Terry's FLX saddle offers the best in split saddle engineering. Perfected by our saddle partners at Selle Italia in Italy, this novel approach allows the saddle a small degree of additional flexibility in addition to relief channel comfort. If you find the Terry Butterflies are too wide or too padded, this saddle line is an excellent alternative. We recommend the FLX to elite riders who prefer a lightweight, lightly padded saddle, but with the Terry comfort factor dialed in.
