Fit S4 Aitken Frame

Part #: 10B-FTS4A

Fit S4 Aitken Frame

Mike wanted the S4 to be as simple and classic looking as possible while using every new development in materials and workmanship available to improve on the S3.5. S&M has been working on new material for a Down Tube for the last six months so once that was finished and tested they were ready to go. The end result is a clean, classic frame that's strong and still less than 5 pounds.

S4 butted and tapered top tube
S4 stronger and more dent resistant down tube
S4 head tube (completely new design inside and out)
S4 bottom bracket shell
Single bend Chain stays and curved bridges for maximum tire clearance
Dropout with a round seat stay cut for a cleaner peg fit
Available in Matte Black, Burgundy, Tan, Turquoise and Matte Clear
American Made
