What sort of cranks do people have?

I have 2 left hand “tracer” cranks on my 24" and theyre just about to die.
They now need a bit of tightening every time I go out on it.

I plan on ordering a pair from but the choice it too good!


I’m running 170mm Super Maxy aluminum road bike cranks. I pulled the chainrings off of the right crank and ground down the splines. So far, so good.

Here’s a pic
