Have a Question?

 Drivetrain, wheels, cockpit, and (especially!) paint – there’re a lot of considerations for building up a custom bike. If you’ve decided on an ALLIED but haven’t yet settled on spec and paint, then you can make a deposit on the frame to get into the production queue and buy time on the rest of those questions.

While we’re building your frame, we’ll also follow up to check the boxes for parts and pigments, including our standard paint options or a full-custom job. At current lead times, you’ll have around six weeks to finalize your ALLIED’s build and paint, after which we’ll collect the remaining balance, paint your frame, and assemble your bike.

If you change your mind, we’ll refund the deposit, so no pressure – this is just a tool to help you jump the line while working through the final details with our sales team.

Key Features

FRAMESET WEIGHT
1950 grams (Lrg)
GEOMETRY
A slacker front headtube angle for predictable handling at speed across buff and technical terrain. A longer front-to-center measurement shifts the weight of the rider further behind the front wheel for more control to maneuver at high speeds.
SUSPENSION
Designed for 120mm front and rear travel. Flex stay w/ kinematics designed for pedaling efficiency.
COMPATIBILITY
Cable management at the headtube allows for easy compatibility across components, including dropper posts and remote lockouts. Threaded BB.
BOTTLE MOUNTS
Capable of carrying 2, 1 on the downtube and 1 on the seat tube
TIRE CLEARANCE
29x2.4

Aggressive Geometry

The needs and capabilities of a modern cross country bike have completely evolved. BC40 pushes the envelope of race worthy bikes with a 66.5 degree headtube angle and 76 degree seat tube angle to allow you to optimize your weight well behind the front wheel for descending and further forward when climbing in the saddle.
