Marking The Cut Point
Once you know the right length, mark the cut point. Use a marker or tape to mark where you need to cut. Double-check the measurement before cutting. It’s easier to cut again than to fix a cut too short.

Tilt the saddle up or down. Find what feels best. Test the seat by riding a little. Feel the balance and comfort. Adjust until everything feels right.
