How do I know what size thru axle I need?

For this reason, thru-axles should be measured by overall length. Depending on the thickness of the dropouts, total length is usually 20-30mm longer than OLD. The most common front thru axle OLD dimensions are 100 mm, 110 mm, and 150 mm for front axles and 130mm, 135mm, 142mm, 148mm, and 197mm for rear axles.

Are thru axles better than quick-release?

1. Thru axles are safer– This is probably the biggest benefit for the average cyclist. Thru axles improve safety by making it nearly impossible for the front wheel to come out of the dropouts while you’re moving. The dropouts can’t lift off of the axles vertically because they have holes instead of a u-shaped slots.

What is standard thru axle size?

Front thru-axle standards



The standard size for thru-axle forks on mountain bikes used to be 15mm x 100mm, with 20mm x 110mm used mainly on downhill and freeride bikes. For trail, XC and enduro bikes that’s largely changed to the newer Boost thru-axle standard, which increases the front axle length to 110mm.

Diameter: the skewer must fit inside the hollow hub axle. You may measure either the inside diameter of the axle, or the diameter of the present skewer. Most axles use a 5mm thick skewer. Skewers for wheels made for suspension forks may be 9mm (front) and 10mm (rear) in diameter.

What does 12×142 mean?

12 mm is the axle diameter, 142 mm refers to overall shoulder to shoulder width of hub (end cap to end cap) Cassette and disc rotor are in the exact same relation to the hub’s centerline as a standard 135 mm QR hub.

How do you fit through axles?

Quote from video: If you need to change the finished position of the lever. You can adjust the axle net if the axle nut has a retention cap use a small allen wrench to remove the screw and plate.

What happens if you over tighten thru axle?

Keeping the axle under-torqued is dangerous, and over-torquing it might damage the fork/frame dropouts. A proper solution would be to adjust the position of the brake caliper itself relative to the disc.

How important is rear thru axle?

Thru-axles increase the rigidity of the wheel-frame interface and allow more accurate wheel placement. This is particularly important for brake discs, where small pad clearances mean that a slight misalignment will cause rubbing. They also eliminate the risk of the wheel coming loose from the quick-release dropouts.
