4iiii - LEFT SIDE PRECISION 3+ XT M8100 POWER METER 

Our most powerful unit to date, compressed into a smaller, lighter package and featuring support for Apple Find My, the PRECISION 3+ Powermeter is a proven choice of pros and weekend warriors alike. Whether you’re fighting for a Kona qualification spot, logging countless hours on virtual riding platforms or looking to better your time up the local KOM segment, you want accurate and reliable tools to unlock your potential. With up to 800 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the PRECISION 3+ Powermeter will be your trusted tool for years to come.

 

  • APPLE FIND MY: Offering the peace of mind in knowing where your power meter is.

  • BATTERY LIFE: With up to 800 hours of battery life, you won’t have to worry about changing your battery for years to come.

  • ACCURACY IN 3D: Not everyone has the perfect pedal stroke. With +/- 1% accuracy, 4iiii is the only crank-based power meter to use 3 strain gauges to measure all forces in your pedal stroke.

  • AUTOMATIC TERRAIN SELECTOR: Detects the terrain you’re riding on for more responsive cadence and power feedback/data. Ride the roads less traveled with confidence.

  • ULTRA LOW PROFILE: With an ultra low profile design, the PRECISION 3 is compatible with more bike frames than ever before.

  • LIGHT WEIGHT: At only 9 grams the Precision 3 Powermeter weighs about the same as a sip from your water bottle. Our goal is to help you get faster, not to slow you down.

  • WATERPROOF: Designed to work in our tough environment. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions.

  • 3 YEAR WARRANTY: A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all 4iiii power meters are backed by an industry leading 3-year warranty.

Not bad, not great about average.
Size: 10, Color: Navy Faux Leather
Honestly you get what you pay for with these I lucked out because of the price point. They look ok, they're not horrible, they're not fantastic, but they're doable. They hold up pretty well I've worn them to work and I walk a lot at my job so so far so good.

Insane Value Loafers
Size: 8, Color: Tan Faux Leather
These loafers are seriously impressive for the price. They’re as nice as my $80-100 pairs for significantly less. Super comfortable, great material, and holding up well 6 months later.
