The Richie-issimo part that secures the front derailleur to the seat tube was introduced in 2004.

Salient features include being precision cast, high-style, self-seating, a well for a slice of brazing material,
and a design which allows for both traditional AND compact gears to be used on the same bicycle frame.

With the evolution of tubing diameters now including 31.7mm as a standard, the part has been reissued in
UOS (über-oversize) dimensions. These new 31.7mm conforming braze-ons will be available in the first week
of September in both steel and stainless versions.

It's the first week of September and the parts are now available atmo. Order here.
