Correct me if I'm wrong...

...but I don't think my bike's supposed to look like this :oops:



Happened about half a mile from work this morning - cue some 1 legged pedalling for the rest of the journey.

Wahey! Powercranks for free!

You're quite right. The teeth on the big ring look a bit worn, and I think the correct way to photograph a bike is with the chain on the big ring. Otherwise it's fine, carry on.

Tyre pressure looks a little low

Pictures of bikes are supposed to show the drive side too.

rolf_f

A triple on a commuter bike. I dunno..........

EKE_38BPM

Very shark toothy chainrings.
Time for some new chainrings. Change your chain whilst your at it. Check your cassette for wear too.

Sod it. New chainrings, chain and cassette. Job lot.

That's a design flaw that is. It would have been way simpler to affix a small sticker to the top tube saying "periodically check that stuff is maintained before it gives way catastrophically and smacks your junk on the top tube"

Good grief man!

(or have you stolen Wiggin's mojo and just laid down excessive power?)

mitchell_inman

Jings - thanks for all the advice, guys. I'm ashamed that I could have made so many elementary mistakes when photographing my bike.

As for the drive train problems - Iooks like an ideal opportunity to learn some maintenance skills :?

Wheelspinner

I wouldn't worry. With pix like that, itboffin will be along shortly with a blank cheque to buy it. He can use the parts as upgrades for his newest bike.

Good attitude.

I don't know what tools you have, so I will run through everything I think you need to sort out the problems I can see:
Pump - Back tyre looks a little flat
New chain rings - It may well be cheaper to buy a new chainset than all of the individual rings
Chain tool - To remove the old chain and replace it with a new one
Cassette removal tool - The clue is in the name
New cassette - I can't see, but I guess you may have wear on your cassette too, judging from the condition of your chainrings
Crank removal tool = Again, the clue is in the name
Bottom bracket removal tool - To remove your busted BB, now we are getting to the root of the problem
New BB - To replace the busted one.
Various tools - Socket set, allen keys etc
Grease
Threadlock

Remove your rear wheel, remove your cassette, remove your cranks, break your chain, remove your BB (make a note of the part number and replace like for like or buy one with the same dimensions).
Give the bike a good clean including the threads of the BB shell.
Install new BB. Put grease on the threads or they will be a git to remove in the future.
Install new cassette, break new chain at the same length as the old chain and install into frame.
Either install new chainrings or install new cranks. If installing new cranks, grease the spindle of the BB and use thread lock on the crank bolts.
Install rear wheel.
Give everything a good look over and a shake before going for a test ride. This is where you spot your stupid mistakes (incorrect chain routing through the rear derailleur, chain not going through the front derailleur, pedals not at 180° etc).

Go for a spin then come home with a smile on your face as you have just done what is probably the hardest thing to do on a bike and now your bike feels new again.

Crack open a beer and watch the cricket.

EKE - thanks for taking the trouble to do that.

My wife bought me a lovely set of tools last year - looks like time to use them. Luckily, I have another bike to commute on in the meantime.

EKE_38BPM

No worries.
Seeing as you are in Edinburgh, instead of taking the other bike to work, how about using the tram?

Sore point?

mitchell_inman

Tram - what's that? Oh, you mean the big hole in the city centre where the Council chucks our money :evil:

I'll stick with using the Sunday bike for a few days...

After the purchase of a decent crank puller and a huuuuge spanner (to get purchase on the bottom bracket), the offending article has been removed...



and looks like this:



It's been a complete PITA getting it all apart - much wielding of big rubber hammer to get the cranks off, and I really didn't think the BB was coming out.

Question is - can I get it all back together???

Putting it all back together should be much easier.

And if you're really lucky you'll have some bits left over that'll make for a lighter bike ;-)

Use a liberal smearing of copper grease prior to reassembly. Will make life much easier if there's a next time.

Awww, now you've just gone and broken it.

Could do with a good clean by the way.

Disappointing.
