If DIY no documentation available: Measure the hole diameter on the crank arm (at the inner side, opposite to the pedal) or take one of the original pedals off your bike and measure the threaded part, you’ll need a caliper for that.
What size pedals do I need for my bike?
- Luckily, the majority of all pedals come with a 9/16” thread size with 20 threads per inch. Pretty much all modern adult bikes have this type of thread. Therefore, changing pedals will usually not be a problem. Pedals with a ½” inch thread can be found only in BMX bikes, kids bikes, and in some cruiser bikes.

How do I know my bike pedal size?
Manufacturers have made it nice and easy for this one, and all you have to do is check the cranks on the bike. If your cranks are made up of three separate sections, two separate crank arms and the spindle that goes through the frame then your pedals will be size 9/16” x 20 tpi.
What is the standard bike pedal size?
Bicycle pedals are commonly a 9/16″ x 20 threads per inch. The inside diameter of the internal thread (the “nut”) must be smaller. Measured in millimeters, the OD of the pedal is typically 14.2mm.
Do bike pedals have different sizes?
When it comes to pedal sizes, there are two sizes: ½” and 9/16”. ½” pedals are only used on very basic bikes with a one piece crank. A one piece crank is just that, it’s one piece of steel that is bent/forged to run from one pedal, through the frame, to the other pedal.
How do you measure pedal width?
Stance Width (or pedal stance width) is the distance between the center of one pedal to the center of the other pedal.
How are pedals measured?
The overall size of each of our pedal designs slightly changes where your feet should rest on them. The way it’s measured is from the middle of the pedal to the crank arm. Once you’ve found the right-sized flat pedal for you, you might be interested in exploring your different pin options.
Are all pedals 15mm?
The flats on almost all modern pedals take a 15mm spanner, though many pedal spanners also have a 9/16-inch jaw for older pedals.
How do you tell if my pedals are 1 2 or 9 16?
If the cranks are THREE PIECES, meaning two crank arms bolted to a spindle, it will be 9/16 thread on the pedals. If the crank is ONE piece through a large bottom bracket housing, it’s 1/2 thread.
Are pedal sizes universal?
Bicycle pedals are not universal. In fact, there are two main bicycle pedal sizes: 9/16” and ½”. The 9/16” bicycle pedals are used very often and are the standard in pedals, while the 1/2” pedal and other variations of the bike pedal are used less often.
Are pedals standard?
There are two major pedal standards depending on spindle mounting thread diameter. The other is standard MTB and road bike pedal, with 9/16″ thick spindle. Both standards have 20 tpi (threads per inch). If a bicycle is not a kids bicycle, then there’s 99% chance it has 9/16″ pedals.
Are bike pedal arms universal?
Pedals are universal as long as the thread is the right size for the crank that you have on your bike. The 9/16 20 TPI size is pretty much standardised on adult bikes in the industry now, meaning there are just the two main threads as previously mentioned.
Are clip in pedals universal?
When you purchase clipless/clip-in pedals, the cleats designed to be used with those pedals are included in the box. Clipless/clip-in pedal cleats are specific to the manufacturer; so, for example, Shimano cleats are not compatible with Look pedals.
Are all flat pedals universal?
Yes, pedals are universal for mountain bikes. But this depends on the type of crankset you have. A 1-piece crankset uses 1/2′ inch in diameter pedals. Two piece and three piece cranksets use a 9/16′ inch in diameter pedals.
Do I need wider pedals?
Longer pedal spindles might be recommended. This rider’s stance width is too wide; the knees are tracking to the inside of the pedals. Shorter pedal spindles might be recommended. Proper stance width keeps knees happy and power transfer efficient, no matter the clipless or platform pedal you’re spinning.
Do I need pedal extenders?
If physiological issues are causing pedaling discomfort, a pair of bike pedal extenders is probably the solution you need. If you are looking for performance enhancement, pedal extenders will not be the first thing on your list.
How do you measure pedal spindles?
Speedplay’s spindle lengths are measured from the pedal shoulder—where q factor leaves off—to the center of the pedal platform. This is handy, if you want to measure the absolute width from one pedal platform to the other.
