.

    A decent pedal spanner helps and extra leverage - I have a garden rake that goes over any spanner for extra powerrrrrrr

    Put the crank arm at 90 degrees to the ground, put your foot on the pedal to work against and pull up on the pedal spanner/hex key. I've never had a pedal which did not succumb to this method.

    Thanks Chaps

    Managed to get them off , but it looks like someone had put locktight on the threads as there is a blue powder/dust on the threaded area , is this normal ?

    Cheers, Ian

    Normal, no, damn stupid, yes!

    Make sure you use copperslip on the new ones!

    Grease is better than nothing and you don't need a lot of force on the pedals.

    The precession effect on the threads mean they self tighten, so while it's advisable to nip them up pretty firmly, there really is no need for loctite.

    While copperslip is best, grease should help prevent moisture and other debris getting into the threads and seizing them, although on my commuter it still needed a bit of heat to remove the pedals that had been on for about 5 years and circa 5500 miles.

    Worth reading up about precession, its counter intuitive as youd expect the pedals/bottom bracket cups to undo.

    I had the same issue with the gf's old pedals on her old bike before she got her new ones. Watched a video to work out which way and then had to use long spanner and a hammer carefully, literally took 20 mins! They were tight AF! Probably better ways to go about it but I didn't have anything, the sound of a large leverage pole sounds MUCH better for sure!

    Not sure why people tighten pedals up really tight there is no need and only causes hassle later.

    The one thing though make sure there is plenty of grease on the threads, I had a superstar pedal axle seize on the crank arm even though I had greased it well.
