    Kamikaze Bike Games 2013/14/15/16

Size:  104.8 KBSony loaned us a demo camera for practice and race. They liked the footage and gave both my stoker and me new cameras saying that our footage would be used in a documentary about the event. No other tandems in the Kamikaze race but there were two in the xc. We broke eight spokes delaminated and burned three sets of brake pads and turned both nine inch rotors into cones due to heat warpage. Our top speed was about 60mph.

    Uh...wow! What are the specs on your tandem? What kind of brakes, fork, etc?

    That was a great video....

    The frame was made custom by Bicycle Fabrications, it has eight inches of rear travel and eight up front as well by way of a Fox 40. The brakes are Hope mono-6ti with nine inch floating rotors, wheels are mavic 729 36 spoke laced to Chris King with steel internals. There is a Hopey steering damper, mrp/rollhoff chain retention system, full length bash guard and Sram XO 1x9 drive train.

    Any pictures of the abused rotors?

    Also, Nurse Ben was asking about Hopey use on tandems in this thread:
    Tips for managing tandem handling quirks: Seesaw, front end washout, etc...?

    Another year of the Kamikaze is in the books. Very rough and loose this year with strong wind. We had a great run on the top stage and matched our time from last year. Stage two I slipped up an put us down in a turn low on the course, we finished bruised and without a drive chain. Here is a clip from Sony showing some of the Legends and us, and a short clip that is our crash. Good fun.

    30ish, fast enough. My stoker came away almost unscathed, but I managed to bruise much of my body especially the right elbow and back of the right leg on the rear bars. My helmet bounced twice.

    2015 Kamikaze Bike Games

    Another great time at Mammoth Mountain. We warped rotors in practice, and then again in the race but this year we did not crash. The times we posted crushed last year's and gave us the top spot on the podium. Our top speed in the race was 54mph. On our way home we stopped at Tioga Pass and put some slicks on for a speed run. We had to pass three cars and took it easy in the turns but still managed to hit 67mph. Great trip, I love the Sierras. Here is video of stage 1 of our race https://www.youtube.com/watch?v=64HbnS_0whs And Tioga Pass https://www.youtube.com/watch?v=VbthJbiuMes

    The warpage was more than twice what you see when it was hot. Rotor is 224mm.

    The ride is cool, but you need a visor on the helmet. You look like a bug.

    There usually is one, but for high speed racing everyone takes them off for that small improvement in aerodynamics. I'd rather not be wearing the tights either. Next year I may try wearing the leathers and helmet that I used on Tioga.

    Kamikaze is coming up in three weeks and I have a new secret weapon. Motorcycle disc brake.

    The Kamikaze was a test as usual. A test of our teams stamina, resourcefulness, strength and nerve. Arrive at cabin 4:00am, check. Register practice and overheat rear brake, check. Spend the next 24hrs retrofitting a Yamaha R6 lever with hand made banjo bolt and adapters, check. Bleed and seal with beer can shim, check. Ready to race. The brakes were able to lock at any speed, I threw the bike sideways multiple times entering turns. We learned a lot, the final version of the system should be in place by next week. Brembo lever and caliper with steel lines adapted and offset from frame and hub. Another good run with a top speed of 54mph. KAMIKAZE! 2016 KAMIKAZE DOWNHILL - PB CREATIVE PHOTO

    Here is a rather untraditional view from my seat tube. Stage 1, loading the gondola, and stage 2 https://www.youtube.com/watch?v=5R-RcLaXn_Q https://www.youtube.com/watch?v=-h8yvGioNBQ, https://www.youtube.com/watch?v=LOYw38eBVc8. More traditional helmet cam views to come.
