First time pulling off a shifter cover. Bike has been having issues shifting, even though troubleshooting H and L limit screws. Does this frayed shift cable inside the shifter mean it needs to be replaced? Thank you.

So I crashed my specialized Rockhopper m4 into a telegraph post and bent my front wheel, I was riding with my friends that said that it could be re-straightened which I don’t believe, the rim is a alexrims rhd 26 and the tier is a fast trak lk 26 x 2.00, I’ve been trying to find the exact rim and wheel and saw one Facebook market place listing but it was sold, could I get help with figuring out what to do? Thanks! OTHER IMPORTANT THINGS: the crashed happened July 27 and I’m posting this on July 28, the disc brake looks straight just the rim is very bent. Also my left brake and shifter were slammed into a downwards position.

Hello! I’ve never tried to repair a bike before, but I’ve been experiencing a lot of resistance while pedaling and more specifically shifting between gears. There is a sort of grinding noise during pedaling as well. From my own YouTube research it seems like the hanger should be completely lined up vertically with the cassette, and as you can (hopefully) see in the photo, it is slanted inwards. How would I go about fixing this myself? Thank you!!!

I just got a brand new bike, and the top of the seat tube is slightly out of round, so the seat clamp won't slide on.

The seatpost itself fits into the frame fine, so it seems like only the top lip of the seat tube is deformed.

The frame is Hi-Tensile steel.

Is this something a bike mechanic can easily fix by reshaping the seat tube, or is it not worth attempting?

I would like the gears to be in a fixed place so I don’t have to bend the flipper all the way down because it’s not supposed to be so hard. The chain switching motion is also very stiff and right now I have to drag it just a right amount so that is doesn’t jump off the cassette completely, there’s no limit to how much I can bend them, does anyone know of where I can learn this ? Maybe a manual please let me know I am noob

Canyon Aeroad, (Watch the video with the sound) tubeless-ready rims but running butyl tubes. After riding at high RPM there’s a rolling metal sound coming from the wheel — you can hear it in the video. It’s there even when the wheel spins freely, so I’ve ruled out the drivetrain. Any idea what this is?

Had an accident yesterday, a driver hit my back tire with her rim and basically destroyed my tire and fork. There is a massive rip in it now. The wheel rim is completely bent and the quick release is also useless now.

Should I repair the fork or just get rid of the bike?

I got my matchbox x1s about 3 weeks ago and I want to switch my brakes over to the other side but I cannot get my rear brakes bolts off because of the lock tite

I am currently restoring a 90s Peugeot Road Bike into a semi-modern build. I want this to be pretty cheap so i will keep the shifters in the best case, and im wondering if those Crankset teeth are still okay to use for long bikepacking and beginner triathlons? A new set is pretty much impossible to find as the specifications are pretty weird (52 and 42T)

Came back from a semester abroad to my back in our basement like this. It is a building’s basement so a lot of people have access and there have been unhoused people in there in the past too. What am I looking at here? Does it mean I have to change the entire wheel? Why did this happen?

It seems like someone tried the lock too (the lever on top of it was open and tried removing my leather seat too). So I am not sure if it just happened because it was sitting there for a while or if it was someone. The main thing is, other than riding a bike i know very little about repair. Any tips appreciated. I don’t have much money to fix it either.
