Why did ALLIED make this bike?

Quite simply, we love mountain biking. It’s in our DNA, and we are lucky enough to live/work in the mountain bike mecca of NWA. Just like the ECHO and ABLE, we built a bike that we wanted to ride, inspired by our local terrain and the demands our athletes require to perform at the highest level.

Where is the frame made?

The BC40 is designed and built 100% in-house at the ALLIED factory in Rogers, AR. We machined the molds, tooling, and suspension linkage in house, and every piece of carbon is hand laid by our expert lay-up team.

What travel does the BC40 have?

The BC40 is set up with and designed around 120 travel front and rear. It can also be set up with 110 or 100mm options by utilizing different fork and shock options. You will see our athletes using the BC40 in 100mm travel mode for races like Leadville this summer.

What is tire clearance for the BC40?

29x2.4 on all sizes.

What part spec options are available on the BC40?

We will offer options with SRAM, Shimano, Fox and RockShox so each rider can build their own dream bike.

How much does the BC40 weigh?

Target frame weight including Sid Luxe Ultimate is 1950g/4.3lbs for size L; final weight will vary depending on size and paint option selected.

How will it be painted?

Like all ALLIEDs, the BC40 will be built to customer order and each rider is able to choose from one of our many base and logo color options. In addition we hope to make a couple of our athlete’s custom paint jobs available as limited editions.

What is the Standover Height?

All frame sizes have a 705mm (27.8") standover measured from the center of the BB to the top of the top tube.
