This series of frames are made of high quality six thousand series lightweight aluminum alloy tubing. Carefully tig-welded, they endure two subsequent heat treatments, dramatically strenghtening the alloy and releasing residual stress from welding. Each frame is then precisely hand-aligned and checked for quality on a jig to make sure it delivers flawless handling.
ADAPTED GEAR RATIO
