Description

Things are really ramping up for the Stay Strong brand in 2026 and we're excited to join in on the celebrations of the launch of the V5.1 frames by build not one, but two custom race bikes based on these aluminium frames.

You've clocked that this Pro XXXL build and that it looks like you're getting two bikes for the price of one with the split paint scheme found on the v5.1 frames. We admit that when we saw the build sheet that we were a little sceptical on the colour combos, but there's no doubting that you won't be seen out there on the race track on this rig.

Based on the 22.25 inch frame, you taller riders will appreciate the stability of a frame of this size. With proven geometry from years of racing experience behind this brand, this build wants for nothing in the part's department. Running Stay Strong carbon rims and their Reactiv hubset, alongside a suite of Stay Strong components in the cockpit paired with SD B-84 24mm cranks, this is a bike that will take the hits and the wins.

An aluminium frame, carbon forks and carbon wheels, this is a classic winning formula that not only stands out with the black and yellow paint scheme, it'll add stability to your riding with it's long wheelbase and add to your trophy cabinet.

This bike is built and ready to ship or pick up in store. Add it to your cart and see you on the gate!
