SB200 Fit Guide
Set up the SB200 to match the bike you already ride. Measure saddle height, handlebar stack and reach from the bottom bracket, transfer them to the SB200, then save them in the Bike Fit section of the Stages Cycling app.
Fit graphic
All three fit dimensions are measured from the center of the bottom bracket, the same way you would measure a road bike.

B. Handlebar stack

A. Saddle height
Bottom bracket to top of saddle, along the seat tube
20.5–34.25 in
52.0–87.0 cm
B. Saddle setback
Horizontal, bottom bracket to saddle center over the clamp. Moves with saddle height on the 72° post, ±2.25 cm on the rails.
3.88–9.90 in
9.9–25.2 cm
Fit range
Each bar shows the SB200’s adjustment range to scale. The marker is an example rider’s road bike measurement. Saddle setback depends on saddle height: the light band is the full setback range, the solid band is what’s reachable at the rider’s saddle height.

Saddle setback
The seat post runs at a fixed 72°, so raising the saddle also moves it back. B is measured horizontally from the bottom bracket to the top of the saddle, centered over the clamp. From any height, the rails add 2.25 cm of travel forward or back.

Values from the Stages SB200 Saddle Setback Chart. Between rows, setback changes about 0.31 cm per 1 cm of saddle height (72° post).
On the bike
Every fit adjustment uses the 8 mm wrench built into the frame, plus a 10 mm wrench for the saddle clamp.
8 mm frame-integrated wrench
Loosen the head tube bolt. Raise or lower the bars and read stack on the etched stem scale.
For reach, loosen the bolt under the slider. Wiggle the bars if the wedge sticks, then slide and read the slider scale.
Retighten both bolts.
8 mm frame-integrated wrench
Loosen the bolt at the front of the seat tube.
Raise or lower the seat post. New riders can start with the saddle level with the hip while standing beside the bike.
Tighten the bolt, ride, and fine-tune.
10 mm wrench
Loosen both saddle bolts.
Slide the saddle on its rails to set setback: 4.5 cm of travel, ±2.25 cm from center.
Alternate tightening each bolt until the saddle is angled correctly and secure.
