Both the Stages SC2 and Stages SC3 bikes share a commercial-grade frame but differ in rider features. SC2 is ideal for rhythm riders; SC3 for performance tracking and metrics.

SC2 Highlight: Black pop-pin adjustment knobs, RhythmBar™ handlebars, no console.
SC3 Highlight: Blue FitLoc™ levers, RoadBar™ handlebars, EcoSCRN console, and built-in power meter.

Each Stages bike includes a dual function pedal that offers both SPD cleat compatibility on one side and a toe cage with an adjustable strap for standard athletic shoes.

No, the Stages Display Console is only compatible with the Stages SC3, which contains the required internal generator. The Stages SC2 does not support console connectivity.

Yes, you can upgrade your Stages FitLoc Lever to the Stages Pop-Pin with Knob! You will need a 2mm Allen, a 2.5mm Allen, and a 3mm ball-end Allen wrench.

To replace your Stages Power Meter Crank Arm (which includes the entire left crank arm with integrated power meter), follow the step-by-step instructions below using the proper tools and supplies.

🔧 Tools & Supplies Needed

• 8mm Allen wrench or 8mm Allen socket with ratchet drive (recommended)
• Park Tool HPG-1 High Performance Grease
• Park Tool PW-4 Professional Pedal Wrench (or equivalent)
• Loctite 243 (blue threadlocker)
• TitanFlex heavy-duty nitrile gloves (or equivalent)

🛠️ Step-by-Step Instructions

1. Wear Gloves
   Put on nitrile gloves to keep grease and threadlocker off your skin.
2. Remove the Pedal
   Use a pedal wrench to remove the pedal from the existing crank arm.
   • Left pedal = reverse-threaded (turn clockwise to loosen)
3. Remove the Existing Crank Arm
   Use an 8mm Allen wrench or socket with ratchet to turn the crank bolt counter-clockwise.
   • This is a self-extracting bolt — it will loosen and automatically remove the crank arm.
4. Clean the Spindle
   Wipe the bottom bracket spindle's splines and internal threads clean using a dry cloth.
5. Apply Grease and Threadlocker
   Apply a thin coat of Park Tool HPG-1 grease to the spindle splines and a small drop of Loctite 243 to the internal threads of the spindle.
6. Install the New Stages Power Meter Crank Arm
   Slide the new crank arm onto the spindle so it is 180° opposite the right crank arm.
7. Tighten the Crank Bolt
   Thread the crank bolt in by hand, then firmly tighten with your 8mm wrench or ratchet.
8. Reinstall the Pedal
   Thread the pedal back into the new crank arm.
   • Left pedal = reverse-threaded (turn counter-clockwise to tighten)
9. Final Check
   Ensure both crank arms are 180° apart, the crank spins smoothly, and all bolts are secure.

For the Stages bike frame, use a diluted solution of Simple Green at a ratio of 1:30 (1 part Simple Green to 30 parts water). Spray onto a microfiber cloth and wipe the entire frame including crank covers. Dry with a clean microfiber cloth.

Stages indoor bikes use only metric tools. Never use fractional tools. For a complete tool guide, email us at sales@indoorcyclepros.com and we’ll provide access to our Stages Bike Tool Kit.

Use a 13mm open end wrench or 13mm socket with ratchet to loosen each side of the saddle clamp, make your adjustment, then re-tighten evenly. Check out our Stages saddles collection.

Use a quality #0 Phillips screwdriver to remove the tiny screws on the battery cover of your Stages Power Meter. Replace the AA batteries, ensuring the correct +/− orientation. For a tighter fit, wrap a layer of electrical tape around each battery.

Find the 5-digit ANT ID on your Stages Power Meter. While pedaling, open the StagesPower app and check for a matching device. If no connection occurs, press the reset button for 3 seconds, try again, and replace AA batteries if needed.
