I bought a second hand boardman cb pro mountain bike. It came with no pedals (as expected) but the guy gave me some 1/2 inch screw pedals, flat basic ones.
But they don't fit. The screw diameter is way too small for the thread on (I believe you call it a crank).
The crank is shimano Fc-m542.
The bike is relatively modern. (within 5 years, at a guess).
Is there a specific size pedal I need to look for so it fits tge thread / hole?
