Literally wrenching the pedals off my Centurion Ironman to replace the platforms with Look pedals. Apparently the previous owner installed the otherwise nice Wellgo platforms without greasing the threads and used a hydraulic wrench to weld the steel and aluminum.
I'm having to disassemble the pedals on the cranks. I managed to get one pedal off but I'll need to find a shop with a bench vise to get the other.
So, my first foray with clipless will be delayed a bit. Unless I get impatient and try the new pedals and shoes on my Univega hybrid.
