The basic design of the 50.4mm bolt circle has allowed the design to do almost any job, albeit with a ton of fasteners!

The old Cyclo-Pedia catalog sold the TA cranks, and had a variety of options for chainwheel configurations....




It was only a few years ago that I finally bought a modern version, the SunXCD clone, and installed it on my Hetchins. I had been looking for a way to get some lower gears on the bike, and this seemed like the best way to maintain the classic looks.



The SunXCD cranks have a much wider Q factor than the Campy Record cranks that they replaced, but it hasn't been an issue for me. They have performed quite well!
