Description

From the hundreds of conversations, and all the custom bike builds we've done over the years, there's one thing we've learned, and that's the confusion that parents encounter when deciding on the spec of a build for their young rider. This Stay Strong is what we would build if our junior rider was moving up from a off-the-foor race bike onto something more highly tuned, a little lighter and more responsive than a entry level race rig.

We ain't busting the budget neither with this one and keeping it sensible with a aluminium frame as opposed to a carbon frame. Let little Johnny prove his chops a little more before throwing him into the deep end with a carbon build, he's still probably in sprockets after all on this sized bike.

What little Johnny will love though is the dual character pain scheme of the Stay Strong V5.1 frame. Mum and dad won't miss him either on the bright orange and white bike, a real standout. 

We haven't scrimped on the spec though, with a whole bunch of Stay Strong and SD components bolted to the frame to produce a real weapon of a junior race bike. Touches like the SD B-85 cranks and SD CNC'd chainring means that this bike is well elevated above a stock floor bike. 

Like we mentioned, we've had plenty of experience building custom race bikes and with this junior Stay Strong we've done all the heavy lifting for you, and saved the confusion of deciding how to spec out a bike. Add it to the cart, this bike is built ready to ship or pick up in store.
