They were in their middle teens and were doing wheel stands and side slides directly in front of me. I don't think that they understood that it is easy to take someone else down with you. |

Looking over his old website again (I really miss him), I came across his dismount technique. If I'd noticed that before, I must have forgotten it. I may just have to give that a try. -- Ted Heise West Lafayette, IN, USA |

Bit cynical about the market for such stuff. Non cyclists worry about endos or at least claim they do, but cyclists generally not in my experience, be they club cyclists or rolling though the park to work commuters, and so on. Roger, not only have I done complete endos with disk brakes, but I almost did an endo just a couple of months ago when I was riding a bike with aluminum wheels on it after months and months or riding **** poor braking carbon rims. Luckily, I realized it just before the rim brake completely locked. On really bumpy road when descending at speed you have to stand up which makes doing an endo rather easy if you're not used to the the brakes you're riding. I even did an endo on a gravel trail with my first set of disk brakes. I've done this often enough that I'm getting really good at landing with minimal injury. If your out of the saddle should be less likely, though I have a MTB background so tend to adopt that position, ie ready to shift my weight behind the saddle. Equally I’m fairly good at rolling out as well MTB, but if your doing it often then need to do something as that’s not normal. Roger Merriman |

The brake didn't work so I bravely disassembled the rear hub it to "fix it". It must have taken me a week to put it together (repeatedly) in a manner there weren't any parts left over and it actually worked :-) -- Cheers, John B. |

In fact the forerunner of today's "mountain bikes" had rear wheel hub brakes, this the so called "Repack" race. One time down the mountain and you had to rebuild the rear brake :-) The first multi-speed bike I rode was a "ten speed," probably a Huffy belonging to my brother. I was in engineering school and charmed by the bike's relative sophistication. A friend of mine in the neighborhood was a retro-grouch, although the term didn't exist then. He swore his balloon tire bomber was just as good, or would be if he just took off the metal fenders, fake gas tank, etc. I explained the benefits of two braking forces vs. one, and of gearing choice. But he was a law student and refused to accept the elementary engineering explanations. So a contest ensued. He stripped his bike, lubed all the bearings and inflated the tires hard. He may even have trued the wheels! Round one was to pedal side by side down a moderate hill and hit the brakes at a predetermined spot. I'm sure the Huffy's brakes set no records, but they did far better than his long, long skidding slide. Round two was a roughly 1 mile race on a twisty bike-hike trail in a wooded park. I out-braked him for the first tight turn, then stayed ahead from there as he spun his legs out with his only gear. In those days I probably didn't know enough to shift the ten speed out of its highest gear. I remember my legs being so tired after the mile that I couldn't stand up. (That condition repeated in later years, at the end of time trials.) -- - Frank Krygowski |
