Fit Aitken S3.5 Frame Geometry
A: Top Tube Length: 20.75″, 21″, or 21.25″ – Learn what size is right for you here.
It’s sick that they included a 21.25″ frame size in there. Shout out to all of my tall riders out there.
B: Chain Stay Length: 13.6” to 13.95″ – Learn About Chain Stays Here
This is a really long chain stay. Slammed, it is 13.6″ and not many frames are this long maxed out. You will have a lot of control but it will not be very responsive.
C: Head Tube Angle: 75º
Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.
A less steep head tube gives you more control.
D: Seat Tube Angle: 71°
E: Bottom Bracket Height: 11.8″
F: Stand over height: 8.25″
This is a medium standover. A medium standover gives you more control with barspins and t-bogs. while also making whips a little easier.
Conclusion
One thing that Fit does really well is make good parts. I know I was pretty harsh on their 2020 line reviews. But the frames they make are top notch American made quality. I love the retro look of this frame. It’s also pretty light.
