What Is A Thru Axle Bike? (Solution found)

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.

What is the difference between quick release and thru axle?

Thru axles attach the wheels more securely and reduce the likelihood of wheel attachment caused by human error. Quick release axles allow for more flex in the front end of the bike, which hurts handling- Disc brakes can cause the fork arms to flex.

Do road bikes use thru axles?

The first crop of road bikes with thru- axles used the 15mm diameter front axles common on mountain bikes but usually retained the rear quick-release. Then in the last couple of years, rear thru-axles started to appear on road bikes; usually 12x135mm, although 12x142mm is now more common.

What is thru axle and quick release?

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.

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.

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.

Can you convert QR to 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.

Are all thru axles compatible?

How does a bicycle thru axle work?

In a thru-axle system, the dropouts have closed-off circular openings, rather than an open end. That means there’s no risk of the wheel falling out as you ride. The thru-axle passes through the dropout on one side of the wheel and screws into threads in the dropout on the other side.

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.
