As with the single-sided unit, the PRECISION 3+ PRO delivers accurate data within +/-1% using our patented 3D strain gauge technology, features automatic terrain selection, a robust battery life (up to 550 hours), and Apple Find My integration.

The inclusion of left/right balance, pedalling efficiency and torque effectiveness make for an even more detailed training and performance experience. 

Built to handle the toughest conditions, the PRECISION 3+ PRO has an IPX7 waterproof rating and is backed by an industry-leading 3-year warranty.

At just 29g and with an ultra-low-profile design, the PRECISION 3+ PRO is compatible with more bike frames than ever before. 

4iiii President and CEO Phil White said: “By adding dual-sided power measurement to our PRECISION 3+ platform, we’ve designed a product that we’re proud to have at the forefront of sports technology.

I’m proud that Specialised recognises the capability of 4iiii’s new power meter and for it to be selected to equip the flagship consumer S-Works bikes for us is the biggest accolade.” 

Building on a partnership forged six years ago, The PRECISION 3+ PRO will launch on Shimano-equipped Specialized S-Works Tarmac SL8 and Aethos models. 

Specialized’s Road Product Manager said: “In 2024, riders can find S-works and Pro Tarmac, Aethos, and Roubaix Shimano models equipped with 4iiii’s PRECISION 3+ PRO and PRECISION 3+, respectively.
