BC40 SRAM XO Eagle - Dark Blue/Coral

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.

We try our best to accommodate custom options. Please reach out to us and we will let you know if it is possible and give you a quote.

Yes, all of our bikes and models ship set up tubeless with Orange Seal sealant.

No, since everyone's proportions are different, we prefer to have a human involved. Please email our fitting team at support@alliedcycleworks.com and we will custom fit you via your measurements and current bike geometry.

The BC40 is set up with and designed around 120mm travel front and rear. It can also be set up with 110mm 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.

The BC40 frame was designed, prototyped, and fully tested in-house at our factory in Bentonville, AR.  The carbon layup and molding on the front and rear triangles take place at an external factory based in Asia. Each raw carbon part produced at the external factory undergoes a rigorous in-house quality inspection and paint preparation to ensure the highest standards. The suspension link, brake mount, and DUET stem are manufactured fully in-house at our Bentonville location. Finally, the frame is custom-painted and assembled to each customer’s unique order at our Bentonville facility, and goes through a final inspection and test ride before leaving the factory.

29x2.4” on all sizes.

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

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

Like all ALLIED bikes, the BC40 is built to customer order. Each rider can choose from one of our many base and logo color options. Additionally, we hope to offer a couple of our athletes’ custom paint jobs as limited editions.

See attached for the BC40 Geo and Frame Specs.

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

Please reference our BC40 Saddle Height Guide for minimum and maximum saddle heights per dropper length.

We spec it around the Chris King Dropset 3:

• 41mm 45x45 upper bearing
• 52mm 36x45 lower bearing

Two! One of any size on the downtube, and one 21oz or less on the seat tube. Double-check that your lid doesn't rub the shock mount and the base doesn't touch the downtube—you don't want it to rub your beautiful paint!
