How do I know what size axle I need?
For a front thru-axle, this is measured from the inside to the inside of your fork. For a rear thru-axle, this is measured from the inside to the inside of your frame at the drop-outs. The O.L.D. measurement is often listed for many thru-axles but isn’t necessary if you know the overall length.
Are thru axles interchangeable?
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 is a 15mm 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.
What size is a bicycle axle?
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 is standard thru axle size?
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 you measure an axle axle?

Can I convert quick release 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.

This is where PDXTI’s carbon 12mm to 15mm thru-axle adapter comes in handy. Weighing a paltry 9.7 grams, this simple tube of carbon fiber slides into your wheel’s 15mm front axle, spacing out the front axle and allowing you to utilize a 15mm thru-axle front wheel on a fork designed for 12mm.
Can you use 12mm thru axle on 15mm hub?
Some 12mm thru axle forks are only compatible with hubs which have end cones with a maximum outer diameter of 19mm. If ‘A’ is less than 4.5mm you can only use a hub that has a maximum outer diameter end cone size of 19mm. …
