Review: Keeps the handlebars clear and holds the phone rock solid - I prefer stem cap mounts over handlebar ones because it keeps the cockpit looking clean and doesn't get in the way of my lights or bell. This one is brilliant. It replaces your headset top cap, and the aluminium clamp holds the phone completely solid, even on rough mountain bike trails. The quick attach and release mechanism is super handy when you want to quickly snap a photo without fighting with rubber bands. The orange colour adds a nice little flash of detail to the bike too. It does have a tiny rattle, but I think it's only annoying to people as sensitive as me haha. Go for it.
Review: I can see clearly now - I purchased this mount for my rearview bike camera. I live in NYC and safety is vital. This mount is perfect. Easily my best upgrade. It sticks great, no movement over hard bumps. Easy to apply to your bike.
