We love seeing our wheels out on the trails — especially when they become part of a bike someone has built themselves.

400 km of gravel, and the WRMC50 is still making a great impression. 🚴‍♂️

One of our customers recently put the BTLOS WRMC50 through around 400 km of gravel riding and shared his feedback with us.

From the finish and spoke tension to wheel trueness, tire mounting, weight and overall ride quality — he was impressed across the board.

His words:
“Everything is top-notch, and the ride quality is wonderful.”

This is exactly the kind of feedback we love to hear — not just how a wheel looks on paper, but how it feels after real miles on real roads.
