What is thru axle fork?

How are fork axles measured?

Fork Length (Axle-to-Crown)

The more common method of specifying fork length on modern bikes, measured in a direct line from the fork crown to the axle. Length-on-Axis is the less common method of specifying fork length on modern bikes, measured from the fork crown to the axle along the steering/head tube axis.

Are thru axles better?

Compared with open dropouts and quick-release skewers, thru-axles are generally stiffer, safer and more precise. This translates to noticeably more predictable handling – even with rigid forks and hardtails – fewer accidents related to misuse, and more consistent wheel placement in the frame and fork.

What are fork stanchions?

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.

How do I know if I have a thru 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.

How important is 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.

How do I know what size axle I need?

The Distance In-Between Your Frame or Fork

For a front thru-axle, this is measured from the inside to inside of your fork. For a rear thru-axle, this is measured from the inside to inside of your frame at the drop-outs. The O.L.D.

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.

What axle do I have?
