STOCK UPDATE 5/19/2026: We have a few RS5 bikes remaining from our initial purchase. We're anticipating existing special orders will be filled in June and ordering will reopen once more stock is available.
X-LAB RS5 -Balanced comfort and function, for wherever the road takes you.
The RS5 delivers the X-LAB riding experience in a versatile and approachable form. Built with durable X6 aluminum alloy and a semi-integrated cockpit, it offers reliable performance, confident handling, and lasting comfort.
Integrated Design, Real-World Road Bike
RS5 brings the X-LAB fluent design and engineering language to an alloy platform, with a clean cockpit integration paired with Shimano 105 performance so the bike looks and rides like it belongs far above its category.
Alloy Done the X-LAB Way
A precision-engineered alloy frame delivers the kind of durability and ride quality riders trust. The RS5 is built for long miles, daily commutes, and everything in between.
Power + Security, Standard
Branta’s in-house alloy crankset integrates a power meter and Find My tech, turning the RS5 into a smarter bike to train on, track, and own, without asking riders to bolt on costly extras.
