Pedal threads on Cranks
A friend of mine just picked up an older mountain bike with really nice components.
We are taking it apart to check, clean and lube everything. The crankeset is a triple, White Industries crank, the pedal threads are in great condition but are threaded opposite of what they should be. The left pedal was on the right crank arm and and the right pedal on the left crank arm.
Nothing looks like fubar.
Was this a factory second? Is there some rational explanation for this that you can think of?

Ask the manufacturer.. CONTACT US ? White Industries
the front crank on a tandem is possible to do that, by swapping the arms on the Spindle, then sticking them on a single Bike .
the parts would not be defective but the guy he bought the bike from could have been clueless

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
Just to be sure, is the tight crank right or left hand threaded? If all is normal, pedals tighten on either crank when turned top toward the front of the bike?
It's possible that the crank is right and somebody reassembled a pair of pedals reversed. (right spindle in left body). Or, if the cranks are truly threaded opposite of normal, and in good shape, then I also suspect that they were made as "captain's" cranks for a crossover drive tandem.

My firs taught is that they are a set of tandem captain's cranks. The fact that they are triples is a bit strange, normally captain's cranks ae made without grinding, drilling, and tapping for the granny gear.
Maybe someone made a rush order for a tandem crankset and the only thing available was a crankset that had been destined to be a triple.
