How do I know my bikes axle size?

The Overall Length measurement. The best way to know what to get is to measure the axle you are replacing. The overall length is measured from the base of the head to the tip of the threads. If you can’t measure your existing thru-axle, try checking with the manufacturer to see if they list the spec.

What size is a bicycle axle?

Some axles have integrated cam levers that compress axle elements against the fork leg to lock it in place, while others rely on pinch bolts on the fork leg to secure it. Diameters for front thru axles include 20 mm, 15 mm, 12 mm, and 9 mm. Rear axles typically have diameters of 10 or 12 mm.

What is 15mm thru-axle?

15mm thru axle uses a different connection on the fork where the axle of the wheel allows a 15mm bolt to go through it. Same concept for a 20mm thru axle. Some wheel manufacturers have adapters that allow you to use the same wheel with the different fork hub standards by swapping out the axle ends.

Can you convert thru axle to quick release?

Convert your existing 15mm Thru Axle Hub to a standard 5mm Quick Release Skewer to fit standard dropout 9mm x 100mm forks. No tools required for installation. Simply insert the Adapter into the thru axle hub and secure the wheel using a standard 5mm quick release skewer.

Is my bike through axle?

Your bike has a thru axle if the “drop out” is a hole, rather than a U-shaped dropout. This provides added security because even if the lever on the end of the thru axle flips open, it is still threaded into the frame, holding your wheel on. If you have a 12mm threaded piece, then you have a thru axle.

Are bicycle axles the same size?

Axle length is not the same as hub length. A bike with a 12×142 hub standard will have a significantly longer axle since it will have to go through the frame on both sides of the 142mm wide hub.

What are the different types of bike axles?

There are two types of Axles; Quick Release and Thru-axles (which come as standard or boost).

What is a through axle on a bicycle?

A thru-axle (TA) is a wheel attachment system that secures a wheel on a hub between a pair of dropouts on a bicycle frame or fork. The thru-axle threads directly through the fork/frame holes and into the wheel hub, which makes the wheel secure from detaching.

Can you convert 15mm thru axle to 12mm?

Some 12mm thru axle forks are only compatible with hubs which have end cones with a maximum outer diameter of 19mm. Several thru axle hubs have end cone outer diameters larger than 19mm (typically 21mm) and will not fit into the recessed area under the hub location lip.

Do I need thru axle adapter?

You’ll need an adaptor in order to fit a thru axle bike to a wheel-on trainer. You usually have to buy the adaptor separately. Most direct drive trainers now come with whatever’s necessary to use it with a thru axle bike.

Can I convert 12mm thru axle to quick release?

This product converts 12mm thru-axle hub to standard 9mm quick release. Tool-free installation, just insert the adapter into the thru axle hub. Both sides of the product are provided with a rubber ring, which is not easy to be shaken after installation.

What is the difference between quick release and thru axle?

Both quick release skewers and thru axles are metal rods that keep bicycle wheels in place. Skewers use a camming mechanism to secure the wheel to u-shaped fork dropouts. Thru axles thread through the wheel hub and circular dropout holes. Thru axles work better to keep wheels attached to the bike.

Can I fit thru axle to QR?

If you’re fortunate enough to have a newer hub though, it’s simply a matter of popping off the QR end caps and installing the correct thru axle end caps for the fork you’re using. This adapter from Problem Solvers will allow you to mount a 12mm thru axle hub in a QR fork, but not the other way around.
