Ratchet & Retrofriction Shift Levers

I've been messing with derailleur bikes since 1964 and I wouldn't have a problem tearing into something like those Huret levers... But frequently more wear and tear happens to bicycle components from disassembly and reassembly than from actual usage, especially with someone inexperienced with working on these things.

Huret stuff has always been over complicated. The Huret levers have 2 small parts one both sides: 1441 & 1442 which are the ratchet pawls and pawl springs. See parts breakdown in the link. They look like they could be a PIA when reassembling.

BTW, I have a number of versions of Simplex Retrofriction levers plus Campy Dopplers, Suntour Ratchets, the new Dia-Compe Silver levers and the Gipiemme GPM Chronosprint 870 BC levers.

For me, the Gipiemme work the best among classic levers when used with classic rear derailleurs up to 7 speeds, but like most of the other levers listed in the link, they're limited in the amount of cable wrap they have by the "spool diameter. Most are around 16mm.



The Dia-Compe W levers have a spool diameter of ~22mm and can easily handle 10 speed cassettes. They work smoothly but aren't anywhere as robust at the old Suntour Ratchet levers.

One other set of levers, microSHIFT are both index and ratchet. They have a nice feel and can handle up to 10 speeds but the levers and not very long and more suited for bar ends than down tubes. Also the construction is not very robust...
