Classic late 80s Suntour XCD 4050 SL-4050-CH thumbshifters with large rubber levers and switchable between friction and indexed. Designed for a triple front mech and 6 speed indexed or suitable for any number of gears via friction shifting. These appeared in the 1988 catalogue and were swiftly replaced with XCE 4050 for some reason. Standard 22.2 mm clamps mean they work with any flat bars and they come in the neat Suntour box with some original cables too.
