Splitfire:
Everything Bigger

The Splitfire is a titanium gravel bike built for riders who want more room, more speed, and more versatility from one frame. With clearance for up to 700 x 57mm tires, short 419mm chainstays, UDH compatibility, and clearance for oversized chainrings, Splitfire blends backcountry capability with fast-gravel efficiency.

Tire Clearance

700 x 57mm or 29 x 2.25 capability.

Splitfire was created for riders who want the freedom to run big, confidence-inspiring tires without giving up the speed and fit of a performance gravel bike. Larger tires add comfort, traction, and stability on rough roads, loose gravel, and long backcountry routes.

More Traction A larger contact patch improves grip on loose, wet, and uneven surfaces.
More Comfort Higher tire volume allows lower pressure and helps reduce fatigue on long rides.
More Control Big tires add stability when descending, cornering, and riding loaded.
More Versatility Run fast gravel tires, monster-cross tires, or bikepacking-ready setups.
Why Splitfire Exists

Short stays. Big tires. Big chainrings.

The elevated driveside chainstay gives the Splitfire its defining advantage: room for large tires and large chainrings while keeping the rear end compact. That combination makes it equally at home on fast gravel rides, rough mixed-surface routes, and road-wheel swaps.

Side profile of the Blackwater Splitfire

Elevated Chainstay

The driveside E-stay opens space at the tire and chainring junction, allowing a rare mix of tire volume, gearing clearance, and short chainstay handling.

Splitfire rear dropout and UDH detail

UDH Compatible

A modern universal derailleur hanger platform simplifies replacement, improves drivetrain compatibility, and keeps the frame ready for current and future drivetrain standards.

T47 Threaded BB

The T47 threaded bottom bracket combines the serviceability of a threaded system with a larger shell diameter for stiffness, alignment, bearing support, and easy maintenance.

Geometry

Progressive gravel fit with tunable handling.

Splitfire geometry is designed around stability at speed, responsive acceleration, and multiple tire configurations. The result is a titanium gravel platform that can be built for fast mixed-surface riding, rough gravel, or long-distance adventure use.
