Cliiiimb gives real-time Strava segment feedback

Sunglasss attachment gives audio and/or visual cues on the road

Legions of riders use the social fitness product Strava now, but the company 4iiii is hoping that the promise of real-time audio and visual feedback on Strava segments will entice Strava users to buy Cliiiimb, which attaches to a pair of sunglasses. Cliiiimb goes on sale this Friday, with the first orders shipping on November 25.

Cliiiimb consists of three things: a piece of hardware that mounts to the arm of a pair of sunglasses, an ANT+/Bluetooth heart rate strap and an iPhone app.

The Cliiiimb app asks riders to select a Strava app. Once engaged, the app then relays messages to the rider about when the segment begins, how they are doing against the selected time of another rider or their own PR, and when the segment ends

For any chosen Strava segment, Cliiiimb lets riders race against the posted times of another rider or their own previous personal best. The iPhone app calculates the progress, and the hardware lets riders know where they are in relation to the time being raced.

There are two models, the audio-only Cliiiimb is $129 (£81) and the audio/visual Cliiiimb Pro is $199 (£125). The Cliiimb Pro adds a series of LED lights at the bottom of a rider's right sunglass lens. The Cliiiimb Pro goes on sale this Friday, while the entry-level Cliiiimb will not be available until next year.

The heart rate strap is an innovative piece of the puzzle, with standalone merit, too. The Viiiiva is an ANT+/Bluetooth 'bridge', which can accept ANT+ information from various components like speed/cadence sensors, power meters and more, then also send out a Bluetooth signal. BikeRadar is not aware of anything else like this right now.
