There are double sided pedals, clipless on one side and flat on the other that allow riding with clipless shoes or conventional shoes (or maybe even barefoot :-) See Shimano A530 for an example. -- Cheers, John B. |

I made a joke BTW. Replace all your current shoes with shoes with SPD cleats en put SPD pedals on all your bikes and your problem is solved ;-). Lou |

I think you one of them. I'm not. I have one bike with platform pedals and every time I use that bike it feels like my feet are never at the right position. All other bikes have clipless pedals. I use Speedplay, Look and SPD pedals. Three kinds of pedals is one of the reasons I have so many shoes. I think I will phase out the Speedplay pedals. For my wide feet it is a pain in the ass to get good shoes for those pedals (choice is limited for the 4 screw mounting). The current Speedplay shoes and pedals are almost worn. YMMV. Lou |

What is that triangle-mounted generator and can one still buy those? In web links all I could see was a rear-mounted bottle dynamo. http://www.jimlangley.net/ride/ReneHerseBicycle.html that'd be it. In the olden days when I was a sprat, the tubes from the seattube back were called "the rear triangle." From the seattube forward was the "front triangle." The seattube managed to be a side of both triangles. I haven't kept up on what the young 'uns of today call it. In my reference, generators mounted on the seatstay or chainstays would be "rear triangle" mounted. Because the frame is the ground (earth on the east side of the Atlantic), a single wire ran through the frame tubes. It connected to a carbon brush in the head tube, which me contact with an insulated ring on the steerer tube. A wire from that traveled through the front rack to the headlight. Something similar could be done through the handlebars to the frame and then to the derailleurs. Some years back Mavic used the rotation of the jockey wheels to drive actuation of the rear derailleur, the shifter button on the handlebars acting as a release. I don't recall offhand what they did with the front derailleur. It was not 100% reliable. There was a famous moment of Bjarne Riis hurling his malfunctioning Mavic-equipped TT bike in frustration at the TdF and that was the end of that product. Chris Boardman made it work pretty well, though. Of course nowadays having a single chainring up front and a huge-range cassette is common, so only one derailleur would be necessary (Ritchey tried to market that 25 years ago as the 1x9 system and it didn't catch on; Bianchi marketed 700C mountain bike wheels and that dodn't catch on either. Everything old is new again). I have looked for roller dynamos to mount in the triangle but they seem to have vanished from the marketplace. The only ones I saw were expensive used or NOS versions, often from unknown sources. I have a Sanyo BB generator on one of my bikes- very smook, low resistance, quiet. I did have to overhaul it once with instructions from Andrew, probably will have to do that again in another 30 years. For known sources, contact Mr. Muzi. He's listed a Union BB generator on his site for years. Otherwise eBay. The Sanyos pop up there from time to time, often NIB/NOS. The battery I have on the road bike has sufficient capacity for my longest rides but a roller dynamo would allow me to mount a much smaller one. Yep. And a convenient backup in case the battery is flat. Any 6v 3W generator will power a nice Schmidt or B&M LED 100 lux headlight plus a taillight. Great range of choices available these days for any set of preferences. |

Then one sunny day it don't shift no more and the display bluntly scrolls "An irrecoverable error has occurred. Please can 1-800 ..." :-) LOL! Funny because it's true. "Hang on, dudes, I have to reboot my bike." Almost. IIRC a guy had to bring his bike back to the shop because new software had to be loaded to cure some suboptimal shifting behavior. In the good old days pliers, wrenches and 15 minutes in the garage sufficed, as it does on all my current bikes. I just had another experience with "modern" hardware. After we got home on Monday night a high-falutin pressure assist toilet was constantly running. Can't wait to get the next water bill. So I checked it. Instead of replacing a $2 flapper in about two minutes now you get to replace a $40 cartridge that is in itself not serviceable, as in glued together. The cartridge, of course, refuses to come out as best as it can. Do they use marine grease in the assembly process? Of course not. That would make service too easy. Takes raw force, always worrying something will go ka-crunch and blood runs from your knuckles. To diagnose the problem you also have to take off a pressure reducer, clean a sieve, open and clean an air vent. Long story short, $40 and an hour later it works again. For a while ... Oh, and then a few years ago we got a recall notice saying these things can explode and that a rework kit had to be installed on all of them. After which the flush was ... underwhelming and now you need two 1.6 gallon flushes versus one 3 gallon flush on the old toilet. Progress. Indeed. ... then I'd probably think about brifters again (this doesn't necessarily mean bluetooth or something like that; I think it would be easily possible to connect an electrical circuit through the frame to control the derailleurs.

And ground went via the bearings like it does in most European dynamos set-ups? That was always a sick concept. I don't think in automotive anyone would let a blooper like that pass a design review.

Everything old is new again). I have a MTB cassette on my road bike. Once reaching a certain age that is really nice when you live in hilly terrain. Unfortunately no granny gear up front so on routes with steep hills I just take the MTB. Pavement wears the rear tires fast but I can get good Thai tires for around $20.

Great range of choices available these days for any set of preferences. For now I'll leave it all on Li-Ion only. They pack so much energy that it lasts well through my usual trips which are rarely longer than 5h riding time. Some day I might experiment with solar. I saw that on a serious MTB, a couple that was preparing for a multi-week longhaul trip. -- Regards, Joerg http://www.analogconsultants.com/ |

Yet that was and maybe still is standard fare on most dynamo-equiped bicycles. I agree that grounding via the bike frame is a bad idea. But it's always been possible to run a two-conductor cord and ground things properly, which is what I've done at least since 1980. And AFAIK all hub dynamos have always used proper grounding through a two-conductor cord. -- - Frank Krygowski |
