No question, the original Mirrycle mirror was tops, functionally.

The size and positioning was optimal, with multi-axis friction-pivot adjustments.

Also cool was that they didn't vibrate like every other stalk-mounted mirror.

The mounting looked clean, and if the levers had rubber hoods a careful trimming gave a neat enough appearance.

While they weren't all that crash-worthy, they were fairly tough and most importantly, replacement parts were made available, a huge plus. I did repair a couple of stalk segments (using the time-honored glue/thread wrap) over the years when the threaded inserts broke free after tip-overs.

When aero levers became the norm, I adapted my Mirrycle with a 4mm high-strength bolt by drilling and tapping the slender lever housing "point". It actually worked, and I used it that way for several years on my Trek 720.

When the new model appeared, I was hoping that it would attach to the STI levers in the same manner that the reach-adjusting shims fit in, but that apparently wasn't possible and the attachment is instead under the foreward end of the hood, secured to the lever body "point".

I haven't tried the new model yet, but it has renewed my interest enough that I sourced a couple of the old Mirrycles for use on my vintage bikes. I'd say these are worth every penny.

If they haven't already done so on the current version, I would recommended a switch away from the SAE-sized hardware, with it's supplied, but not-so-common size 9/64" allen wrench.
