I ordered that exact model and it sucks. It's small and it's VERY hard to get adjusted just right. That one has you unwrap your bar tape and attach it to your bars over the end cap. It's a pain because you can't really adjust it's position/angle after it's on the bike and wrapped up. I actually have an extra one still in the package somewhere that I'd be happy to sell to someone.

My husband bought a different one that just inserts into the bar opening (in place of a regular bar end) and then has a swivel attachment for adjustments. It works well but was expensive at about $36. I can't recall the name, but if anyone is interested, I can find out tonight. It has a similar profile to the one in the original post, but it works MUCH better (I need to order one).

I use the Mirrycle on my commuter. It sticks out quite a bit to the left of the drops, but it's a big viewing area, it doesn't vibrate much and it's easily adjustable but still doesn't migrate on it's own. I can't see it really well when I am in the drops, but I only use it when changing directions or in traffic and that's when I'm up on the hoods for visibility anyway.



Oh, and I have a bar-end shifter for my front derailluer but also wanted a mirror....so I put the shifters on the right bar instead.

I also saw a woman with this mirror rigged from her bar ends and it hung vertically to the left of her drops (with the wider part towards the top). It was nice because it didn't stick out as far as mine does.
