Simplex Prestige clamp-on downtube shift levers, 6th version (?). Used, $50.00

Part# SL-160

  • This lever was produced from 1973 until 1979
  • This differs from the earlier, 5th version by having adjusting barrels rather than fixed housing stops.
  • These levers may have been affixed to a higher level band because it has a sunburst "S" rather than the winged "S". Or it might simply be a very early production of this lever with a band from the earlier version. The 5th version did have a sunburst clamp. The band looks to be in better condition than the other steel parts.
  • Levers are made of Delrin

These levers are probably the finest friction (as opposed to index) shift levers ever made.

Simplex retrofriction levers have a clutch spring that give no resistance as the lever is pulled against the derailleur's spring. The rider's only effort while pulling on the lever is against the derailleur return spring. When pushing the lever back down, the clutch-spring offers mild resistance. Shifting is accurate and almost effortless.

Simplex's diagram of the levers' insides.

The Simplex design was so highly regarded that the levers were also made part of the Mavic SSC, Galli and Gipiemme groups. They also work well with Huret Jubilee derailleur systems.

The site posted this explanation and picture of the shifter clutch spring: "The Simplex Retrofriction uses a closely wound spring around a barrel as a directional clutch. Rotated in one direction the spring opens up for less friction, rotated the other way friction tightens the spring which keeps the adjustment."
