My shifter cable snapped at the bar-end shifter, and I learned that the spare cable I carried was too short to reach the derailleur. It turned out to be surprisingly difficult to knot two cables together to make a longer one! On my first long-ish tour (SF to Vancouver Island BC), I was riding my first custom bike -- a sport tourer with pretenses of being a racing bike. I wanted it to be light, so I bought an Everest superlight chain and ER Pedals (Ti). One pedals broke while riding through Coos Bay Oregon, and I woke up a shop owner to sell me another pair. The chain broke near Raymond Washington, and I patched it back together on the road and then bought a replacement at a Coast to Coast store -- back when all road chains were the same. I was on a tour in the Sierra and broke a bolt in an Avocet seat post and found a replacement at a tiny lake resort near the top of Carson Pass -- a guy had some spare outboard motor parts, and I found a bolt that worked well enough to get me home. Riding across the US, I had one pedal that clicked like crazy. I opened it up and found that there was no keyed washer between the locknut and the cone. In fact, there was no keyway in the axle -- so I filed one and got the proper washer from a shop in Missoula Montana -- from Sam Braxton. http://www.classicrendezvous.com/USA/Braxton.htm I've had all sorts of things go wrong on tours, and the remarkable part was fixing it or finding someone to help, even in the middle of nowhere. Well, although it wasn't my failure, one of my riding buddies had a challenging failure when we were doing a tour across Ohio. It was Labor Day, and absolutely everything was closed in remote western Ohio - not that there was much on our remote western Ohio route that would have ever been open. Anyway, we were JRA when he said "Something's wrong" and began dropping behind me. We heard weird clunking noises coming from his bike. turned out his SunTour freewheel had somehow broken at the outboard end, and was sprinking tiny ball bearings all over the asphalt. The body of the freewheel was wobbling badly and the pawls were only sporadically engaging. And this was Day 1 of our ride. We picked up quite a few of the little ball bearings, but it was obvious we'd never find enough of them - and how to repair the freewheel even if we had? But the residents of the only house on that road happened to come outside at that point, and we were soon in their garage/outbuilding borrowing tools and puzzling over the problem. They found some electrical wire with plastic insulation that was about the same diameter as the bearing balls. We used the bearings we had to fill the inner race, and the well-greased wire to fill the outer race. I found that if we took out all the shims, the outer cone of the freewheel could catch just enough threads to hold the mess together. The only problem was it was no longer a freewheel. My friend now had a 15 speed fixie. So we pedaled on, something like another 50 miles that day with zero coasting, and more the next day until we came to a shop that could sell him a freewheel. He was a tough old guy, about 20 years older than I was. I admired his ability to crank out those non-coasting miles. -- - Frank Krygowski |

I don't think recereational or sales promotional drugs are allowed during Pesach. And speaking of Passover and technology: https://www.youtube.com/watch?v=baQfqoZrEvI Very cool. Thanks. Please note that there may be a connection between the ancient pyramid builders and cycling. One of the topics of endless discussion is how the pyramids were originally built. The most common suggestion is that they built a huge ramp on one side and dragged the stones up the ramp to the top. There are lots of problems with this idea[1][2], but for the sake of this discussion, I'll assume that this was how it was done. Now, pretend you have this huge ramp and Pharaoh has his chariots. In order to handle the weight of 2+ ton stones, the ramp has to be very solid and smooth. How long will it be before someone lashes two chariots together and tries the ultimate joy ride down the ramp? Could the pyramid builders even resist the temptation? After the initial learning curve and associated fatalities getting the chariots to run in a straight line, I suspect someone quickly determined it would be useful to have some way to steer it. Using two inline wheels instead of four might make steering even easier. Assuming they survived the ride, this could have been the real beginning of bicycling. Bicycling really didn't work until the roads were suitable for the relatively small diameter wheels. Roman roads were rock piles. Mediaeval cobblestone roads were worse. Dirt roads where mostly wheel ruts and mud. Large diameter wheels were needed. Only when proper paving and drainage were introduced in the early 19th century was a smaller wheel bicycle possible. In ancient Egypt, riding a bicycle over sand also had its limitations, but with a pyramid ramp, there was a compacted and flat ramp that would be perfect for the ultimate joy ride. I don't see how it could NOT have happened this way. Unfortunately, pyramid construction was limited to a few wealthy pharaohs. Their amusement ride concession probably didn't generate enough revenue to pay for its construction. So, downhill bicycle chariot riding languished until it was revived in the 1970's. You read it here first... Chag Sameach (happy holiday).
