Chris - I used the exterior grade 3M tape ... I've had good luck with this on other projects - doubtful it will ever come loose! I did take particular care to round, smooth, and polish the ends of the tubing - I'm watching it for chafing, but have not detected any in 90 hrs so far. I thought about putting a little heat shrink on the brake line where it enters and exits the metal tubing to add an extra layer of protection, but at that point I had everything hooked up and bled, so I didn't want to re-do it. But, so far, doesn't look like it's necessary.

IF the 3M tape does not hold-up. A couple of small drilled and tapped holes in the gear where the clips are wouldn't hurt the integrity of the gear. Say, #8-32 or a #10-32 tapped hole so some machine screws can hold the clips. But nonetheless a good clean look; nice design John....... Need to make sure the ends of the 6061 tube are well rounded and deburred.

Here's an alternative:

Piece of 6061 T6 tubing secured by .025 brackets secured to the spring gear with 3M exterior mounting tape. The tape allows a little "give". I tested this and the bracket will be destroyed before the tape comes loose!
