Asked by: Dashaun Hartford

Are all BMX freewheels the same size?

Freewheels are available in sizes 13T to 28T and in the same two different widths as the cogs (3/32″ and 1/8″). ACS makes a special “FAT” heavy duty BMX freewheel in 14T and 16T with 3/16″ teeth compatible only with 3/16″ chains.

What thread is a freewheel?

1.375 x 24 TPI

The standard ISO threading for freewheels is 1.375 x 24 TPI, the same as for standard ISO bottom brackets.

Are all freewheels interchangeable?

No, freewheels are completely different from the cassette / free hub system and are not interchangeable. A freewheel includes the ratchet mechanism that allows the sprockets to rotate backwards as well as the sprockets themselves, and threads into the hub.

How do I know what size freewheel I need?


Quote from video: On a bike it can be difficult to determine if you have a cassette or free will but this is the simplest way. After you remove the rear wheel from the bike spin the sprockets backwards.

What is the difference between freewheel and freehub?

The term “freewheel” refers to the whole gear cluster with the coasting mechanism inside. The freewheel is screwed onto a set of threads on the right-hand side of the wheel’s hub. On a freehub system, the coasting mechanism is a sub-assembly of the wheel’s hub.

Do all cassettes fit all hubs?

Most cassette hubs are compatible with Shimano cassette cogs. SRAM cassettes and most Miche, IRD and SunRace cassettes use the same inter-sprocket spacing as Shimano, but at least some SRAM 10-speed cassettes do not fit aluminum-body Dura-Ace hubs.

How do I know what cassette is compatible with my bike?

For a smooth ride, you need to have the right combination. For example, if your bike has a standard double 53/39 crankset, you can have slightly low gearing (12-27t) even if you ride in a hilly vicinity. But if you have a more compact crankset, say 50/34, you’ll be good having a 11-23 cassette.

Which is better Pawls or ratchet?

Ratchet systems are generally spoken stronger, more reliable and need less maintenance compared to traditional pawl systems. Biggest reason for this is that the power transferred from the drivetrain to the wheel is spread of a larger surface. In general hubs that are “louder” usually have more engagement points.

How many speeds can you get with a freewheel?

The Freewheel



It typically comes with anywhere between 1 to 7 cogs, and it is rare to find a freewheel on a modern bike. You do however find them on some new single-speed bikes. A freewheel that comes with 1 cog can also come fixed, meaning that you always have to be pedalling unless the bike is stationary.

Are 6 and 7 speed freewheels interchangeable?

6 Speed to 7 Speed



If your bike currently has a regular-spaced 6-speed freewheel, you can generally upgrade to 7-speed with little trouble. Since the sprockets are closer together on a 7-speed freewheel, the overall width is only very slightly wider than a regular-spaced 6-speed.

What is the best single speed gear ratio?

For flat places, a ratio of 2.6 to 3.0 is ideal for most people. The lower value of this range, with a cadence of 90 rpm, will allow us to ride around 30km/h, while the upper, 34km/h. If you’re just starting out on your adventure on a single speed or fixed gear bike, a gear ratio of around 2.7-2.8 will be ideal.

What’s the difference between freewheel and cassette BMX?

fyi a cassette and a freewheel are functionally identical insofar as they allow freewheeling (i.e. you can coast, but not backwards). The difference is that a cassette is splined and fits onto the freehub assembly part of a hub, while a freewheel threads onto the hub body itself.

Can you put bigger wheels on a BMX?

You can’t go larger because the wheel will hit the frame, and you usually can’t go smaller because the brakes won’t work, or the pedals will hit the ground. Tire width can be changed to a degree.

How wide should BMX tires be?

Flatland and Freestyle BMX



Buy tires about 2.125 inches wide if you’re a freestyle or flatland rider with a pro-size bike. The wider tires give you more balance and control. Ask for tires about 1.75 inches for expert freestyle frame sizes, 1.3 inches for junior and 1.1 inches wide for mini frames.

What is the difference between BMX and freestyle bikes?

Brakes: Freestyle bikes come with front and rear brakes. BMX and jump bikes usually sport only rear brakes. Brake type is also important. BMXers require pure stopping power so they prefer linear-pull brakes, which offers the ultimate grip.
