Bike Maintenance for Beginners

I noticed the rear disc on my propel was rubbing on Wednesday, tried reseating the wheel with the brake on etc with no joy. Anyway noticed this morning when there was a bit of light on it that it’s slightly warped! It’s only 3 years as old as it popped up on my memories this week.

Luckily the wheels that came with the enigma have the same type and diameter so I’ll try swapping it as it’s likely I’ll be taking it to the races next week.

Although there’s not much pull on the rear brake compared to the front.

It was starting to worry me, don’t really want to use the enigma.

Not sure how it’s got warped though :man_shrugging:t2:

Doesn’t need to be expensive and is straightforward and kinda fun. I got a SRAM kit from this fella and it works fine.

All done, had the jockey wheels out to clean and refit.

Think it’s close to perfect except for one thing which I can’t seem to fix. There’s a squeaking when pedalling, like a small bird chirping type sound. Thought it was the jockeys but that didn’t fix it. Then crank out to grease the spindle but it’s still there. I can’t for the life of me figure out where it’s coming from or what to try next.

Think it when pedalling but when I stop the freewheel is loud enough to drown it out. With new BB bearings and a greased spindle, what else could I try?

Reckon I’ll get one some day. Doesn’t look too complicated really. How do you know if it needs bleeding anyway?

Does it do it when out of the saddle, it can be the saddle or clamp and only does it when peddling as the rocking motion sets it off.

Bike’s on the stand and spinning pedals by hand. So def not the saddle clamp

Pedals themselves?

Interesting, could be. Will switch to my other pedals to see if that does it.

Edit: Not that, having a feeling it might be the freehub rather than cranks or pedals. Mavic wheels apparently have a plastic bushing inside which can wear. No idea if that’s it but will strip it at the weekend.

Bike is going to be running like new before long.

Only if brakes get soft and squishy and replacing the pads and pushing back the pistons doesn’t fix it. Probably means air in the system. Or every time you disconnect the brakes eg to reroute hoses through new bars.

So very rarely!

So after successfully (?) managing to swap out my cassette and chain, i still suffered some problems on my recent long ride. At the start of the ride, before the rain, i did however experience what a silent and smooth drivetrain sounds and feels like! :rofl: I hadn’t quite appreciated just how bad it was!

Trouble is, during the ride the chain was slipping off pretty much every time i stopped, at lights etc, and set off under heavy load. I had to learn to go back up the cassette and start off much more gently to avoid losing the chain. Had a mate look at the bike and he’s said that me big ring is farked basically; which was my theory. I’d guessed that the old chain had stretched and conformed to match the chainring, then when i chucked the new one on, they just weren’t playing as nicely together. Does that sound right/plausible?

So it looks like more dollar dollar to keep that puppy running. TBF i think it’s the original one, now 3 years old.

Yes. Stuff will wear together and it will fit nicely, change some parts and the others no longer mesh together as they did

Yeah, had exactly the same thing with my Brompton. Put a new chain on and it was jumping all over the place, had to replace the sprocket too.

Almost certainly.

A stretched chain knackers everything else in short order as the load is only transmitted by one or two teeth instead of many.

Stick a photo of the chainring alone and the chain on the chainring. You can normally see if it’s farked

It’s definitely your chainring @gingerbongo - I meant to say to you when we stopped for the puncture. Completely forgot - it must have clunked 4 times or so when we were together :rofl:

Sounds like chain mating for sure.

It’s sometimes cheaper to buy a whole new crank then just the rings.

Good intel. thanks.

@adam - it got pretty scary in the proper London section when i was trying to bomb off at the lights amidst all the traffic. Twice i properly lost it and went flying forward into my own bars as a result! :roll_eyes: :rofl:

If i’d have bothered testing the new stuff out last week i may have known in advance! haha.

Question: can i just change the big ring, or does it make sense to change both? The small one has had much, much less wear. But i#m guessing this may be one of those ‘just change it all’ moments?

I’d say the big ring will be fine to replace. Like JGav said might be easier to just replace the crank though
