There is a lot on the market with regards to bike pedals and cranks, therefore hopefully with this guide you can narrow down the size of pedal that will fit your bicycle.<\/p>\n\n\n\n

Are All Bike Pedals the Same Size?<\/h2>\n\n\n\n

Bike pedals are not all the same size. Bike pedal sizes vary due to the crank arms dictating the specific sized threads that it will take; this is mainly dependent on the age of the bike as well as the type of bike that you have.<\/p>\n\n\n\n

For example vintage bikes with a one piece crankset will often take a different size pedal thread in comparison to a modern bike from a big manufacturer.<\/p>\n\n\n

Are All Bike Pedal Threads the Same Size?<\/h2>\n\n\n\n

No bike pedal threads are not the same size. These days there are two major sizes. For example, 9\/16 20 TPI (threads per inch) is the most common size of thread used on bicycle pedals<\/a> and will be the size needed for all modern bikes today. <\/p>\n\n\n\n

The other size thread that is used, but is less common, is \u00bd 20 TPI which is used mainly for childrens bikes and BMX bikes. There is also an old style French thread that is far less common which measured in at 0.55 20.32 TPI (14 mm x 1.25 mm).<\/p>\n\n\n\n

So… Are Bike Pedals Universal?<\/h2>\n\n\n\n

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. <\/p>\n\n\n\n

Therefore you can relax knowing that when you buy a modern style bike, whether it\u2019s a mountain bike, hybrid or a road bike, you will find that it takes a 9\/16 20 TPI thread pedal. <\/p>\n\n\n\n
