FAQs

What type of shoes are compatible with the Shimano Saint M821 pedals?

These are SPD pedals, so they are compatible with any cycling shoes designed for the SPD cleat system. For optimal performance and grip, Shimano recommends pairing them with their AM or GR series shoes.

How do I adjust the tension on the pedals?

The pedals feature adjustable entry and release tension. You can adjust this using a screwdriver on the side of the pedal body. Refer to the product manual for specific instructions on finding and adjusting the tension screws.

Can I use these pedals for general trail riding or XC?

While they are very durable, their primary design is for aggressive downhill and enduro. For XC or less aggressive trail riding, you might find lighter-weight SPD pedals more suitable. However, they will function correctly.

How do I replace the grip pins?

The grip pins are screwed in from the back of the pedal body and are replaceable. You will need an appropriate tool to unscrew the old pins and install new ones.

What is the weight of the Shimano Saint M821 pedals?

The Shimano Saint M821 pedals weigh approximately 546 grams per pair.

Do these pedals come with cleats?

Typically, SPD pedals are sold without cleats, as most riders will already have their preferred cleats or shoes with cleats. Please check the product packaging or description at the point of purchase to confirm if cleats are included.

How often should I service the bearings?

The pedals feature sealed cartridge bearings designed for low maintenance. Service is generally only required if you notice play, stiffness, or noise that cannot be resolved by cleaning. Consult a qualified bike mechanic for bearing servicing.

Troubleshooting

Difficulty clipping in or out

Check if your SPD cleats are clean and properly aligned on your shoes. Adjust the entry and release tension settings on the pedal to a lighter setting. Ensure the pedal mechanism is free of mud or debris.

Pedals feel loose or wobbly

Check that the pedals are securely tightened into the crank arms. If the play persists, the internal bearings may require servicing or replacement.

Grip pins are not providing enough traction when unclipped

Ensure the pins are screwed in fully. Try adjusting the height of the pins if your model allows. Consider replacing worn pins with new ones.

Pedals making noise

Clean the pedals thoroughly. Check that all components are securely tightened. If the noise persists, it might indicate a need for bearing maintenance.

Pros and Cons

Pros

  • Exceptional durability for aggressive riding styles.
  • Secure and stable connection with SPD cleats.
  • Good grip even when unclipped due to adjustable pins.
  • Slim profile offers excellent ground clearance.
  • Reliable performance with low-maintenance bearings.

Cons

  • Requires specific SPD cycling shoes for optimal engagement.
  • Can be heavier than some minimalist flat pedals.
  • Pins are replaceable but require specific tools for maintenance.

Setup, Compatibility & Care

Setup:

  1. Ensure your crank arms have standard pedal threads (left-hand thread on the non-drive side, right-hand thread on the drive side).
  2. Apply a small amount of grease to the spindle threads before installation.
  3. Thread the pedals into the crank arms by hand to avoid cross-threading. The right pedal (drive side) is marked 'R' and threads clockwise. The left pedal (non-drive side) is marked 'L' and threads counter-clockwise.
  4. Tighten securely using an 8mm hex wrench from the back of the pedal or a pedal wrench on the flats.
  5. Adjust the entry and release tension settings using a screwdriver as per your preference. Refer to the manual for specific instructions.
  6. If using the grip pins, screw them in from the back of the pedal until they are securely seated.

Compatibility:

  • These pedals utilize the SPD (Shimano Pedaling Dynamics) cleat system. Compatible with all SPD cleats and shoes.
  • Designed for Downhill (DH) and Enduro mountain bikes.
  • Compatible with standard crank arm pedal threads.

Care:

  • Keep the pedals clean by wiping them down with a damp cloth after rides. Avoid high-pressure washing directly at the bearings.
  • Periodically check that the grip pins are secure and replace them if worn or damaged. Pins can be accessed and replaced from the back of the pedal.
  • The sealed cartridge bearings are designed for low maintenance. If you notice significant resistance or play, it may be time for a bearing service or replacement.
