Periscope

I recently picked up a used 2005 Co-Motion Periscope with less than 300 miles on it. Problem is that the original owner or shop installed the stoker toe straps incorrectly and the buckle scraped the drive train side crank arm pretty badly, leaving a deep groove. I am not overly concerned about the structural impact as my eight year old will be riding stoker.

I thought I would reach out on the off chance that someone out there has upgraded from the ISIS vintage cranks or someone might know where I can find a replacement arm I would be interested in any help. Let me know what you have and what you want.

Thanks,

Warren

Warren, I have a complete set of FSA SLK stoker tandem cranks that have around 2500 miles on them. I upgraded to the new Ultegra cranks. They are 175 mm and in great shape. I will sell them for $100 plus shipping costs.

You might want to try Precision Tandems, as I'm pretty sure they have a 170mm Gossamer ISIS drive-side arm without chainrings for under $100.

Thanks for the responses. I was able to connect with Precision Tandems and they had exactly what I needed. A take off arm that that was essentially new with cosmetic damage and was cheap.
