Striking Custom Crumpton

Striking Custom Crumpton

Straight out of Austin Texas, Crumpton frames are designed, built, and finished by Nick Crumpton himself, making every frame a fully custom labor of love. Have a look at this Sub 12lb disc brake road bike we just built...

Sub-12-Pound Custom Crumpton Disc Road Bike

Fair Wheel Bikes built this custom Crumpton disc road bike to 11.8 lb (5.35 kg) with a carefully selected mix of lightweight components from THM, MCFK, Extralite, Björn, Hope and Fair Wheel Bikes.

We are big fans of Crumpton bikes. Nick Crumpton builds and finishes each custom carbon frame himself, and the detail and craftsmanship have made his bikes a shop favorite.

Completed sub-12-pound custom Crumpton carbon disc road bike
A fully custom Crumpton disc road bike built to 11.8 lb (5.35 kg).

When disc brakes became standard on road bikes, many weight-focused riders assumed the change would end truly lightweight builds. This Crumpton proves otherwise. The complete bike came in below 12 pounds without losing the character or component detail expected from a Fair Wheel Bikes custom build.

Lightweight Component Details

Because each frame is built to order, the wait gave us time to consider every part of the build. The final selection combines an aerodynamic carbon cockpit, a full-carbon seating system, carefully chosen finishing parts and a lightweight mechanical drivetrain.
