Note: Currently we do not have any Alter stems in stock, just the stickers. We have left the information below for those looking for information on the Alter stem.

Cino Cinelli's brother Giotto had been making steel stems since the late 1930s in Florence, Italy. They moved the business to Milan after the Second World War. In 1963 Cinelli began commercially producing alloy stems and matching handlebars and it wasn't long before Cinelli bar and stems became the choice of serious athletes and connoisseurs.

The 1A ("A" stood for aluminum) stem and Cinelli bars were first shown at a trade show at the 1960 Rome Olympics. We believe consumer production of these new aluminum stems and bars didn't begin until 1963.

Those first components had a polished, non-anodized finish. The classic clear anodization that gives Cinelli stems and bars that luxurious "milky" finish began in 1965.

Since then Cinelli has produced a wealth of beautiful, cutting-edge cycle frames and components.

The Cinelli Alter stem:

  • 6062-T6 aluminum
  • 26.0 bar clamp
  • About 210 grams (12cm)
  • Made for 1" steerer
  • 10-degree rise

Cinelli described the stem thus: An alien is landed on the Cinelli's world: its name is Alter, the openable Ahead road stem, with a hooked, aggressive profile. It is built in aluminum alloy AL 6082 T6; There is nothing superfluous in Alter; there is only what is strictly necessary. It is the expression of strength and aggressiveness. Heat treated to increase mechanical characteristics, Alter is a C.N.C. machined stem.

Listed below are stickers Cinelli made to mount on top of the stem to cover up the holes.


Cinelli Alter Stickers: For 100/110cm stems | 120/130cm stems

Mario Cippolini, The Lion King, the playboy of the peloton, was the inspiration for the stickers.  It was said that one could tell when he was moving up in the peloton by the overwhelming scent of his cologne preceding him!

An incredibly successful and flamboyant sprinter, the industrial design of the hollowed-out stem was built to resist the torque of his explosive finishes.

The stickers are intended to be mounted on top of the stem to cover up the holes in the stem. They are size specfic.
