The 2022 Stay Strong V4 frame is a completely ground up new design and from the Mini, up through the youth frames, into the Pro frames and including Cruiser, are all disc dedicated frames. More and more we are seeing disc only frames from leading manufacturers as we move into a new decade, and feel that this isn't just a trend that will wear out its welcome. Having a disc only frame opens up design on frames and personally, we love the sleek, high tech look of a disc set up. The Stay Strong For Life V4 Pro L Race Frame features triple butted down & toptube, double butted chain & seat stays adding strength while saving weight. Stay Strong have once again increased frames stiffness for power and speed and the Pro XL sized frames feature a tapered 1.5 head tube, BB86 bottom bracket, 10mm rear dropouts and built in chain tensioners included. With 15mm & 20mm inserts available as an option.
