Weird vintage tech thread.
Is there are so many weird designs in vintage frames and components that are even more interesting than modern stuff. I want to see what stuff is out there.
I will start.

1930-ish - First gen Vittoria Margherita. Lever is for chain tension only. Push forward to loosen chain. While backpedaling, use hand/stick/foot to move chain side-to-side to change gears. Push lever forward to retention chain.

While pedaling forward, twist lever to move chain side-to-side to change gears. After much effort. I never got it to shift gears without getting off the bike to move the chain manually. https://live.staticflickr.com/8396/8...53bc72ac_c.jpgCambio Sport by iabisdb, on Flickr https://live.staticflickr.com/8526/8...86c6b209_h.jpg1948 Frejus 146 by iabisdb, on Flickr |

do solar powered bike computers count?
from the March 1985 issue of Bicycling magazine... https://live.staticflickr.com/65535/...a4544d_b_d.jpg or maybe this marvel of engineering optimism... from the March 1982 issue of Bicycling... https://live.staticflickr.com/65535/...29049a_b_d.jpg Steve in Peoria |

I do remember seeing a picture of this bike in better condition on old10speedgallery a while back.

Very rugged, but used an oil bath instead of the typical grease. There was always a bit of oil getting past the axle seals, so oil drips were inevitable. For me, this was the kiss of death, and I installed a regular cup and cone bottom bracket again. Steve in Peoria |
Osgear did both actions at once with one lever. It was also indexed.

How many teeth would you like on your single speed freewheel cog?
Yes. I need a number. 96... There's no such th ...in six identical cogs. https://cimg4.ibsrv.net/gimg/bikefor...59683420e3.jpg |
Some of you know about the Cinelli Bivalent hub system. It was a scheme to keep the freewheel mounted to the frame, which then allowed the front and rear wheels to use the same hub. This supposedly had some benefit in terms of race wheel support or something. Or maybe less prone to bent axles? I'm really not sure.
A few photos from the Classic Rendezvous gatherings..... Most of these are of Harvey Sachs's Cinelli. https://live.staticflickr.com/7392/2...717ae0_c_d.jpg https://live.staticflickr.com/7557/2...3a6832_c_d.jpg https://live.staticflickr.com/7331/2...c5bff9_c_d.jpg https://live.staticflickr.com/7689/2...a12d46_c_d.jpg and an article by Jim Langley on the Cinelli Speciale Corsa... https://cimg7.ibsrv.net/gimg/bikefor...a6038beacc.jpg Steve in Peoria |

Not my drawing.

An early drivetrain concept for the safety bike was the shaft drive. Not a weird idea, really, but just not practical for bikes. Most used bevel gears at the end of the drive shaft. One novel technology was the Victor Spinroller. Instead of bevel gear teeth sliding past each other, the friction was reduced by using rollers for gear teeth. Not sure how practical this was, considering the many small rotating parts. It couldn't have been too bad, because CeramicSpeed adapted the idea for use in a multi-speed shaft drive bike a year or two ago.

Timex Velo-Trak wristwatch/cycle computer. I had one of these. First seen at the last (I think) Atlantic City Interbike show, it struck me as a terrific idea. Take that as proof of my status as a leading reverse indicator. I was later able to buy one for $20 at K-Mart when they were dumped. I think I used it once before it broke.

It also was a knock-off of a system made by Palladini. Ad from 1947. I believe another Italian firm and a French company or two had something similar.

All these vintage shennanigans sort of don't make SRAMs electronic derailleurless double crankset with derailleur shifting seem sane, logical.
Sram crankset patent. That being said the linked article contains this link about the Bellevue Washington based Browning Automatic Transmission. In looking adocumentation, it appears to be what the Rodriguez Disruptor is based on. R&E Cycles is Seattle based. The distance between these 2 motropolis' is about 10 miles...They've gotta be connected, somehow. I guess it goes to show that some ideas are before their time. |
