Skewers for wheels made for suspension forks may be 9mm (front) and 10mm (rear) in diameter. Skewers for seatposts and stems are commonly 6mm in diameter. Do not use an undersize skewer.
Hub Flange Diameter - The distance across the hub's flange from hole to hole.
Here's how to measure these distances:
- Figure out the distance between the lock nuts (where the hub sits in the dropouts) - 100 or 110 mm is typical for the front.
- Take that number and divide by 2.
- Then measure from the flange to the lock nut.
COMPATIBILITY – This skewer is universally compatible with most bike trainers. But for best fit and compatibility, use it with Alpcour bike trainer stands. Fits with rear axels with a diameter of 4.92â€-6.57â€.
Your bike has a thru axle if the “drop out†is a hole, rather than a U-shaped dropout. 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. If you have a 12mm threaded piece, then you have a thru axle.
A quick release skewer is a mechanism for attaching a wheel to a bicycle. Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing the cam lever, thus more quickly than wheels with solid axles and nuts.
springs are not needed for skewers. They do one thing, and that is makes it easier to put the wheel on the bike by centering the skewer. It also helps with changing wheels quickly during a race.
Ti skewers will make your bike and your wallet lighter. Ti = really expensive = really light = usually racing parts = shortened lifespan due to the gram saving which actually weakens the parts for the long haul. If you race and need every ounce shaved off and your sponser is paying then they're great.
A quick release wheel has a hollow axle, 9mm in diameter at the front and 10mm at the rear, with a 5mm diameter skewer that passes through it.
In order to change the axles in your front wheel, you need to get the right quick-release axle set for the hub on your wheel. Since hubs vary a lot, the best way to do this is to visit a bicycle shop with your wheel and tell them what you want to do. Then you can install the new quick release-compatible axle set.
Drop the wheels out of the frame and check the hub grease. The axle should not be sticky to turn, indicating dried up grease. For quick-release skewers, while it is out of the bike, put a drop of lubricant in the quick-release cam and work it back and forth.
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.
The 9mm qr system is when the axle is part of the hub assembly & the axle has a hole through the middle of it were a quick release skewer goes through to clamp the wheel to the bike. With a through axle the axle is not part of the hub assembly,The hub setup has a hole through the centre that the axle pushes through.
Inspecting Your Quick ReleaseIf it reads "open," the wheel can come off!! There are two ways to tell if the lever is open: most levers are marked "open" (photo) and "closed" so look for these markings. When the bend protrudes outward like a bump, the lever is closed. When the bend is cupped, the lever is open.
