Chain wonkiness?

rubez

Should be OK, but I'll check.

Would have thought the rear wheel would have likely been the problem since that is feeding the chain towards the front derailleur.

So, I'll check another wheel.

I have a plastic spacer on before the cassette. Maybe an 8-speed cassette, with no spacer would be more stable? I assume an 8-speed would fit without a spacer.

Pictures/video blah blah blah?

Help us help you. Then seek help of a different kind.

This is comical.

What happens when you go for a ride? You know, when you get on it and move the pedals, apart from it being a shite mountain bike of course.

rubez

you are an attention seeking douche.

Do you make it your own business to spam in each and every thread?

Since this site is under threat of getting shut down soon, how are you going to spend your days then?!

Twelly

Oh I hope they don't shut it down, where would I keep up with the adventures of rubez!?

Since, say the derailleur is fully rubbing against the chain, and I slowly bring it out with the limit screws, it will start to clear the chain, but it will still rub on and off the chain - so it must be moving side to side...

99% certain that will be a buckled chainwheel, the chain goes onto the chainwheel right by the front mech, so if the chainwheel is buckled the chain will move side to side where it feeds onto it.

Just for clarity, who is the attention seeking douche? Chunkers or TwellySmat?
It could be important.

Looks like all new stuff to me.

did you take the pics with your phone........?

rubez

A buckled chainwheel affects all 3 chainrings?

Yes I took pics with phone.

Is this on good authority?

I'll probably get some work done rather than laughing trying to help simples

rubez

Future is going out the game it seems, so I better hurry and get this MF'ing gremlin fixed!

Is the spider bent?

I blame the Crudcatcher. There is enough evil in there to send any company into liquidation.

I think that's a bit of a personal question!

I think it all works properly and nothing is wrong. The components are low end so bound to be some misalignment issues. Just go ride the bike.

crudcatcher was the only good bit of this forum

Buckled chainwheels are rare supposedly, and since the chain is wonky in all 3 rings, not to mention it is still new, this is unlikely at best to be the problem.

Just effing take the chain and front mech off. Spin the cranks and observe all three rings. Do they run true?

If not, then
Bent rings, bent spider, bent crank axle or mis-aligned BB.

Look at you with your expensive shite.

Apart from the go ride bit, that is utter rubbish.

Or better still, leave the front mech in place and see if the chainrings are moving in relation to it when viewed from above; use the mech as a useful reference point.

Will have a close look at it, it is just a bit of a bastard having to do it upside down, since I don't have a stand.

You can turn the chainset backwards with the bike the right way round

Model number of rear mech please! What are the cassette ratios? Lack of meaningful info is why these threads descend into farce.

drlodge

I'm completely lost as to what the problem is that we're trying to solve. Its already been established that the rear derailleur is out of alignment, until that is sorted I don't see we can move this forward.

You think that is the only reason?

rubez

Not sure if you are serious... make and model already given multiple times - not that they matter.
