LEADVILLE RECORD HOLDER

If you want to make an entrance, we suggest following Kate’s Leadville playbook. In her debut at the world-renowned event, and fresh back from an injury, she obliterated the course record with a commanding solo effort on her She Sends Racing BC40. Jaws dropped, eyes weeping, hearts full—truly an effort of a lifetime. Could you do it, too? We know BC40 is up to the challenge.

MORE GIRLS ON BIKES

Kate’s on a mission to empower more girls on bikes, and now you can too on this limited-edition BC40. Not only will you rock the sparkle watts on the trail in Kate’s She Sends Racing colors, but when you buy, we donate a portion of each sale directly to her foundation, expanding opportunities for women and girls in mountain biking. That’s a mission we’re all ready to send.

COLOR-MATCHED FORK

Send it with an upgrade to the 120mm color-matched RockShox SID Ultimate Flight Attendant fork for the full She Sends Racing performance package. Automatic adjustments between Open, Pedal, and Lock settings let you focus on the ride while the fork does the work for you.
Geometry

For optimal performance and control on fast and technical tracks, BC40 uses a slack head tube angle and a long front-to-center measurement. The result is geometry that positions the rider further behind the front wheel for world-class ride quality and predictable handling, no matter how hard you push it.

Frequently Asked Questions

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.

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!

Ride like Kate

Kate’s a beacon of positivity and female empowerment on the singletrack, and riding her She Sends Racing BC40 team colors spreads that message from the basins to the peaks. Whether you’re charging hard at your next race or getting into weekend shenanigans with your crew, you’ll be sending it, as she knows you can.

About the She Sends Foundation Mission:

The She Sends Foundation is on a mission to connect, support, and inspire women and girls through the sport of mountain biking. We believe mountain biking is more than just a sport—it’s a powerful tool to help women build confidence, resilience, and community. And while the women’s sports movement has experienced dramatic growth and renewed social and economic support, there is still a significant gender gap in the sport of cycling. 

We want to change that. We are committed to increasing participation in the sport, expanding development opportunities at every level, and, most importantly, encouraging women and girls to take risks, push their limits, and discover what they’re capable of—on and off the bike.

I could not be more excited to launch my custom BC40 colorway with Allied. Every time I ride, this bike gives me a little sparkly reminder that my love for this sport is about so much more than any start or finish line. I hope that it inspires more women and girls to get out and ride, to be as joyful and sparkly as they are badass and driven, and to go after their dreams with all they’ve got. I am so grateful to Allied for their partnership in this dream and for their willingness to meaningfully support our vision at the She Sends Foundation!
