Pedal thread problem

[Jim Nichols]

I bought a set of Rockbros pedals for my wife's Radrunner, but the threads seemed to not be compatible.
I thought the Radrunner pedal thread was 9/16 x 20, because you can get different color pedal sets
and they are advertised as 9/16.  The Rockbros are advertised as 9/16 x 20.   Thanks for the insight

Discovered the answer to my problem. I was trying to thread the right pedal onto the left crank.   Embarrassing but even more so, because my wife was there when I found out what I was doing..... Thanks for being a forum that puts up with newbies!

installing and removing pedals still gives me the heebees, I'm always worried I've got them backwards and I'll end up stripping threads!
