Cycling pedals come in three main types: flat pedals, clipless pedals, and toe clips, with the choice hinging on your riding style and comfort.
For new cyclists, the range of pedal options can feel overwhelming. “Clipless” pedals require special cleats on your shoes, while flat pedals let you ride in sneakers. Your choice of cycling pedals more or less pins down how you’ll ride, what shoes you’ll need, and how you’ll handle a quick stop. This article breaks down the three types of cycling pedals so you can pick the right one for your riding.
What Are The Three Main Types Of Cycling Pedals?
Every pedal on the market falls into one of three camps: flat, clipless, or toe-clip. The one that suits you comes down to your comfort and the kind of riding you do.
Here’s the breakdown:
- Flat pedals are the simplest—a large platform you push against with a regular shoe. Shimano’s pedal lineup chart groups these as especially suited for downhill and gravity riding, plus casual riders who spend as much time off the bike as on it.
- Clipless pedals are named for the absence of old toe clips and straps, even though the rider “clips in” to a cleat-equipped pedal. They lock your shoe to the pedal for better power transfer.
- Toe clips and straps are older technology, a basket and strap that holds your foot on a flat pedal. Shimano notes these are now largely considered outdated compared with clipless systems.
Clipless Pedals: What Are The SPD And SPD-SL Standards?
Shimano calls its clipless systems SPD and SPD-SL, and they are not compatible because they use different cleat and pedal standards.
Shimano describes SPD as a 2-hole system preferred for off-road, cyclocross, and casual riders because it is easier to walk in and provides more float. SPD-SL is a 3-hole system popular with road cyclists because it offers a larger platform and better power transfer for steep climbing and long-distance riding. Road systems like SPD-SL and Look’s Keo use 3-bolt cleats; gravel and MTB systems use 2-bolt cleats for walkability and mud clearance.
The cleat standard dictates your shoes. Two-bolt cleats are recessed into the sole, making them easier to walk in. Three-bolt road cleats protrude more, so they’re worse for walking. If you plan to walk around much, a recessed 2-bolt system is the choice.
Cleat Float: Road System Options
Look and Shimano give road cleats a set amount of “float” so your foot can rotate slightly while clipped in, easing knee strain.
How To Choose Between Flat, SPD, And SPD-SL
Shimano’s official lineup implies a simple rule: choose SPD for off-road, commuting, and walkability, SPD-SL for road performance, and flats for downhill or casual use. For a first-time rider, flat pedals are the safest default because they allow an immediate bail-out when you need to put a foot down.
A quick breakdown of the systems:
| System | Bolt Pattern | Best For |
|---|---|---|
| Flat | None | Beginners, downhill, casual street riding |
| SPD | 2-bolt | MTB, gravel, commuting with walking |
| SPD-SL | 3-bolt | Road, climbing, long-distance performance |
| Look Keo | 3-bolt | Road racing and sportive use |
| Wahoo Speedplay | 4-bolt with adapters | Road riders wanting dual-side entry |

Do All Clipless Pedals Fit Together?
In short: no, they don’t. BikeRadar’s road pedal guide clarifies that Look’s three-bolt road cleats are not compatible with Shimano SPD-SL, so the shoe and cleat must match the pedal system from the same manufacturer. The main exception is Speedplay, which uses a different mounting pattern and a dual-entry mechanism that lets you clip in from either side.
Make sure the cleat on your shoe matches the pedal. A 2-bolt shoe only works with an SPD-style pedal, not a 3-bolt road pedal, and vice versa. Reaching for the highest-tension cleats isn’t always wise for beginners; start with the easiest release option to build confidence before heading out on open roads.
