Merrithew High-Precision Gearbar Upgrade

Merrithew High-Precision Gearbar Upgrade

Upgrade your Reformer with the High-Precision Gearbar to get finer tension control and simpler on-the-fly adjustments. This upgrade adds six distinct gearbar positions and a user-friendly, lockable adjustment mechanism so instructors and clients can set and repeat precise spring tension quickly and safely during sessions.

Benefits

• Save time during sessions — quick pull, slide and lock adjustments let you change tension without interrupting flow.
• More accurate resistance — smaller position increments let you dial in the exact tension you need for each client and exercise.
• Safer self-adjustment — a fixed, lockable gearbar and secure pins reduce the risk of incorrect installation and make independent adjustments safer.
• Better client fit — the extra positions support a wider range of users, from those needing gentle progression to high-performance training.
• Smoother teaching — audible click and secure locking give instructors confidence that settings are consistent and repeatable.

Features

• Six gearbar/stopper positions for finer incremental tension changes.
• Spring-loaded pins that lock the gearbar securely into the selected position.
• Spring balls that seat into concave spring slots to keep springs anchored.
• Full-length glide along the adjustment bar for flexible positioning.
• Simple pull-slide-pin operation for fast, intuitive adjustment.
• Audible click when pins engage to confirm a locked position.
• Position numbering corresponds directly with carriage stopper positions for easy matching.

Specifications

• Number of positions: 6 distinct gearbar/stopper settings.
• Adjustment mechanism: spring-loaded locking pins (pull, slide, pin to set).
• Spring interface: spring balls that seat into concaved spring slots.
• Movement: glides along the full length of the Reformer adjustment bar.
• Compatibility: designed for Merrithew Reformer gearbar/stopper systems (positions align with carriage stoppers).
• Operation note: disengage springs completely before sliding the gearbar; listen for pins to click and give the bar a slight wiggle to confirm engagement.
• Usage guidance: match gearbar number to carriage stopper number for general setup (e.g., 1 and 1, 2 and 2); adjust as needed for footwork, arm work and feet-in-straps to achieve the desired range of motion.
