How do I know what size rear hub I need?
How do I know what size rear hub I need?
If you are unsure of your frame spacing or have an older bicycle, measure the hub width to ensure a proper fit. To do this, remove the rear wheel and use a pair of calipers or a ruler to measure the distance between the inner surfaces of the dropouts.
Do rear hubs make a difference?
Hubs that are “louder” usually have more engagement points. This means your drivetrain picks up faster, so less energy is lost. Hubs that have sealed cartridge bearings or needle bearings usually never need to be replaced, they’re far stronger and stay cleaner.
Do bike hubs have sizes?
Choosing a hub Hubs are generally 100mm wide in front and 130mm wide in the rear for road bike frames; mountain bikers generally use 135-142mm front and rear hubs to allow space for disc brakes, which require extra material on the outer edge of the hub for mounting the disc.
What hub will fit my bike?
Hub spacing is simply the width of the hub of the wheel, as it fits into the frame or fork….Common Bike Hub Spacing Standards.
| Hub Spacing | Front Hub Spacing | Rear Hub Spacing |
|---|---|---|
| Road Spacing | 100mm | 130mm |
| Regular MTB Spacing | 100mm | 142mm |
| Boost MTB Spacing | 110mm | 148mm |
How do I measure my hub size?
Place a tape measure across the face of the exposed wheel hub, which it protrudes out from the center of the drum brake assembly. Take the measurement across the front of the hub, which is the diameter of the hub. Make sure your tape measure intersects the center of the hub. Write your measurement down.
Why are Chris King hubs so loud?
This noise is usually caused by the pawls on the hubs making contact with the engagement surfaces, which are part of the ratcheting unit. This contact makes noise because high-end hubs have more pawls and more engaging units than cheaper hubs. So more pawls are hitting the engagement points to create audible sounds.
How do you count holes in a hub?
Hole Count – Your hubs and rims should match each other’s hole count….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.
Are all bike hubs the same size?
For the vast majority of bikes, that is where we are now for axle and hub standards. Most road, CX, and gravel bikes come with 12X100mm thru axle front and 12X142mm thru axle rear. Most mountain bikes come with 15X110mm thru axle front and 12X148mm thru axle rear.
