## Customer Reviews

### ⭐⭐⭐⭐⭐ Must have on any clip-on aero bars!
*by S***Y on August 22, 2020*

This product is a must-have on any clip-on aero bars! Riding with it is so different when you can switch gears easily without changing positions. Setup was relatively easy and quick on a DI2 (Ultegra), which took about 45 minutes, including removing the bar tape and putting it back. You can unscrew the cap and move the wire to go out from within the mounting screw and then internally through the tube. The cable is long enough to get to the DI2 shifters' junctions on the handlebars, and the mounting screw is durable and sits firmly on the aero bars. My only complaint would be the price.

### ⭐⭐⭐⭐⭐ Plug, play, and race.  Applause.
*by M***L on October 24, 2015*

This revolutionizes time trialing. Easy to connect -- don't buy the larger junction box until you've confirmed your plugs under the brake hoods are already used. In my case I just plugged into the unused ports, retaped the bars, and everything worked. I then raced with them 440 miles down the Natchez Trace Parkway and even with a foggy brain shifting was simple and convenient. Bravo.

### ⭐ One Star
