Any hope?

Took my bike to my LBS for just a general tune up and this happened. They said they don’t feel comfortable trying to extract the bolt and told me to take it to a machine shop. Took it there and they said they can’t get it out as well. Emailed the manufacturer to see if there’s a solution but waiting on their reply. May try splitting the bolt in two and getting it out that was as a last ditch effort? Was wondering if there were any other suggestions or do I need a new frame?

Somehow the nut that was holding the, cassette in place was loose, i don't know how that happened, but while riding the cassette started to slide back and forth and this is the result, what do I do?

I have a 2024 diamondback Yowie 3, and i want to do a full rebuild but i am afraid to take the housing out of the frame if there is no guide to easily put it back through

Cantilever brake question on vintage MTB..

Tech question.. help please. I'm attempting to fix up this mid 80's Stumpjumper that I bought. I tried replacing brake pads and found the original cantilever brakes to be very hard to adjust. I bought new basic shimano cantilever brakes (going for functional town bike, not period restoration). Today, while installing them I found the bolt hole/pivot post thingy was full of mud from a wasp trying to make it a nest. I cleaned out the mud, started installing the bolt that holds the brake caliper, it got stiff, instead of backing it out and cleaning it better I doubled down, went for broke, stripped it, it did not go all the way in. I eventually got it out with vice grips but before doing so I noticed that the spring tension was not working. I had to really wail on the thing to get it off. Now, I am wondering if I expanded the post/bolt receiver by driving the bolt in so aggressively while there was still mud in there? I know this is a total dumbass move.. I am a pretty bad bike fixer, learning everything the hard way.. but, has anyone ever had a similar issue? Anyone think I could grind down that post so the brake can pivot and the spring can function? I love this frame, I feel dumb.. any advice or punishing criticism welcome ... Thanks !

Shifting problems

I have an old bike. Last week I had the LBS replace the freewheel with a new shimano, new derailleur Tourney and a new chain. After a few rides I have noticed that the gears shift up smoothly, but down shift is going bad. From 5 to 4 , the chain is still on the 5 th cog or 4 to 3 the chain is stuck on the 4 th cog. It does move to the right cog after a few pedals but with a sharp clicking sound. I will be taking it back to the shop in the next few weeks. Is there anything I can do to fix this problem. It’s a 7 speed bike which I use for leisure rides every day.

Chain clicking and catching on the NEXT SMALLER cog (Trek Roscoe 6). Video attached.

Hey everyone. I'm going crazy trying to fix a persistent clicking issue on my Trek Roscoe 6.
As you can see in the video, the chain is seated on the 9th cog, but as it rotates, it keeps catching on the smaller 10th cog. It lifts up slightly along with the 10th cog, and then drops back down to the 9th with a loud click.
I’ve already tried adjusting the cable tension via the barrel adjuster on the shifter, but it doesn't fully solve the problem, shifting becomes bad.

The cable loom running underneath the frame on my ebike is catching on the front tyre

I weigh 120kg, the weight limit for the bike is 150kg. The first ride out on it I noticed the cable loom underneath the frame was catching on the tyre when the front forks were pressed right down. I immediately went home took all the cable ties off and insulated and wrapped the cable and redone all the cable ties tight to the frame. If I have the front suspension on air lock it is ok but if I don’t it is catching. If I turn left with the handlebars it creates a loop in the loom so it hangs down. The first picture is how it looks now and the second is when it just happened.

I have just got some strong self adhesive pads which im going to try adding and cable tie them on and add a half cut tube of garden hose where its catching for protection. Any advice or anyone got a similar issue? I’m going to upgrade the front suspension eventually so I will have more travel. Thanks in advance.

Putting tyre back on rim

Hey all, my first post on Reddit and it’s out of pure desperation. I’m about to crash tf out over this tyre. It’s late at night so I can’t go to a shop and I am a wheelchair user so it’s kind of important it gets sorted now. Even my emergency wheels now have a puncture. I’ve done soap, levers, brute force, zip ties, lubricating with my own tears and sacrificing my soul to the devil and I still cannot get this thing on. It’s a speedlite 24” tyre and every time I try to pop that last 20cm on the whole f*cking thing comes back off- I need my chair for literally everything. Yes I started at the opposite side to the valve, I have also tried starting AT the valve, the same issue keeps happening, if I pop another inner tube I am literally gonna scream- please help! Thank you🥲

Replaced 54T with 44T chainring. Chain keeps coming off.

I have taken about 10 links off the chain but the chain seems to come off the chainring if I go over a bump.

Is there any way to tighten the 7 speed derailleur spring, so the chain is more tight?

I am at a loss because I did this exact same thing on an older bike years ago, and never had a problem.

Thanks.

Surly Bridge Club Cane Creek 40 Headset

Hello,

I recently took apart my headset to figure out a creaking sound that was coming from the front end, it ended up being a misaligned front rotor/loose front wheel. I ignorantly forgot to keep note of which order I took the headset bearings off in and now as I'm re-assembling everything I've noticed a bit of a gap with the lowest bearing you can see in the photo where there is a little bit of brown showing.

I'm looking at pictures of similar bikes online and it appears there is no gap, whereas in mine there seems to be a pretty noticeable gap. Does this mean I've installed the bearings in the wrong order and would anyone happen to know which order they go in?

Thanks for your help!
