Rainbow Jerseys On Our Home Soil!

World Championship fever has officially taken over Montreal as the best road racers in the world battle for the rainbow jersey on Canadian soil! From the punishing slopes of Mount Royal to defending champ Magdeleine Vallières leading a stacked Canadian squad, we’re celebrating the grit, history, and home-turf pride taking over Quebec this weekend.

Take Your Training to Heart 🖤
“Heart rate and power are extremely valuable metrics for any athlete, irrespective of their level, aims or ambitions. The Viiiiva completes that equation for athletes using our power meters, providing both the internal and external view of performance. It offers the same level of accuracy and durability that defines our power meters, so you can trust your data in any conditions, from racing in the rain to long sessions on the indoor trainer.” - Phil White, CEO 4iiii

As the season comes to a close, it's a great time to reflect and appreciate the successes we've experienced on the roads and trails this year. Give our latest blog a read to relive some of the memorable moments that our 4iiii athletes delivered in 2025!
