How do I know what thread size my pedals are?
Check the Cranks on the Bike
Manufacturers made it easy to put the sizing on the crank, knowing that people would look for their pedal size. If your cranks are made up of three separate sections, two separate crank arms, and the spindle that goes through the frame, your pedals will be size 9/16″ x 20 TPI.
Are my pedals 9/16 or 1 2?
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 all bicycle pedals the same thread?
Are All Bike Pedal Threads the Same Size? 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 and will be the size needed for all modern bikes today.
Are most bike 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.
Are all bicycle pedals the same size?
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.
Why do pedals have different threads?
I read the question and your response regarding why left and right pedal threads are the opposite of what one might, at first glance, expect. The reason for this is due to the effects of precession, where one round object rolling inside another will turn in the opposite direction due to the clearance between the two.
Are all bike pedals compatible?
To simply answer: No, bike pedals are not universal. Not only visually or for their different purposes for various cycling disciplines, but also internally. Bicycle pedals mainly have two sizes: 9/16” and ½”. The 9/16” is the more standard version of pedals and covers almost all subtypes.
Are bike pedals reverse thread?
Remember, the left pedal spindle is reverse threaded. Turn it clockwise to remove the pedal when facing the crank arm. The right side is normal, so turn it anti-clockwise to loosen it.
Do bike pedals have bearings?
Bearings are found in your hubs, bottom bracket, headset, suspension pivots, pedals, shifters… the list goes on – basically, anything that moves on your bike will have some kind of bearing in it.
Is 9/16 The same as 15mm?
14mm = almost 9/16 inch. 15mm = almost 19/32 inch. 16mm = 5/8 inch. 17mm = almost 11/16 inch.
Do you really need a pedal wrench?
Most pedals (like our reliable Thump flat pedals) require a pedal wrench, which is a long, thin tool specifically designed to fit the external spindle flats between the pedal and the crank leg (fig. 3).
Are all pedal wrenches the same size?
Pedal wrench flats are typically 15mm in size. 9/16″ (~14.3mm) is somewhat common on older pedals. 17mm and other sizes have been used, but you aren’t very likely to encounter them. (A “cone wrench” is thinner and shorter than a pedal wrench, and unable to provide appropriate durability or leverage for use on pedals.
