Race frame from Stay Strong. This is a completely newly designed frame, utilising the key features from the previous For Life models. The V4 is now also available in disc only* or regular v-brake options. Transferring the stiffness of the V1, the oversized tubing of the V2 and the race winning geometry of the V3. The V4 is Stay Strong's fastest frame ever! The frame features triple butted down & toptube, double butted chain & seat stays adding strength while saving weight. We have once again increased frames stiffness for power and speed. Stay Strong's Pro 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 upon request. The frame uses a 31.6mm seat post** which reduced weight whilst helping improve stiffness . The smooth welds also help give the all new water decals and graphics a fresh clean look. *Disc only frames have the 10mm disc hanger included. (15mm and 20mm disc hangers available to purchase). **This frame in Pro size up to Cruiser requires a 34.9mm Seatpost Clamp & 31.6mm Seatpost.
