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.
Do all bikes have thru axles?
The QR was never originally designed or engineered to handle powerful hydraulic disc brakes or suspension systems. This means going forward, all MTB and road bikes will come standard with thru-axles.
How do I know what axle My bike has?
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.
Do all disc brake bikes have thru axles?
If you have disc brakes you will most likely have thru axle skewers. If you have a disc brake older than 2019, you may have a quick release skewer, but disc brake road bikes made today are generally thru axle. Gravel bikes are pretty much using thru axle as the standard these days.
Do I need thru axles?
YES. Thru axles provide a stiffer ride, which can be beneficial in both the front and rear of a bike. In mountain bikes in particular, this allows for more torque and less flex for your whip. So, if you have a thin, 5mm rod, then you have a skewer.
What kind of axle do I have?
Stamped Number on the Axle
To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck.
What is the difference between quick release and thru axle?
With a thru axle system, the entire axle goes – you guessed it – straight through the fork or frame, and the axle would have to come out before the wheel to bike connection was lost. … On a quick release hub, the knurls on the end cap faces bite into the frame or fork to make a secure connection with the hub.
What is a 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. … Total Thru Axle length from the seat to the end of the threads.
Can I use quick release to thru axle?
Many hubs, like those from crankbrothers include different end caps to run with thru axle or quick release axles. … 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.
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.
Can you replace quick release to thru axle?
Converting A Quick Release Bike to Thru Axles
The best and easiest solution is to swap out your quick release fork for a thru axle fork. In most cases, you will also need a new front hub that is compatible with thru axles. 15 mm is the most common diameter for front thru axles.
Are all through axles the same?
Why are there different sizes? As with many things in the cycling industry, thru axles are not standardized. Your thru axle standard will depend on your bike’s manufacturer and your bike’s intended use.
Do road bikes have thru axles?
At the front, road bike thru-axles are now pretty much standardised at 100mm long by 12mm wide (although some early thru-axle road bikes had 15mm diameter thru-axles). Rear thru-axles usually measure 142mm long and have a 12mm diameter, but you used to be able to find a few bikes with 135mm thru-axles.
What are the advantages of thru axles on bikes?
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.
