Specialites T.A. Right Crank Arm

I bought a box of parts from someone in Boston over the weekend and it included this pristine Zephyr right crank arm with mounting bolts. It is in pristine condition and it looks like it was mounted on a spindle but a pedal was not installed so it was never used. The mounting hardware is exceptionally clean and it looks as if chainrings were never installed. It has a length of 167.5mm , is BSC and marked J7. I have scoured the internet and only found one full crankset on eBay for comparison at $249. There are some references to the Zephyr in various blogs but little to go on.

I suspect that this is a rare find and have read that Grant Peterson was a fan of these cranksets but know very little other than that. If anyone on the forum can share more info or point me to info sources, that would be great. I have already posted this on the C&V forum earlier.

Thanks in advance!

I have a left arm!! But it's 172.5mm.

It's yours (for shipping) if you want it. Offer stands to anyone else as well.

Peter White Cycles lists Zephyr chainrings but I only see Carmina, Vega and Vortex cranks listed. As a TA distributor perhaps he could order the left Zephyr crank that you need unless Zephyr has been discontinued. I suspect you will also need a compatible bottom bracket assembly.

You can get the left one from Peter He is the wholesale TA distributor. (& retail) for north america.
note the 10 holes,, a 56 bcd is inside of the 74 bcd .. so 20 or 22t - 56 and 24 + on the 74 ..

Mid & outer chainrings are common 110 bcd. ..

A belated thanks to everyone for the tips and suggestions on how to find the non-drive side twin for this Zephyr right crank. Really nice offer from Terrafirma to provide a 170mm version!
Will continue searching and who knows, maybe I’ll meet the other person that is looking for the right crank and we’ll swing a deal.
