Because thru axles are a relatively new development invention, there is currently no industry standard.
Countless different manufacturers produce their thru-axles to different specifications, making it impossible for Tailfin to make a single thru axle that will suit every bike
.
What size thru axle do I have?
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
.
How do I put an axle on my rim?
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 a 12mm thru axle?
From this specification we know 142mm is the hub width (or frame spacing) and 12mm is
the diameter of the axle
. We need to specify the following items to get the proper replacement Thru Axle.
Are thru axles universal?
The new
Universal Thru-Axle
takes the guesswork out of choosing your axle and also future proofs you in case you swap bikes or indeed have different bikes with differing axles.
How do I replace an axle?
How do I know if my bike has a thru axle?
Thru Axles
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 do you make a simple axle?
How do you fit a stub axle?
Take the stub axles and a sample of the axle tube to your local machine shop and get them to machine the welds down to enable a nice snug fit within the axle tube. Once machined, dry fit the hubs (with the cheap bearings), slide the stub axles into the axle tube up the 25mm mark and tack weld into position.
How do you put PVC wheels on?
Does a bike have an axle?
Quick release axles are the standard wheel attachment system used on most bikes
. They allow you to remove and replace the wheels quickly and without any tools. You don’t even need to remove the axle from the hub.
Can you change QR to thru axle?
some manufacturers offer frames have removable rear dropouts that can be swapped for through-axle
, quick release other style dropouts. With some forks it is possible and cheaper (but never cheap) to replace just the lowers.
How do I know if I have a differential axle?
How do you tell if you have a full floating axle?
You can spot a full-float rear axle by looking at the wheels.
Full-float axles have a tell-tale “axle end” that sticks out from the wheel surface
. This is because the wheel hub on a full-float 14-bolt axle will stick out beyond the wheel mounting surface anywhere from about two to four inches.
How do I know my rear axle ratio?
Turn the wheel TWO revolutions and count the number of driveshaft turns
. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.
Do you grease through axles?
Although it is not required, it is recommended that you apply a light amount of grease to your Mountain Bike axles
. You can apply it to the threads, and also on the base of the axles themselves. This not only makes them easier to install and remove, it also helps prevent rust and corrosion.
What does old stand for bike?
The hub spacing is measured from the outside face of the lock nuts (or equivalent), this is commonly called the “O.L.D.” (
Over-Lock-nut Dimension
)
Which is better quick release or thru axle?
With a thicker axle bolted directly onto the bike, strength and stability are greatly improved. The end result is a stiffer front end and the elimination of brake rub. Plus, by adding a camming mechanism (like the QR lever) you can still remove your wheel quickly.
Thru axles are safer and improve bike performance
.
Can you convert thru axle to quick release?
Convert your existing 15mm Thru Axle Hub to a standard 5mm Quick Release Skewer to fit standard dropout 9mm x 100mm forks
. No tools required for installation. Simply insert the Adapter into the thru axle hub and secure the wheel using a standard 5mm quick release skewer.
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.
How do you install a rear axle?
How do you fit a bike axle?
What is a bicycle axle?
A bike axle is
a component on a bicycle that allows the wheel’s hub to rotate
. It is generally a solid piece of metal which is round and threaded. The threads allow axle bolts and bearing crown races to be secured in place.
What is a bicycle through axle?
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.
