I started with http://802.11junk.com/jeffl/ ands just followed the crumbs of bread :-) The photo of the Miyata seems to show the shifters mounted on the L.H. side of the down tube? Nope. The Suntour "Symmetric" shifters are centered on the downtube. https://www.google.com/search?q=suntour+symmetric&tbm=isch https://www.youtube.com/watch?v=FyR9Sezf1PM http://www.ebay.com/itm/New-Old-Stock-Suntour-Top-Mount-Shifters-Friction-Braze-On-Model-/271813768566 http://www.velobase.com/ViewComponent.aspx?ID=4cb7e658-e09e-4950-a283-2787beac2bb0 http://www.bikeforums.net/classic-vintage/514867-test-your-wits-suntour-symmetric-reassembly-challenge-pics.html http://www.bikeforums.net/classic-vintage/514867-test-your-wits-suntour-symmetric-reassembly-challenge-pics.html#post8484924 The shorter and more direct cable run between the shifters and derailleurs produces a less sloppy shift. No detents as it was designed before indexed shifters became fashionable. The location of the shifters on the downtube are fine for a "touring" bike, where one does little shifting. I like them because the location moves the shifters and some of the cable clutter away from the handlebars. The handlebar space is better suited for lighting, smartphone, camera, and horn type clutter. They're also available in a clamp on configuration: http://www.ebay.com/itm/New-Old-Stock-Suntour-Clamp-On-Model-Shifters-5-6-7-Speed-Friction-Compatible/271775719667 Yes, I have down tube shifters on two bikes in Bangkok, but mine are the braze on lug versions mounted on either side of the down tube. -- cheers, John B. |
