Repairing a 28 year old bike given to me in pretty good condition. I've been working on it a lot hoping to ride/commute. These pedals are old, some bits broken and I want to replace them.

I've tried everything I can think of. I am pulling/pushing to the rear of the bike with all my weight. I have used PB Blaster. I've put a heat gun on it for at least 5 minutes. It just won't budge.

Any ideas?

Hi,

I've got my old yeti cross country hardtail from high school that I want to put back on the road as a gravel cruiser, cross country, light mountain bike with the family.

The chain is skipping which I'm assuming is a good indication that my drive train needs some replacement. Its never been replaced as long as I've owned the bike (that I remember).

Right now its a 3x7, and I wanted to get some recommendations/advice on what I should replace.

From what I can tell is:

Option 1, replace with a new 3x7 system

Option 2, replace with a 1x9, 1x10, 1,x11, 1x12 system.

Once I figure that out, then I need to get parts.

My initial thought is to keep it simple and stick with the 3x7,

If I go that route, what I think I need(Prices in CAD):

• Front chain rings I think its a black spire, which is now defunked (it is bolted so maybe I can replace the old rings, although I'm guessing its not worth it.) and crankset. - replace
  • FC-M361 $80
  • or FC-M311 $50
• Front derailleur looks pretty beat up - replace
  • Shimano FD-M310 $25
• Chain - replace -
  • Shimano CN-HG71? $40
• Cassette - replace -
  • Shimano CS-HG200-7 (12-32T) $30 CAD
• New cables - replace
• I think the rear derailleur is newish - reuse
• Thumb shifters are still ok as far as I know - reuse

Total cost - $175

These part picks are basically me chat GTPing and googling, I'm totally open to suggestions.

$175 bucks seems very reasonable to me, so if there are suggestions on slightly more $ options I'm open.

Thanks

I dinr know why it does this but it happ3ns. Can anyone teach me how to fix it please?

I posted here a few weeks back about my project bike (Raleigh Medale, 63cm steel frame) that I've changed from a 5 gear bike, to a 7 speed (Shimano Megarange to help with the hills) - which required a Shimano Megarange deraullier...

My only issue now is, that ive had to install x2 deraullier hangers (1 on both sides) to ensure the deraullier is fitted (no deraullier hanger on the frame) but it means the wheel keeps pulling out when theres a lot of power on the bike (im a 120kg).

Any ideas;

- can I get anything welded to keep things in place, and should I?)

- is there anything out there that's a part that would solve my problem?

Any advice welcomed :)

I bought an older Avanti Giro 51cm that was already bought secondhand and used as an indoor trainer by the seller I bought it from. There’s clear wear on some of the parts, could I please get help on how to go about fixing them and removing rust? Completely new to bike maintenance by the way.

Can this broken frame be welded or ist it cooked ?

Took a spill and my bike took a small dent on the part of the rear triangle. It’s an aluminum frame

Apologies abt the slight rant in advance!

Tbh I think I’m 99% sure that these are either beyond repair or not worth the money to try and fix.

I’m completely new to bikes and was offered two bikes from one of my coworkers as I mentioned I was thinking of getting a bike to commute to work but wasn’t bothered to pay such a hefty sum at once as I was saving for something else. I was also aware my work offers a cycle to work scheme but I was debating whether it’d be worth it as I’d be leaving my job soon anyways so I’d have to pay a lump sum anyways when I eventually leave.

Initially, my coworker heard that I was looking for a bike and asked me to send my address as they had two old bikes that they don’t use and could give them to me for free, and I did bc I knew if I didn’t send it then I’d probably forget to later. Two hours go by and I thought they hadn’t seen my text as it didn’t come up as read and they hadn’t replied. And tbh I thought we would begin discussing when to drop it off and talk a bit more abt the condition of the bikes but to my dismay my coworker had already dropped it off at my house while I was out after work. I didn’t get the chance to ask them to send any pictures of the bikes either as I wasn’t expecting them so soon. So my dad essentially opened the door to what looked like a random person dumping two bikes meant for the dump outside our doorstep!

When I got home my dad was a bit angry and he made it clear that it was insulting that my coworker thought they could drop the bikes off in their conditions. They didn’t even bother to clean them or anything but in my opinion I don’t think cleaning it would’ve made any difference! Once I saw them I thought that it’d probably be worth my money to go on the cycle to work scheme than try to revive these but I was wondering what others might think first so I decided to post this here.

I definitely should’ve asked for them to send the pictures of the bikes in advance so it’s my fault for not communicating that but I honestly didn’t think they’d send them mere hours after chatting.

Any estimations of costs and opinions would be greatly appreciated!

My friend ask me to hangout and strolling around the city with bicycle, n then I go to the barns where I dumped my moms bike, it's been about 8 years abandoned,

is there any cheap solution what I should replace n what I shouldn't so that I could save more money

PLEASE HELP I don’t know what it is

These were sold as tubeless ready rims. They seemed to seal fine EXCEPT that I could not get a seal with the Schrader tubeless valves I used. The width of the valve seemed to be impinging on the bead so I kept losing air there. I gave up and used tubes but should I try again?

I have a 2014 Trek FX 7.3. The bottom bracket is creaking like crazy, so id like to replace it. I need a removal tool in this style, however my bikes BB needs a 16 tooth version where every 4th tooth is double wide like i drew up here. I have not found been able to find any tool like that. Park Tools BB identification guide doesn't even mention this kind. Can someone point me in the right direction here?

My friend just got a Primos Superdame that comes with LTWOO eGR groupset. Built up the bike, but the derailleur was pre-installed. After setting everything up, we noticed that (a) the chain looked loose on the smallest sprocket (b) the derailleur moves back and forth on the axis of the swing arm (c) the b-limit screw does nothing (d) the upper jockey wheel makes contact with the cassette. Anyone know why this might be? Is the derailleur installed incorrectly?
