Single Speed/Fixie Wheels with cup and cone bearings

6 min read

Asked by: Shawn Rike

How tight are cone and cup bearings?

Quote from video: Exactly this is likely to be somewhere between 30 millimeters and 16 millimeters hold the axle still with an axle vise and turn the lock nut anti-clockwise to unlock the bearing.

What is a cone and cup bearing?

A bearing system which consists of a cup contains balls adjusted by a cone nut. This system features high durability and good maintainability. The key element of maintenance is to keep smooth rotation yet without a play.

Is a fixie single-speed hard to ride?

Fixies are pretty, tough and super low maintenance



Fixies are perfect for riders who hate looking after their bikes. You still need to lube your chain occasionally, but there are no gear cables and derailleurs to get gunked up or go out of adjustment, and there’s no vulnerable hanger to get bent at the bike racks.

What is the difference between single-speed and fixie?

So what is the difference? Single speed bikes are fitted with a freewheel, whereas fixed gear bikes are not. On a fixie the rear cog is joined with the rear hub, so when the wheel turns, the cog will turn too.

How can I make my bike spin faster?

Quote from video: And what you're going to do is continue to do this another little trick is is you can use the you can use the spray cleaner and the propellant to make the bearings spin the grease out itself like.

How do you adjust cup and cone bearings?

Tighten adjustment:

  1. Use a cone wrench and hold cone from moving. Note position and angle of wrench.
  2. Use another wrench on locknut and loosen by turning counter-clockwise.
  3. Recall angle of cone wrench and tighten adjustment by turning cone clockwise 1/32nd of a turn. Imagine cone wrench extending to the rim.


Is a bearing cup the same as a bearing race?

The parts of a bearing



The outer race, or cup, is the bearing’s exterior ring. Since it protects the bearing’s internal parts, it must be machined smoothly and accurately. The inner race, or cone, is the part of the bearing that sits directly on the shaft.

Is Shimano hub sealed bearing?

They are both sealed. High grade shimano hubs are actually pretty well sealed.

How tight should a bike wheel be?

It should be tight enough that it requires some force to get it closed, but not so much that you feel like you’re giving birth. The closed QR lever should come be positioned before or after the fork in the front and between the chain stay and seat stay of the rear triangle, or just below the chain stay.

Why do hipsters ride fixies?

On a Fixie it’s not unheard of to get a real ‘feeling’ for the road. Hipsters feet are always connected to the vibe of what’s going on around them; in this case, to the pedals and the motion of the bike.

Why is my fixie so slow?

Something (like, say, the brakes, if your fixie has them) might be dragging against the wheel(s), slowing you down and making you work hard to keep going. Or, just possibly, there might be something wrong with your wheel bearings, causing the same effect.

Is fixie good for uphill?

Is it hard to ride a fixie uphill? Yes, it can be hard to ride a fixie uphill. A fixie is a bicycle with no gears, so you must pedal with your feet to move forward. This can be a little bit tricky when you’re trying to ride up a steep climb since your bike will weigh a lot more than when you are riding it downhill.

Will a lighter bike make me faster?

Bottom line: A lighter bike may save you a few seconds per climb. But if you really want to get faster, there are better ways to spend your energy and money, like shedding bodyweight, upgrading your wheels, and making your bike more aerodynamic.

Do hubs make your bike faster?

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.

Why does my bike feel slow?

Slightly flat tires are the most common reason your bike feels slow. Rolling resistance increases dramatically when pressure is too low for your weight. Note that even if your tires don’t look flat, they might still be far softer than is ideal.

How tight should bearings be?

For context, the tolerable end-play for truck wheel bearings is the same: 0.001 to 0.005 inches, also expressed as 1 to 5 mil or 0.025 to 0.127 mm. In other words, it’s perfectly acceptable to adjust wheel bearings so that they are just a little bit loose, but not too loose.

How tight should hub cone?

If you adjust the cones so that they feel just right off the bike, they will bind up when you tighten the quick release. You must set the cones so that there is a little bit of play when the hub is off the bike, or when the wheel is installed with the quick release just barely tightened.

How tight should hubs be?

The hub should spin freely, with a bit of brake lining drag. There should be a little bit of end play (wobble), but not much. At this point, o make sure the hub is seated properly, back off the castle nut until it is loose. Then tighten the castle nut snugly until it stops.

How tight should a bike hub be?

You want your rear axle very tight. 150 in/lb is about standard. If it is not tight it will allow the rear wheel to move around and it ties your rear triangle together. Basically the whole back of the bike will feel sloppy.

Can a quick release be too tight?

Unless you’re unusually weak, not being able to open it means it is on too tight. Even if you are somewhat weak, unless you have disk brakes “as tight as you can” should be ok. Note that if you have disk brakes it is much more important that the quick release be tight.

Should I grease through axle?

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.
