Default Do long pedal spindles exist?

This seems sort of stupid obvious to me since I thought of it about 45 min. ago, but, what's preventing the use of longer pedal spindles to clear the motor? If they exist, where do you get them? If they don't exist commercially, has anyone had them made that you know of? I am pretty sure that an extra 1 3/4" on the spindle would not harm the crank unless you were planning on doing some drastic jumping.

i know some downhill mountain bikes take a 150mm. the major thing though, if you have a frame that takes a 110mm, and you put a 150mm on it, your chain wouldn't line up anymore, because your chain side crank would be 2 centimeters out.

No, not speaking of the crank spindle as on a three piece crank, but the spindle on the pedal itself. They only protrude from the pedal far enough to get a flat wrench on them. Why not replace the spindles in your pedals rather than going for a long spindle for a three piece crank or wide one piece crank?

i don't get what you're trying to do. it's the crank arm itself that hits the engine, that's why people get wider ones, or bend them. just getting longer pedals wouldn't do anything except give you a wider stance.

but they do actually make pedal extenders that screw into your cranks and then your pedals screw into those.

Beer
They are also sometimes referred to as "knee-savers" but "pedal extensions" is more common. Icycles.com has them for about 20 bucks, I just bought some a few weeks ago.

Im using shorter cranks from a exersize bike to clear my motor,tho i would like to have wider 1 piece cranks some time. Its the crank arms that hit the motor, like Bairdco said, so just extending the peddals will not help.
