Slowtwitch F.I.S.T. Certification: Bike Fitting Science Mastered by Lori and Dominique

Cyclist positioning is too often reduced to simple measurements or automated software. In reality, it’s a complex discipline where biomechanics meets athlete physics. To raise our standards at Cycles Dupuis, Lori and Dominique traveled to California to attend the Slowtwitch F.I.S.T. Workshop, a global reference in bike fitting.

The F.I.S.T. Method: A Rigorous Protocol

Developed by Dan Empfield, the F.I.S.T. (Fit Institute Slowtwitch) method doesn’t rely on rigid formulas but on a proven, dynamic protocol. Unlike static approaches, this training focuses on the athlete’s feedback combined with precise positioning coordinates.

Trained directly by Dan Empfield and his team, Lori and Dominique now master the critical variables of the protocol:

• Effective Seat Tube Angle: Optimizing hip opening to maximize power and ease the transition to running (crucial for triathlon).

• Comfort/Aerodynamics Ratio: Identifying the tipping point where chasing aerodynamics starts to compromise watt production.

• Contact Point Interaction: Fine-tuning the relationship between cleats, saddle, and cockpit for millimeter-perfect adjustments.

Expertise Beyond Technology

At Cycles Dupuis, we use laser measurement tools and advanced analysis software. While these provide essential precision, they are only decision-making aids. True bike fitting lies in the interpretation of the data.

Thanks to their certification, Lori and Dominique don’t aim to fit you into a “standard average.” They adapt Stack and Reach coordinates according to your body type, flexibility, and real goals.

Why This Protocol Improves Your Results

A F.I.S.T.-based bike fit focuses on three fundamental pillars:

• Comfort: Eliminating unnecessary tension to ride longer.

• Efficiency: Maximizing muscle recruitment, especially glutes and quadriceps.

• Health: Reducing joint strain on knees and lower back while freeing the chest for better breathing.

Lori and Dominique’s investment in this high-level training ensures that every adjustment on your bike is backed by internationally recognized scientific logic.
