    Huret spring tension

    Like someone else above mentioned, the derailleur (usually at the hanger-tab) might be bent inward some. Viewing it directly from the back, it's usually easy to see if the 2 pulleys are in the same plane with the sprockets as they should be, or bent as is common from falling over, etc. It...

    Huret spring tension

    The pulley-cage tension spring has those obvious 2 or 3 settings, but the parallelogram tension spring, which is related to the problem here, is not adjustable. However, the pivots are adjustable, and I suspect 1 or more of them are adjusted too tight--and if loosened a little, will permit the...

    Vitus 992

    One position that's just right, with easy access to the control levers, beats the holy heck out of 4, 8 or 16 that are all in the wrong place. The most expert opinion --the one that matters- always belongs to whoever's doing the pedaling. Looks great! Loads of "theft appeal," however.

    Adult Trike who made it?

    Looks like they're held on with split pins. The keyway must be for the sprocket, I guess. I'd start by applying very light (or penetrating) oil on everything that looks rusty. Then (gently if possible, to avoid spreading or mushrooming the pin end) tap out the pins with a suitable punch.

    Derailer

    That 'Problem Solvers' adapter/axle adjuster should work fine. This Shimano derailleur is an even simpler solution, and cheaper, at about $15 retail. The model pictured below is a Tourney RD-TY300-SGS. UPC # is 689228393639. The 'blurb' sez...

    Vitus 992

    I too had always heard the 'flexy' reputation, but c. 1987 rode a friend's Vitus (a 979 I think, a slightly different iteration) up Mt Evans in CO, and was very pleasantly surprised at just how stiff it seemed and how well it rode under my 175-180 lbs. My only complaint was that it seemed a bit...

    24” Schwinn Tires - ISO 547 substitute

    No way will it work. It may possibly go on the rim but will never seat up even halfway straight. Tubes are made of rubber, therefore a 540 tube works perfectly fine in 547, and also fine in skinny 559's. You can pre-stretch them like a big rubber band so they will fit into the larger...
