XXL Custom geometry for Singletrack magazine review
MODERN GEOMETRY HANDMADE STEEL 29er HARDTAIL

Carefully handmade in Reynolds and Dedacciai​ steel. The frame is a light but tough xc frame with modern geometry biased towards descending performance and fun on technical terrain.

The prototype bike weighs in at 26lbs with beefy bars and stem, plus a dropper post. On the trails It’s proven to be very swift up across and down, but above all, it’s really really good fun, capable and nimble.
