ENGIN CYCLES Single Bolt Seat Collar

ENGIN CYCLES has a workshop in Philadelphia and produces a wide variety of beautiful and functional (Form & Function) custom bikes and products using the highest precision CNC machining with machine tools so well-equipped you would never guess it was a small factory.

Almost every part of ENGIN CYCLES' handmade bikes, from the head tube to the dropouts, is machined in-house to the most exacting standards. Even with custom handmade bikes, it is common for small parts such as end sections to be sourced from manufacturers, but ENGIN strives to answer the specific needs of its customers by producing even such parts entirely in-housE

Drew Guldalian of ENGIN CYCLES is one of the most thoughtful frame builders. All of the products he creates in-house are produced with the utmost precision, while respecting the aesthetic sensibilities that modern man demands.

Seat collars fit 30.00mm, 31.8mm, and 34.9mm seat tubes and are a unique Engin style machined to our exacting standards.
30mm and 31.8mm use M5 bolts; 34.9mm single bolts use M6 bolts. The single bolt stack height is much lower than the original dual bolt design.
