Fit’s S4 Aitken Frame 21” black In-Stock

S4 Aitken Frame 4.75 lbs

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. Fit’s been working on new material for a Down Tube for the last six months so once that was finished and tested then 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, and Matte Clear
• American Made
