What is the plastic thing on the rear bike wheel?
spoke protector
Commonly referred to by mountain bikers as a “dork disc”, the spoke protector is designed to minimize the chance of the rear derailleur being able to move past the lowest gear and cause damage to the rear wheel, and/or the resulting loss of control of the bike.
Is A Dork disc necessary?
They are not necessary though on a properly built/adjusted bike.
Can a rear wheel be removed from a bicycle?
Anyone can remove and install a rear wheel and it won’t affect shifting or the chain. Here’s how: This creates slack in the chain, which makes wheel removal much easier. If you’re riding, shift as you slow to a stop so that the chain is on the smallest rear cog and the smallest chainring in front.
Is it possible to repair a damaged rim on a bicycle?
And it is possible to transfer spokes from a damaged rim to a new one, making for a quicker repair. Practice in building new wheels helps build the technique to repair damaged ones. Of all the maintenance and repair jobs that may be needed on a bicycle, the trickiest is truing (straightening) wheels.
What happens when you put a rim brake on a bicycle?
A rim brake will catch on the spread-out part of the rim. This will cause dangerously uneven braking, and possibly may even cause the wheel to lock up under hard braking. It also will cause a bald spot on the part of your tire tread that is in contact with the road when the blip reaches the brake.
Can a rear wheel be used in front of a front wheel?
However, some bikes are designed for running rear hubs in the front (Surly Moonlander/Pugsley, for example). A non-Fat Bike case is the Salsa Enabler. Ignoring the dropout width and axle size, absolutely. The rear wheel supports far more weight than front wheels, so using a rear wheel up front will be perfectly fine, albeit funny looking.
Can you put a rear wheel back on a bicycle?
Think you’ll never get the rear wheel back on right? We have good news: Anyone can remove and install a rear wheel and it won’t affect the shifting or the chain. And if you work carefully, you won’t have to touch that greasy drivetrain either. Here’s how it’s done on any bicycle with derailleurs]
How to overhaul the hub of a rear bike wheel?
I show how to overhaul the hub on a rear bike wheel (disassemble, clean, lubricate, and reassemble). Overhauling the the front wheel is pretty much the same, but simpler as you don’t have to mess with the freewheel or spacers. There were nine 1/4 inch ball bearings on each side which is the most common for a rear wheel.
Why are rear wheels so easy to install?
Shifting the chain down onto the smallest cog on the rear wheel and the smallest chainring on the crankset, creates slack in the chain, which makes rear wheel removal much easier. It also makes wheel installation easier because it gives you an accurate way to line up the wheel (on the smallest cog) so that it slips right into the bicycle frame.
Why is my rear wheel not coming out?
Don’t force anything though. If the wheel doesn’t come out right away, it’s because the derailleur and chain are blocking it. To get them out of the way, keep holding the rear end of your bike off the ground by lifting the bike by the seat.
