It has an integral chain tension spring and the mounting bracket is slightly canted forward to give a smoother cable run.

I do not have the knowledge base on these early derailleurs to ensure that everything is present and in working order. I have compared to catalogs when possible though.  Enjoy the lower than market value prices knowing there won't be refunds available on these. I've done my best to show everything at various angles in the photos, study them carefully.\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e","brand":"Cyclo","offers":[{"title":"Default Title","offer_id":53424657236108,"sku":"14379","price":199.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5144\/9740\/files\/portland_ecommerce_vintage_bike_parts_sale_1970s_1980s_2443__70455.1711418653.1280.1280_cdcfb1e0-fe8f-42b3-89b9-0c067322310d.jpg?v=1791038368","url":"https:\/\/swooncycles.com\/products\/cyclo-oppy-solo-rear-derailleur-3-speed-1930s-1940s-near-mint-low-miles","provider":"Swoon Cycles (Bike ReCyclery)","version":"1.0","type":"link"}
