Let me start by saying this mount SOLVED my triathlon bike's cockpit clutter. As someone who juggles a Garmin computer, GoPro, and front light during races, the Bar Fly 4 TT became my Swiss Army knife.

The GOOD: Installation took me under 3 minutes - just slide it onto my 24mm Deda aero bars (finally a mount that fits!), use the included rubber shim to prevent scratches, and boom - instant real estate between my extensions. The Garmin mount holds my Edge 1030 securely even on cobblestone roads (tested during a brutal training ride).

The BAD: That $32 price tag stings for molded plastic. My torque wrench incident mirrored another reviewer's experience - overtightening WILL snap the hinge. Pro tip: finger-tight plus quarter-turn only!

ANNOYING QUIRK: The GoPro mount's backward Allen screw placement is downright frustrating mid-ride. Why not use thumb screws like every other GoPro accessory?

PERFECT FOR: Time trialists needing multi-device mounting on wider (22-24mm) aero bars. The included adapters for Wahoo/Polar/etc are nice, but let's be real - most buyers are Garmin users.

FINAL VERDICT: 4/5 stars. It's overpriced but currently the ONLY reliable solution for modern TT bar setups. Just treat it gently and it'll keep your electronics exactly where you need them - in your sightline, not your stem.
