Widely considered the ultimate urban road machine, the State Bicycle Co. 4130 Road in Deep Indigo is your agent of speed in an over-complicated world. Stop blending into commuter traffic and start owning the pavement. Engineered for the rider who values analog precision and timeless aesthetics, this top-rated 8-speed strips away modern clutter while delivering maximum utility.

"The 4130 Road in Deep Indigo is our tribute to the golden era of cycling. We used double-butted Chromoly not just for weight, but for its legendary fatigue life—it’s designed to handle a decade of city riding while the analog shifting keeps you perfectly connected to the road."

THE PURIST'S DRIVETRAIN

An Analog Masterpiece
This isn't about plastic click-shifters. This is about the tactile connection between rider and machine. Classic Sunrace downtube shifting is not only more robust and easier to maintain, it keeps your handlebars clean and your focus on the road ahead.
Sense the mechanical honesty of every shift as you glide through the 8-speed drivetrain. It is a refined, satisfying experience for the rider who prefers a more involved journey.
CRAFTED, NOT JUST BUILT

Timeless Aesthetic
Every detail of the Deep Indigo edition is a nod to classic cycling heritage. See the deep, lustrous shine of the paint, reminiscent of vintage sports cars. Notice how it’s perfectly complemented by the gleam of polished silver components and white bar tape.
This isn't a bike designed by a committee; it's a curated piece of rolling art. The 28c gumwall tires strike the perfect balance—fast enough to drop the morning pack, yet wide enough to absorb urban potholes without hesitation.

4130 Chromoly Steel
Double-butted 4130 steel provides a compliant, durable ride quality that absorbs road chatter far better than aluminum.
Analog Precision
Satisfying, tactile Sunrace downtube shifting. Reliable, simple, and keeps your cockpit clean from excessive clutter.
8-Speed Performance
An 8-speed derailleur with an 11-28T cassette provides the perfect range for city sprints and heads-up climbing.
Lo-Pro Wheelset
Lightweight 700c Lo-Pro wheels paired with fast-rolling 28c tires for a classic aesthetic and quick acceleration.
Caliper Brakes
Equipped with dual-pivot alloy caliper brakes for reliable, powerful stopping power in all urban conditions.
WHY THIS BUILD MATTERS
8-Speed Dynamic Range
The 11-28T cassette paired with a 44T chainring provides explosive off-the-line speed while still giving you the climbing gears to conquer technical inclines.
Double-Butted Resilience
We use double-butted 4130 Chromoly, which is thicker at the joints and thinner in the center. This results in a frame that is 20% lighter than hi-ten steel.
Expedition Ready
This isn't a fair-weather bike. With integrated mounts and clearance for up to 32c tires, it transforms easily into a high-speed touring rig.
