Excellent customer service, fast delivery, great price.

Easy to use website, fast and efficient service, great product that was packaged extremely well and delivered in perfect condition very quickly. The 4iii is a great power crank, well constructed, easy set up, and comes with a spare battery. Done several rides now with it and my training is transformed. Setting strava PRs every ride now. Fantastic product.

Pros

  • Well made
  • Easy to fit and set up
  • Good price
