This product is 2nd Choice. There are slight signs of use. The function is not impaired.
Used to pace attacks up the Alpe D’Huez in the Tour de France and to hammer on the Queen K during the Ironman World Championships, the PRECISION powermeter delivers industry leading accuracy and reliability when you need it most. Through our patented 3D strain gauge technology, you have the assurance knowing that the data you depend on will help lead you to your own Yellow Jersey.
Packaged into a durable lightweight design and compatible with ANT+ and Bluetooth Smart head units, PRECISION will help you train harder and smarter. A ride-ready PRECISION includes and comes preinstalled on a brand-new Shimano crank arm. These crank arms will fit bottom brackets using the Hollowtech II interface.
How does it work?
A ride ready PRECISION pod is already preinstalled on a brand-new Shimano crank arm at our factory. The moment you order, our fulfillment team will get it on its way to you, and you should be able to ride with power as soon as it arrives.
Important: You need to use the frame clearance pages to ensure there is space between your crank and frame for the PRECISION pods. Please see attachments.
What do I get?
Once your ride-ready PRECISION powermeter arrives, it just needs to be installed on your bike using the standard Shimano crankset installation process. Connect a headunit or computer, and you can start riding with power!
Warranty & Durability
Ridden through rain storms at Strade Bianche, mud filled cross country mountain bike races, and even tested amidst the salt spray of the ocean on Oracle Team USA's America's Cup competitors, you can be assured that your 4iiii powermeter will be as tough as you are and is backed with an industry leading 3-year warranty. All 4iiii powermeters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.
If the weather or climate make riding outdoors tough, your 4iiii PRECISION powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, TheSufferFest, Rouvy, and more. Simply use your favourite app's connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding!
Gold Standard In Accuracy
4iiii powermeters have had their gold-standard +/- 1% accuracy independently verified by leading scientists at the Locomotion Lab at the University of Colorado. This lets you plan your training, pacing, and racing with confidence, knowing that your equipment is measuring your true power output.
Dual-Channel ANT+ & Bluetooth Smart
4iiii powermeters communicate their measurements over both the widely-used ANT+ and Bluetooth Smart radio standards, letting you read and record your power numbers on an enormous catalog of headunits, sportswatches, smartphones, and computers.
3D Power Measurement
When you put force through your pedals or crank, it doesn't just bend the crank - it twists and flexes in all 3 dimensions. 4iiii's patented 3D power measurement system measures this multidimensional strain, so you can be confident that your unique pedal stroke is still measured accurately no matter your riding conditions.
3 Year Warranty
4iiii powermeters are waterproof, durable, and designed to be accurate and precise even in the harshest conditions. Because of this, an industry-leading 3-year warranty is offered.
