However, with consistent use – and the occasional walk across parking lots and over rough terrain – SPD-SL cleats can wear out over time. Knowing when to replace your cleats is essential to maintaining an optimal pedal-shoe connection, which directly impacts power transfer and overall riding efficiency. This guide will help you identify wear, understand SPD-SL cleat functionality, and replace them when necessary.

How SPD-SL Cleats Work

To understand when to replace your cleats, it’s helpful to know how they function. Shimano SPD-SL cleats are precision-engineered for durability and security, featuring injection-molded nylon plastic for the cleat base and a TPU coating for improved grip while walking.

Here’s how they work:

  • Attachment: Cleats are bolted onto your cycling shoes and configured for ergonomic efficiency.
  • Engagement: Vertical pressure locks the cleats into the pedal via engagement points and a spring mechanism.
  • Disengagement: Lateral rotation allows you to release from the pedals on demand.

The cleats' high-quality construction ensures precise engagement, durable performance, and resistance to wear. Depending on your walking habits, SPD-SL cleats can last multiple seasons. Riders who mainly stay on the bike will experience longer cleat life compared to those frequently walking before, during, or after rides.

  • Inspect Monthly: Make it a habit to examine your cleats monthly. Look for visible signs of wear, especially if engagement or disengagement feels less crisp.
  • Key Wear Points: Focus on the front of the cleat, which engages the pedal mechanism. The cleat should have a sharp 90-degree angle at the front protrusion. Any rounding or wear in this area affects its ability to lock securely into the pedal.
  • Color Wear: The colored TPU material (yellow, blue, or red, depending on float) provides grip while walking. When this layer wears through to the black nylon base, replacement is critical. Continued wear beyond this point compromises engagement reliability and increases the risk of accidental disengagement.

How to Replace SPD-SL Cleats

Replacing your cleats is straightforward, but it's also an excellent opportunity to fine-tune your current setup. Consider working with a professional bike fitter if you're looking to make significant changes in your cleat setup or if you've recently experienced changes in flexibility, injuries, or have shifted your cycling goals.

For riders happy with their current cleat position, follow these steps:

  • Mark Your Cleat Position: Use a pencil to trace the outline of the cleat on your shoe or take a photo to remember the placement. This will help you replicate the position accurately.
  • Remove the Old Cleat: Unscrew and discard the worn cleat.
  • Install the New Cleat: Align the new cleat with the traced outline or reference photo. Tighten the bolts to ensure a secure connection.
  • Test Engagement: Ensure proper engagement and disengagement with the pedals before heading out for a ride.

If you’re replacing your old shoes for some new kicks, Shimano road shoes feature measurement lines and degree headings to help you replicate the cleat placement from one shoe to the next. However, if you’re changing shoe models or sizes, these markings may be slightly different, so be sure to compare the cleat placement with your previous shoe setup and test out the placement before heading out for a long ride.

Maximize SPD-SL Longevity with Cleat Covers

For riders who frequently walk off the bike, Shimano cleat covers are a worthwhile investment. These inexpensive accessories protect the cleats from excessive wear, enhancing both grip and durability.

Replacing your Shimano SPD-SL cleats ensures a secure connection between your shoes and pedals, keeping your rides efficient and enjoyable. Regular inspection and timely replacement are small steps that go a long way toward maintaining performance.

A Guide to Shimano SPD Off-Road Cleats and Care

The Shimano SPD was the original off-road clipless pedal interface, the first of its kind. The system combined spring-loaded locking mechanisms with a durable metal cleat that connected the rider and mountain bike. When Shimano introduced the SPD system to the world in 1990, it completely revolutionized the experience for mountain bikers worldwide and for decades to come.

It’s become the go-to platform for World Champions from the high-intensity races of XC mountain biking, the muddy slop of CX fields, gritty gravel across the globe, and the rough and tumble tracks of Enduro and downhill racing. The fully adjustable release tension and the SPD platform has made it fine-tunable for every off-road cycling application. 

How SPD Off-Road Pedal Cleats Work

The original design of the SPD system and cleats was so ingenious that the cleat and pedal interface remains nearly the same today. However, the pedals are now lighter thanks to high-tech metals, and they have lower stack heights and better mud-shedding capabilities based on ongoing research and development. The cleats are even offered in multiple release options to suit more types of riding.

SPD cleats are relatively smaller compared to their SPD-SL road counterparts and are made of heat-treated forged steel. Here's how they work:

  • Attachment: SPD cleats bolt onto the base of your cycling shoes using two screws, creating a firm yet adjustable connection.
  • Engagement: Stepping down into the pedal locks the cleat into place via a spring-loaded mechanism.
  • Disengagement: A quick lateral twist of the foot releases the cleat from the pedal.

When It’s Time to Replace SPD Off-Road Cleats

Unlike SPD-SL road cleats, SPD off-road cleats do not feature a visible wear indicator. Instead, their performance provides the best clues about when they need replacement. Here are key signs that your SPD cleats are due for a refresh:

  • Engagement Feels Less Secure: If clipping in feels inconsistent or requires excessive force, the cleats may be worn.

 

  • Disengagement Becomes Unreliable: Difficulty unclipping or an unexpected release mid-ride can signal excessive wear.

 

  • Increased Lateral Movement: If you notice extra “float” or slop when clipped in, the cleats may have worn beyond their intended tolerance.

 

  • Visible Wear or Corrosion: While SPD cleats are built to withstand rough conditions, rust, pitting, or excessive rounding of the engagement points can compromise performance.

While mileage varies based on terrain, riding style, and conditions, a general rule of thumb is to replace SPD cleats every two to three seasons for high-mileage riders. Cyclocross racers or mountain bikers frequently riding in muddy or sandy conditions may need to replace cleats more often.

Use your best discretion and examine the hardened steel cleats for corrosion, damage, or excessive wear. When in doubt, take it to the local shop, which will be happy to examine and replace the part as necessary.

How to Replace SPD Off-Road Cleats

Replacing SPD cleats is a straightforward process that helps maintain an optimal pedal-shoe connection. Follow these steps for a hassle-free swap:

  • Mark Your Cleat Position: Before removing the old cleats, trace their outline with a marker or take a photo to ensure consistent placement.
  • Remove the Old Cleats: Use a hex wrench to unscrew the two bolts securing the cleats. If the bolts are stuck, applying a penetrating lubricant can help loosen them.
  • Clean the Shoe Sole: Wipe away dirt and debris from the cleat mounting area to ensure a secure fit for the new cleats.
  • Apply Grease to New Bolts: A dab of waterproof grease on the bolts prevents them from seizing over time.
  • Install the New Cleats: Align the new cleats with your reference marks and tighten the bolts evenly to maintain proper positioning.
  • Test Engagement and Disengagement: Clip in and out a few times before riding to ensure smooth function.

If your cleat bolts are stripped or seized, or if the cleats are extremely difficult to remove, consider visiting your local bike shop for assistance. Fortunately, Shimano SPD shoes feature a replaceable four-hole cleat nut, so even stubbornly stuck cleats don’t mean you need a new pair of shoes—unless you’re looking for an excuse to upgrade!

While SPD cleats are built to withstand rugged conditions, a few simple habits can help extend their lifespan:

  • Keep Cleats Clean: Regularly clear away dirt and debris to maintain smooth engagement.
  • Use Waterproof Grease on Bolts: Prevents corrosion and makes future replacements easier.
  • Avoid Excessive Walking on Hard Surfaces: While SPD cleats are durable, prolonged walking on concrete or asphalt accelerates wear.
  • Check Cleat Position Periodically: Ensuring a consistent cleat setup helps prevent premature wear and maintains riding efficiency.

By keeping an eye on wear and replacing cleats when needed, you’ll ensure a secure, reliable connection with your pedals—so you can focus on the ride ahead with confidence.
