    Right then, I had a set of echo ffw cranks, and I used a fixed cog on them, prob was that when I went out riding they over tightened and striped the threads, when I get my new set what could I do to prevent this?
    Would I be able to use loctite, or retaining fluid or something, because I don't want to end up with a set of stripped cranks again

    tighten your cog with a chain whip before instaling to the bike.. and when you do put them on, dont hammer on the pedals trying to tighten them be gental and push slowly on the pedal..

    I've got the same setup... I'm skeptical... and have a regular set of cranks as backup.

    i think that when i get my new ones, i am going to wack a load of loctite on them, or some retaining fluid.

    Can't weld them, the fixed cog is steel, and the crank is Aluminium.
    I have found some extremely powerfull retaining fluid, i am going to use some of that to fix it in nice and stiff.

    Brilliant solution ! When you wear out our cog you can just trow that crank away!
