No need. The crankset is fine. This thread is a variant of the semi-frequent ones where people who suddenly notice the uneven tooth height on their chainrings complain that the rings shouldn't have worn that badly after only 100 miles of riding. As Peewee Herman would say: they meant to do that.

Be warned, bicycle mechanicing is not the same as other sorts; well it can be more like setting up a multi-carb system than changing a water pump. More modern stuff is more likely to come with instructions including torque settings and adjusting procedures and even digital diagnostics, but there's still a lot of setting stuff by eye or ear or feel.

Pot, kettle, black

This doesnt even make sense.. im not a parts changer bro. I work on equipment... i promise bicycles are easy. Actually what got me into turning a wrench as a kid. Not being mean its just a fact.

2.4 "psi"

Electric drive motor out of a crown forklift


Maybe new Ebikes can get complicated once they involve can-bus systems but even then.. or a wet brake system on a toyota im not scarred hahaha you called it mechanicing

Thank you fir the information with the cheap versions of shift pins. Thisthread been interesting in who is and isnt knowledgeable sure im new to bicycles but whoever said its worn out is incorrect its a garage kept barely rode find! Still has factory tires on it with nipples 🤣😂

Not being mean but this is exactly the sort of mistake that auto/equipment mechanics make when they think their skills translate directly to bicycles. Several of us here have considerable experience with cars, trucks, motorcycles, but I don't think any of them would claim that helps much with bicycles. Does my experience welding car bodies transfer to my ability as a bicycle frame builder? They both have "too hot" as an important factor, but beyond that they use different processes, different materials ...

Tbh if your a quality welder it 100% should transfer i should be able to give you a schematic and you should be able to 100% build it as a quality welder. Thats literally there job. The too hot is just silly... it either is a good weld or isnt. Ask an iron worker.
that analogy is just dumb. Did I start in cars? Sure. Flat rate sucks went to RVs and trailers. Then moved down south and went to tractors and forklifts. Thats like saying because I only have car experience in dont know how to fill a tractor tire with washer fluid.
Anyway
Same thing with a quality mechanic. If it has moving parts he should be able to figure it out and fix it. If not hes a parts changer. We do t have the choice i. The field sometimes. I get the point of feel and eye. But if you dont have that natrually you prob should put the wrench down. Add repair manuels ontop of that and yeah if a trade mechanic cant do it.. A bike doesnt even have as many parts as a single wet brake system or have enough hydraulic pressure to cut you to the bone. Theres nothing on a bicycle mechanically that scares me to fix. Even if it takes me a try or 3. Its a $50 junk yard bicycle not $150k forklift or $400k combine. Im not scared of breaking a part that I can find in the garbage pile on bulk garbage day. Again not being mean its just the truth even your crazy $6000 carbon bikes. I deal with batteries that cost more lmao if im on here asking a question its because I haven't touched it yet. Ntm the tools...

the eliteism here is absolutely wild. I always knew cyclists were snobs (not all of you) but damn this forum set it in stone. God forbid im confident in myself and my work to work on a 30 year old bicycle. Fk what i know about equipment and systems a bike tech would scream in horror just looking at.

How about mirror welding in a nuclear reactor?
If you have mechanical aptitude, you have mechanical aptitude.
Bicycles still have some "quirks" compared to other mechanical things.
I served an apprenticeship as a Boilermaker in Puget Sound Naval Shipyard and I've assembled, calibrated & repaired state of the art optical oceanographic instruments.
I still learned more "new stuff" on bicycles than I would have expected.
You need to deal with more bicycles & repairs before you presume everything is simple.

You learn who to ignore.
Some just want a high post count and just have to have the last post, no matter how inane.
some have the thinking level of a 10 year old. IF they haven't seen it, it doesn't exist.

Just ignore the idiots.Don't feed the trolls.

you really need to learn to adjust post type pads in canti brakes.
get the KoolStops.
and just wait until you get the chance to hear a CF seatpost splinter as you barely over-torque the seatpost clamp...
i retired from general mechanics(M/C, ATV, Ag, Const., and Golf Course maint. equipment, mostly), and came back to bikes as a hobby... i still have a ton to learn as i build and repair what you describe as "simple". i once diagnosed a running problem on a Kubota KX-080 excavator that was caused by........ a pile of about 2 dozen apple cores behind the seat. 3 other mechanics had not paid notice to the acidic garbage that corroded the main harness connections, including the fuel solenoid hold signal wire, buried deep inside a foot of cast iron bulkhead.....
before being a general mechanic i assembled, dialed in, operated, tore down and moved large Rock PA systems, while being the stage manager too.... it was far easier than some bike repairs.
build a wheel up soon.

most skilled welders either refuse to weld bike tubing, or quickly learn to refuse to weld bike tubing, btw.... a highly skilled TIG Welder can usually do ok at it...

remember.. the correct lever pull ratio, quality cable housing, and new/fresh/correctly set up pads make the true difference in rim braking, not a bunch of opinions on an SM site.

and i'd advise dripping some pb blaster into the freewheel..the grease in there is as old as the rest of the bike... the pb will loosen it up for a while...

and, have you done axle bearing, headset, and bottom bracket grease renewals yet? they need it too.
those tasks require a selection of special bicycle tools to complete properly.

ever revived a dead Onan gen.? been there, many times... the Green Monster hiding under many old RVs.
that same engine is used in an array of Golf equip. too. the first one i rebuilt was buried deep inside a cart path sweeper.

You supposedly came here looking for advice, but then your inferiority complex kicked in, and you apparently thought you could impress someone by telling how you work on bigger bits of metal than we do. As I've been telling you, that's not how it works, unless you're going to demonstrate your watchmaking skills with no prior training.

I have no doubt you’ll be able to work on bikes. They aren’t all that complicated but there are some quirks you’ll have to learn along the way. Probably nothing compared to internal combustion engines but the quirks can be a bit maddening.

tbh man, I dig it! Absolutely theres always more to learn in life. Maybe thats what excites me, not sure. Im like a moving parts nerd hahaha but you right bout the trolls homie I dig it
