It's no easy feat to improve upon a power meter that was already one of the lightest, cheapest, and most accurate on the market, but the 4iiii Precision 3 has done just that. Regardless of whether you are contesting Iron Man triathlons, stages of the Tour de France, or town-sign sprints during the weekend club run, the Precision 3 offers truly world-class technology, at an affordable price point. SIMPLY CONNECT As you’d expect, the 4iiii Precision 3 is feature packed and easy to install. It incorporates Bluetooth and ANT+ connectivity, so you can connect it to your choice of bike computer or indoor trainer. Pair it with a compatible device, and it'll work with a plethora of indoor training software, including TrainerRoad and Zwift. Installation of the device is as simple as installing any Shimano left-side crank arm. The power meter arrives pre-attached to the Dura Ace 9200 crank arm, all that's left for you to do is install it on your bike, as you would a regular crank arm. Once installed, follow the set-up instructions via the app, available on iOS and Android. With the app you can also update the firmware, check battery status, and calibrate your power meter. LONGER-LASTING BATTERY In the previous iteration, the Precision already boasted a respectable 120-hour battery life. For the latest version, this has been increased to an industry-leading 800 hours. Operated by a simple to replace CR2032 battery, even the most dedicated cyclists will rarely need to replace the battery. Incredibly, despite this increase in battery life, the casing that houses the device is almost half as thick as previously, making it compatible with even more frames. Handily, LED lights have been added to indicate battery life, connectivity, and calibration status.

Over the years, 4iiii have established themselves as a reputable player in the industry, and are well regarded for the accuracy and reliability of their devices. As you'd expect, then, the Precision 3 is no different.

So named due to the 23 large ventilation ports, the Project 23 ABS Full Face Helmet features a whole host of materials and technologies to ensure you're head gets the finest protection possible while offering an incredibly low weight of just 860 grams and great value for money for a hard-shell lid. It's at home on the Enduro circuit but is also brilliant for your trail days. Start With Protection As with any mountain bike helmet, it's core function is to keep your head safe when you take a slam. And to this end, 7iDP chose a sturdy ABS hardshell construction over the EPS foam core rather than in-moulding a light outer to a foam core, as can be found on most trail helmets. This makes it superb at absorbing impacts without excess weight, achieving it all without compromising safety while also offering great value for those of you on a tighter budget. The CRV (crash Release Visor) is also designed to snap away in the event of a crash, reducing forces on the neck and head. It simply snaps back into place too, rather than uses bolts. Keep Cool. Keep Riding. While you want to know you'll be covered in the event of a spill, hopefully, most of your time is spent riding, not dusting yourself down after a slam. And to this end, 7iDP haven't forgotten about comfort. The 23 vents make this the most ventilated hard-shell full-face helmet currently available. Pick up speed and enjoy the rush of cool air. The Goggle Dock makes space for your eyewear and keeps them in position when you're riding hard. Full-face Enduro mountain bike protection meets lightweight and innovative design, making this a brilliant all-rounder for all your rowdy mountain biking outings.
