Does my bike 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. … If you have a 12mm threaded piece, then you have a thru axle.
Is a thru axle quick release?
The rise of through-axle systems
TA typically thread into the frame or fork tip and have a quick-release lever to assist with tensioning the axle.
What is a bike thru axle?
What is a thru-axle on a mountain bike? 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.
How do I know what size axle I need for my bike?
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. measurement is listed for many thru-axles, but isn’t necessary if you know the overall length.
Are thru axles worth it?
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.
Are quick release wheels safe?
Know Your Quick Release
Incorrect quick-release use is dangerous because these mechanisms hold the wheels in place. The most common mistake is simply turning the lever like a nut until the wheel seems tight. Used this way the lever and wheel can loosen as you ride leading to catastrophe.
Can I replace QR with thru axle?
You can use through bolts (which can be quick release) in QR dropouts. These require specific hubs that allow for a 9mm front through bolt and a 10mm rear through bolt. On most Shimano hubs (and some similar Formula type hubs) you can replace QR axles with solid axles and use axle nuts on each end.
What is 12mm thru axle?
Example of how to measure Thru Axle specifications.
From this specification we know 142mm is the hub width (or frame spacing) and 12mm is the diameter of the axle.
Is quick release bad?
Incorrect quick-release use is dangerous because these mechanisms hold the wheels in place. The most common mistake is simply turning the lever like a wing nut until the wheel seems tight. Used this way the lever and wheel can loosen as you ride and can come off unexpectedly.
Is thru axle better than QR?
The solid through axle will be much stronger than your old QR axle.
What is the advantage of a 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.
Are bike axles universal?
Generally speaking, the answer is no. Not all skewers are compatible with all quick release wheels. There are different diameters and widths of skewers. Notably, many downhill bikes have beefier skewers that are built with a much larger diameter to be more durable.
