Is this brake mounted incorrectly?

The brake pads are too high and barely contacting the rotor, which is wrong. It's also dangerous and the bike shouldn't be used in this condition. If the wheel in the picture is properly in place in ...

Should amateurs install their own headsets?

The headset is a straightforward unit. Two cups are pushed into the frame with an interference fit and the crown race is smacked onto the top of the fork in a similar way. In the past, when I have had ...

Is this brake mounted incorrectly?

Yes, that caliper is mounted incorrectly. As others have noted, the pads are not contacting the rotor appropriately. Perhaps, the caliper is mounted using an adapter where none is needed. I have had ...

Installing a Bottle Cage without Mounting Screws/Threads

The approach I've seen is to use hose clamps to hold a bottle cage to the frame. Hose clamps are what (used to?) attach a car's radiator hose to the radiator, if you've seen that. If you have an old ...

Bottom bracket too tight to screw in by hand

Maybe double-check that there is zero debris in the threads. I ran into a similar-sounding situation and it made me very nervous given the stakes. It turned out to be small bits of finely-ground ...

Are bike saddles always removable from the saddle post?

Saddles are always removable from the seatpost or, in some cases, the seat mast. I am not aware of any arrangements where the saddle is made in one piece with a seatpost or equivalent part. Because ...

Zip ties to hold smart-lock on frame

Zip ties don't last forever, so you'll need to keep an eye on them and replace them periodically. P-clips would probably work.

Drilling and cutting rack mounting bracket arms

I've got a very similar rack and avoided cutting the arms only by using one screw per arm instead of the two in your first picture (at the rack end). Crossing the arms over and using one screw per arm ...

How to properly align the rear wheel to the bike (granny bike, single speed)

The underlying problem here is that the wheel's axle is moving in the dropouts. I think your wheel nuts are not biting down enough to properly resist the tiny flexes of the bike while riding. When ...

SRAM chain came with only half a powerlock

No, don't do that unless it's to limp the bike home. SRAM says not to and I've seen sufficient evidence it's for good reason. The theoretical/manufacturer-stated reason not to is that the press fit is ...
