r/bicyclerepair

I went to a local bike shop near me. The reason being was that my bike started clicking. I couldn't hear it just felt it. They guy took a chain tool and did something with the chain. Then pretty much immediately after said that i need a new chain. He also said that the current gear wouldn't be accepting of a new chain(thats if i heard him correctly. I'm not sure if what the guy said is true or not. Just thought I'd get a second opinion.

The drive train is definitely not in line so that is definitely an (or the issue) also I don’t know if the chain is too loose and I need to take a link or few out anyway. Anyone know a quick and easy fix. The sprocket appears to be pushed away from the bottom bracket quite a bit but I don’t see any spacers to see why. I haven’t messed with that yet, but that was a thought also. Idk when it comes to derailleurs I have somewhat limited knowledge. Any help is greatly appreciated. Thank you.

As the video said, I went off a jump and and heard a clank, I looked down and it looked like this. If this is fixable, please tell it will be greatly appreciated.

Any pointers on where I should start with this issue please? Very little movement in the hand lever

I have no idea what's wrong with my derailleur. I can't seem to tune it correctly. I've been trying for 10 hours

And one I nearly get it in tune, it always skips the 7th gear. Please help

Can someone tell me what part this seat post cartridge is or send a link?

Looking for what this part is called and where to buy it? (Pointing to it in the photo)
I was at a bike park and dented the part just on the inside of the crankset. It’s only on the naked side of the crankset. Could use some advice.

i think the derailleur is working fine but the shifter does not cause movement in the derailleur cable i.e. shifter doesn't change the tension in cable.

What could be the issue here.

I had a bit of a tumble with another cyclist. I slowed down quite a bit, and the contact was with my front tire and his frame. After that, I’m guessing his pedal scratched my frame, My bike is new, do you think it’s fixable?

My bike is an Orbea Alma H30 2024. I bought it about a week ago, and it arrived 90% assembled, I only had to install the front wheel, handlebars, and seatpost.

I noticed that when I pedal, especially in gears 10–12, I can feel a vibration through the pedals. I can also visibly see the chain vibrating/wobbling while I pedal.

I also checked the rear wheel and there seems to be a very small amount of play if I force it from side to side.

And if you listen carefully, you can hear a weird, irregular sound from the rear wheel. I’m honestly not sure how to describe it, it almost sounds like the wheel isn’t running perfectly true or something is misaligned.

The important thing is that this has been happening since the very first time I rode the bike.

I have not ridden it aggressively or done anything that could have caused damage. I’ve only used it normally.

I contacted the company I bought it from, and they told me that they don’t do adjustments/tuning on bikes ordered online, only on bikes purchased physically at their store.

I’m honestly disappointed and I don’t know what to do. Is this normal, or does something actually seem wrong with the bike? What should I check first?

it seems to have 2 glaring issues the front spiked circular thing the chain goes on is bent (can that just be hammered back into shape?) and the brakes are definitely messed up though i couldnt say how (im not used to bikes with hand brakes)

what to do/where to start on this? any help is appreciated! i want to learn the ways of bike repair and this seemed like a decent first project.

Recently crashed my bicycle. The front brake line has been squished (shown in pic 1). The front brake is soft on the first press but if I keep pressing it the pressure will return. Then after a while it'll become soft again. It probably has some brake bleed. I have 0 bicycle repair experience and I'm wondering if the entire front brake system needs to be replaced or regular brake bleed maintained would suffice? If the brake lines needs to be replaced is it possible for a beginner with some patience to do it? Or specialised tools are need?

I am in need for your advice :-) The inner chainring and one of its bolts are rubbing against my carbon BB shell. I already tried centering the small chainring, but with no success — there is still basically zero clearance on one side.

What should I check or replace? Could this be a BB/crank issue?

Thanks! :-)

When i try to shift the gear using the shifter, the derailleur doesn't respond. And after 2 clicks the shifter becomes completely jammed.

I think that the problem is not in my shifter as when i unlinked the derailleur cable from derailleur the shifter moved freely.

Pls watch the video to better understand my prob. Sorry for the noise in the video

Wondering if there are any realistic options for repairing the corrosion on this frame? I've seen this before and I've not had any experience treating or repairing this type of corrosion with any lasting success. Just seems like a cancer that keeps coming back and spreading......
