So you’ve been riding for a while, and you’re starting to feel you’ve still got plenty of pep in those legs. Maybe you’re ready to step up to clipless pedals, or perhaps you’re just curious whether it’s time to change your current setup. Either way, you’ve landed in the right spot. In this tutorial, we’re going to look at Shimano’s SPD and SPD-SL pedal systems—the two big names you hear whenever folks talk about “clipless” pedals. We’ll examine where each shines, discuss why different cleat designs exist, and walk through a few tips that matter especially if you’re in the 50-and-older crowd. Think of it as a friendly chat about how to keep riding comfortably, efficiently, and, let’s be real—without embarrassing slips on the sidewalk.
Why Clipless Pedals in the First Place
If you’ve been rolling around on flat pedals all your life, you might wonder why folks keep talking about SPD or SPD-SL. Clipless pedals (though the name sounds strange) refer to pedals that connect your shoes to the pedal body with a cleat mechanism. It’s basically the modern replacement for the old toe-clips-and-straps system once used by legends.
By “clipping in,” your feet stay securely positioned, which can help you pedal more smoothly. You might also notice better control when starting from a stop or riding on choppy surfaces. Some people find that clipless pedals make climbing hills easier because you’re pushing and pulling through the pedal stroke. If you’re worried about getting stuck, there’s a tension adjustment that makes it easier to twist and release your shoe. After a bit of practice, clipping in and out becomes second nature.
The Two Main Characters – SPD vs. SPD-SL
Shimano’s pedal family has two main branches:
- SPD (Shimano Pedaling Dynamics):
- The go-to for mountain bikers, gravel enthusiasts, cyclocross racers, and even many casual road riders.
- Uses a small metal cleat with two bolts.
- Known for double-sided pedals (you can click into either side) and outstanding mud-shedding.
- Cleats sit almost flush with the shoe’s sole, making it easier to walk around.
- Typically a bit heavier than SPD-SL pedals, but also more robust and less prone to damage if you pop them on an off-road adventure.
- SPD-SL (SuperLight):
- The road racing choice.
- Has a larger plastic cleat with three bolts.
- Single-sided entry, so you flip the pedal upward to clip in.
- Larger contact area means more stable foot support and lighter overall weight.
- Not so great for walking around because the cleats protrude from the sole.
- Favored for road riding, especially when you’re focusing on efficiency or putting in serious miles.
That’s the quick overview. Let’s go deeper into why you might prefer one or the other, especially if your biggest priority is comfort, safety, or convenience.
Walking Matters – Why SPD Might Be King for Everyday Use
Let’s be honest, if you’re cruising on your local routes and love stopping for coffee, you want to walk without looking like a penguin. This is where SPD pedals truly shine. Because SPD cleats are small and nestle into a recessed channel in the shoe sole, most of the shoe’s tread contacts the ground. You end up with a more natural walking motion—handy if you’re waiting in line at the café or strolling around at a trailhead to enjoy the scenery.
Key points:
- Less slipping: If you’re stepping on smooth floors or wet paths, the SPD shoe tread grips better than the hard plastic SPD-SL cleat.
- Less wear: Metal cleats don’t grind down as quickly. You can walk around more without messing up your cleats.
- Multiple riding styles: SPD works for road, gravel, mountain biking, commuting, and more.
For many riders over 50—actually, for any age—comfort off the bike is a serious plus. Your knees and ankles might already have a few miles on them, so any pedal system that lets you dismount and move around easily can be a relief.
Road Warriors – Why SPD-SL Might Still Be Your Choice
Of course, SPD-SL pedals have their appeal. Road cyclists—whether they’re 25 or 75—often appreciate the wide platform of SPD-SL pedals. When your entire ride is about smooth, consistent power on paved roads, the large contact area between shoe and pedal can feel reassuring.
It’s a bit like driving a car with well-padded seats and a wide footrest. It’s stable, it feels snug, and you don’t get as much foot movement. That can be great when you’re putting real effort into those pedals. Plus, the minimal weight of SPD-SL pedals often appeals to folks who track every gram on their bike builds.
Keep in mind:
- Cleat wear: The plastic cleats can get scuffed if you walk on rough pavement or gravel. They’re not expensive to replace, but it’s something to watch.
- Single-sided entry: You’ll need to practice flipping the pedal over and stepping down, which feels tricky at first.
- Less walkable: The cleat protrudes, so you’ll walk more carefully. Some riders slip on wet tiles or polished floors, so be cautious.
If you’re a dedicated road rider who rarely stops and you prefer maximum foot stability, SPD-SL might be right up your alley.
Adjusting Tension and Float
No matter which system you choose, you can tweak tension. There’s a small screw on each pedal that tightens or loosens the release mechanism. If you’re new to clipless pedals, set it to a lighter release. Over time, you might decide to dial it up for a firmer hold, but it’s personal preference.
Float is how many degrees your foot can pivot on the pedal before it disengages. Shimano SPD-SL pedals use color-coded cleats that allow different amounts of float:
- Yellow: About 6 degrees of float. Most common and forgiving.
- Blue: Around 2 degrees. Less freedom to pivot.
- Red: Virtually no float. Your foot is locked in a set position.
SPDs also offer some float, but the range is typically narrower than with SPD-SL. If your knees are sensitive—and let’s face it, many of us have knees that have put in a lot of miles—having adequate float is crucial. It’s worth experimenting with different cleats or tension settings to find the sweet spot that keeps your joints happy.
Mud, Ice, and Unpleasant Surfaces
Riding off-road or in mucky conditions calls for a pedal that won’t get jammed. SPD pedals are famous for having open bodies that shed mud. That’s why mountain bikers love them. Even in sloppy cross-country races, riders can still clip in. Gravel riders and winter cyclists also appreciate this feature. If you’re hitting snowy roads or frequently cruise through wet, muddy terrain, you’ll probably favor SPD.
But what if you’re a road cyclist who occasionally encounters dirt roads or slush in winter?
Some riders use SPD pedals on their road bikes during rainy seasons or in colder months. They’ll have a separate set of SPD winter boots that keep feet warm and dry, paired with pedals that handle slush better. Then, come summer, they might switch back to SPD-SL. It’s not a requirement, but it’s an option that some folks enjoy.
Comfort and Hotspots
Ever felt a burning sensation under the ball of your foot after a long ride? That’s often called a “hotspot.” While a lot of this discomfort can be related to your shoe’s insole or overall fit, pedal choice can also play a role. The bigger surface area of an SPD-SL pedal sometimes helps distribute pressure more evenly, reducing hotspots for people who like to push higher wattage or ride big mileage on pavement.
However, plenty of riders using SPD pedals say they don’t get hotspots at all, especially if they have supportive shoes. Good insoles and a well-fitted shoe can resolve many foot pain issues, regardless of pedal system.
Other Pedal Systems – A Quick Mention
Shimano isn’t the only game in town. You’ll come across Crankbrothers, Wahoo/Speedplay, Look, and Time, among others. Some of these designs are SPD-compatible, meaning you can use SPD cleats with them. Others are not. For example, Look’s three-bolt system won’t match up with Shimano SPD-SL, and Speedplay has a unique four-bolt cleat that needs an adaptor to fit three-bolt shoes.
If you find yourself gravitating toward something that’s not Shimano, just double-check that your chosen shoe is compatible, and remember that you might need different cleats if you switch pedal brands.
Tips for the 50+ Cyclist
- Comfort is Key: Sometimes, riders who’ve been at it for years don’t want to fuss with new gear. But clipless pedals can add comfort by stabilizing your foot. Just be sure to adjust the cleat position so your knees track naturally.
- Practice Clipping In and Out: Don’t wait until you’re out on a busy street. Practice on a quiet road or near a wall you can hold for balance. Repetition builds muscle memory.
- Start with Softer Tension: Nobody wants to tip over because they couldn’t disengage in time. Keep the pedal release looser at first. You can always make it tighter later.
- Check Cleat Wear: If you’re using SPD-SL cleats, keep an eye on those plastic cleats. Once they get worn or rounded, it’s time for a replacement.
- Explore Cleat Position: Shifting the cleat a little forward or backward can change how your knees feel. That small adjustment can be the difference between comfort and pain after a long ride.
Changing Pedals and Shoes
If you’re upgrading your bike or switching from one pedal type to another, it’s helpful to have the right tools. You’ll need a pedal wrench or an Allen key, depending on the pedal’s design. Grease those pedal threads before you screw in your new pedals, and tighten them securely without overtightening.
For the shoes, make sure they match the cleat system:
- SPD shoes have two-bolt holes, often arranged in a slot so you can slide the cleat forward or back.
- SPD-SL shoes have three-bolt holes in a triangular arrangement.
- Some shoes are “two-bolt only” or “three-bolt only,” while others have both patterns.
Common Myths and Misconceptions
- “Clipless pedals are dangerous.” Once you’re used to clipping in, they’re no more dangerous than riding with flat pedals. You just have to practice disengaging.
- “SPD-SL is only for pro racers.” Though pros do use them, plenty of regular folks enjoy them for everyday road cycling.
- “SPDs are only for mountain bikes.” Many road cyclists use SPDs for commuting or touring because they’re so convenient for walking.
- “I’m too old to change pedal systems.” Nonsense. Cyclists in their 60s, 70s, and beyond discover clipless pedals and never look back. Just take it one step at a time.

Final Thoughts
Here’s the thing: cycling should be fun. If you like to ride on different types of terrain and wander around off the bike, SPD pedals will probably serve you better. If you mainly stick to paved roads and prioritize a smooth, efficient pedal stroke, SPD-SL is a great friend. Some folks even keep two sets of pedals and shoes for different riding conditions—especially helpful if you’re a year-round rider tackling various surfaces and climates.
For many riders over 50, comfort, practicality, and knee health might trump everything else. If you love road rides but still like strolling around at the local rest stop without wobbling like a duck, SPD might be the sweet spot. If you’re all about dedicated, speed-focused road cycling and you rarely dismount, SPD-SL can give you that secure feel and might be your favorite companion.
Remember, there’s no absolute right or wrong choice—just whatever keeps you smiling on two wheels. Whichever path you follow, set those pedals up properly, dial in your cleat placement, and you’ll be on your way to comfortable riding. Clipless pedals can feel intimidating at first, but once you nail that clip-out maneuver, you’ll probably never want to go back.
So pick the system that fits your style, get out there, and enjoy the ride! Before long, you’ll find yourself wondering how you ever managed without that solid connection between shoe and pedal. You know what? You might even start eyeing those quiet hills in the distance, excited to experience them all over again—just with a little extra pep in your step.
