Hi,
I have a Truvativ Giga Pipe ISIS Bottom Bracket with M12 thread size. I need help because I need to buy a tap to re-cut the thread as the crank bolt (which thread is fine) won't catch onto the thread of the bottom bracket due to the start of the thread in the bottom bracket being damaged. I have looked for a while to try and find out the the pitch of the M12 thread. The only result I was able to find was, "M12 x 1.75mm". I am not sure if this is correct so I need help because my bike is un-rideable!
Thanks, Stevey
