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.
What to do when rear wheel wont come out?
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. Reach down with your free hand and pull back the derailleur with your hand to get it, and the chain, out of the way.
How do you put a rear wheel back on?
Remember that you shifted the chain onto the smallest rear cog before you removed the wheel. So, you must put the wheel back on by first lining that smallest cog up just right so that the chain is on it. Also, pay attention to how the chain rests on the cog.
What happens when you remove the rear wheel on a bike?
On most bikes with rim brakes, when you try to remove the wheel, the tire bumps into the brake pads. This is because the brake needs to be adjusted close to the rim, while the fully inflated tire is significantly wider than the rim.
Is the rear rim centred on the hub?
Drum brake Commandos, like their Matchless and Featherbed framed predecessors using the same hub, have their rear rims centred on the hub.
Where is the front wheel supposed to be?
If the rear wheel is centred in the swinging arm, and the swinging arm is centred in the frame, then the front wheel should be as well. Since the steering head by definition is on the frame centre line, then the front wheel should be centred in the forks.
Which is correct front or rear wheel offset?
The offset on the front is way off, such that the tyre is contacting the fender bracket. The rear I’m pretty sure is OK, since the tyre is equidistant between the swinging arm – it’s not positioned in the middle of the fender, but that might be correct ”
