I'm thinking of eventually trying to build up a Campagnolo component group for a tandem. Campy tandem cranks are as rare as hen's teeth and super expensive. However, peculiar to Campagnolo (or maybe for all high end 10 speed groups) the cranks when they get a bit used or the graphics come off become essentially worthless. What was a $200 crank like a Record 10-speed can be had for like $30-50. I was thinking of taking two right-side (drive side on a single) triple Campagnolo 10-speed cranks and having one of them rethreaded to take a left side pedal to use on the timing chain side of the tandem.
Who has experience rethreading a pedal like this, via a machine shop?
How well did the rethreading work?
What did it cost?
Was the pedal constantly coming loose?
Did it require the use of thread-lockign compound?
Thanks for sharing your information and experience!
