Wanted Coda 701M non drive side arm

[MMaister]

Hi,

I have got a nice Coda 701M crankset came with my F2000. Unfortunately I found a small crack on the non drive side, left arm`s root. If you have one of this left side arms in 175mm hanging around I might be interested in purchasing it.

Thanks for reading my add.

What year was your bike built?

It is a 1997.

You might get by for riding purposes with a Shimano or Sugino left arm.
Where is the crack?

Well at the moment I installed a Shimano XT 739 which matches the trim nicely, but it would be great to save the original crank, because the drive side is in good shape.

The crack is at the root of the arm, around the highest stress point under load.

Thanks for the photos. I haven't owned one of those cranks and have never seen one up close. That sharp edge and small radius between the arm and the "hub" is a logical place for a stress crack.
