1997 Haro Monocoque
1997 Haro monocoque. aluminium box frame, these bikes have a funny ding when you knock on them.
- Was one of the most expensive BMX frames when released in late-1996
- Voted the #1 frame in the world (Ultimate Bike contest) in 1997 by the readers of BMX Plus! magazine
- Made in the U.S.A. (San Luis Obispo, CA)
- Debuted on May 24, 1996 the 1996 ABA Spring Nationals in Santa Clara, CA (Day 1)
- Had a rather steep head tube angle that created a more responsive frame
- The “front triangle” was consisted from two aluminum shell-stampings that were welded lengthwise together
- Created a sleek look by routing the rear brake cable through the hollow monocoque front end - internal cable routing
- Featured a recessed area in the middle of the monocoque shell to add to the overall strength
- Required over 70 inches of welding to join the 1.2mm thick shells
- With the massive amount of money that was spent making the machinery used to stamp the front triangle shells, the frame was only available in one size, and it’s long
- Used an dramatically oversized seat tube - beefed up the frame's backbone and provided a wider cross-section for welding the front end
- Had a very stiff rear triangle that was made with square tubing and CNC machined "yokes" - a monostay bridge on the top (seat stay) and a bottom bracket box on the bottom (chain stay)
- Featured unique built-in chain tensioners that used an Allen bolt that was threaded through the front of the dropout to push the rear hub axle back - conventional chain tensioners pull the rear axle backward
- The tensioners also use a dropout-saver plate that is supported on the top and bottom of the dropout - there is virtually no way for the wheel to slip forward
- Used long-travel motocross style CNC machined dropouts - 1.8" of dropout travel
- Manufactured to Haro’s specs by Mountain Cycle - in a facility world-renowned for building the best monocoque-style bicycles available

- Details These were handmade (for haro) in very limted numbers and sold as frames only. Some people report this frame was $300. some bike reviews show list price was $800. (for just the frame) I would not pay that for this frame. A decal describes this bike being made with A6000 series aluminum(?), its probably 6061-t6, could be a marketing ploy. The welds are not that good, obivious to the trained eye, many starts and stops during long weld travels and inconsistant path speed. They do have cool cnc lugs with haro logos on them.
