The Psylo Gold RC is designed for trail riding. With 140mm of travel and a stiff 35mm chassis, it is built to handle aggressive terrain, technical descents, and steep climbs with confidence.

Yes, the 35mm aluminum upper tubes provide significantly more stiffness than thinner stanchions. This translates to more precise steering and better tracking through rough, rocky sections where a lighter fork might flex.
