Service?

[Sam The Man]

I have (this afternoon) picked up my bike from the lbs, after having the chain, cassette and chainring replaced. almost 200 dollars later ,33 of which in labour, i realized once at home that the chainring is on back wards. now, as this doesnt affect the performance of it, it doesnt have ramped pins or anything, it just doesnt look nice (it is obvious which way it goes on), and im not sure if thats what i expect for my money's worth.

on top of this, when the gear runs through the chainguide peddaling hard, a series of three or four louder clicks are audible above the normal whirring of the guide on the downstroke of the right crank.

is this what i shoudl expect after a 200 dollar service?
also, if you can put a finger on whats hapening with my drive train noise, that would be of great help.

Nope, ask for a refund or a free service next time if you want to hang around with them anymore. orelse change bike shops

3 - 4 clicks that occurs when cranking on the right pedal? I have a hunch about that may be causing this. Just some questions first.

What sort of bike?
Is it a consistent noise or semi random? Does the same clicks occur every stroke?

Sounds like your BB is not lubed and tightened properly, simply fixed take apart BB Grease everything re tighten everything.

2005 Kona Stinky, is consistent when your pedaling hard

hmmm... i thought it may have been something like that, although when i asked the lbs mechanic a while ago if B/B's could be tightened, he said no, and that i would need a new one when it got so loose that the chainring was rubbing the chain against the device (which is why i suspected it may have been this).
what sort of grease do you mean? triflow? or something different? and what tools does this require (taking the bb apart)?

thanks heaps everyone, keep it coming

unfortunately, it does not. the american brand products recomended are not always found in AUS, (and parktool tools, which are expensive and extensive being recommended left right and centre) and i have only a remote understanding of how a bottom bracket works and what it comprises of.

Take it back to the bike shop and politely ask them to fix it?

When the LBS put my chainguide on upside down, I just went in and asked them to fix it up, they didnt mention any money.

You will need allen keys to remove the bash plate and then take off the chain ring and put it back on the correct way.

Try tightening your crank bolts to remove the creaking sound. Generally, it requires an 8mm allen key into each crank arm. Tighten those bad boys up. If you have been riding for a long time with the creak, then it may have worn away at the spline which is not too good. If it only just happened, it should be sweet. Sometimes, the outer cup of the BB gets muck under it or isn't fitted snuggly with the main piece of the BB. This can cause noise. If the noise wasn't there before and the mech's didn't touch the BB, then it is most likely the crank bolts.

Depending on what cranks you have, you may or may not need a crank extractor to remove the crank arms to get to the bottom bracket. To remove the bottom bracket and remove any dirt/dust/whatever and regrease it, you will need a bottom bracket tool and a shifter or socket wrench to turn the bottom bracket tool. The type of BB tool you need is determined by the type of BB on your bike.

The creaking may also be coming from the chain ring or the pedals.

I would suggest taking it back to the bike shop and politely saying that the chain ring is on back to front and there is a creak that wasn't there before. If they are nice, have a chat to them about what the possible causes and solutions to your problems are so that in the future, you can do it yourself.

unless you can get the chainring off over the spider and crank .. your going to need a 4.5( i think?? ), 8mm allen key and a crankpuller.

to tighten a bb you will need a bb tool(the thing on the left)and a big ugly shifter

This sounds silly, but if the noise is still there, just grease your seatpost and see if that makes it go away.

I had a clicking noise when I was pedalling before. Took me ages to figure it out. It turns out it was the new Thomson seatpost just lightly tapping the walls of the seat tube.

It is probably not that at all, but it's an easy fix to try.

ive been poking around at everything and inspecting every little detail around the chainring/cranks, and i noticed:

my ethirteen guide's bottom roller/cog, sits on a plate, which is then bolted to the boomerang. The end with the two bolts that go into the boomerang is sitting flush, but closer to the cranks, it strays off a bit, so there is about a 1.5mm gap between the boomerang and the side of the plate closest to the
cranks. the chain rubs on this when the right side crank is on its down stroke, especially when pedalling with force.

this revelation is great, as i know what is wrong, but there are two problems:

1. i have tried to ben the plate inwards a bit, so that it sits flat (aftertaking it off and cleaning it) but the plastic is quite elastic, i.e. it returns to its original shape.

2. the fact that the chain only rubs on the downstroke of the right crank, along with close inspection, shows that the whole chain guide is not quite in line with everything.

Are warped plates a common issue with ethirteen?

Ok so now you have done that you cant get the shop to fix it :rolleyes:

Good one..........:rolleyes:

[cheggy]

That's a pretty common problem. I wouldn't worry about it. I don't think that will cause creaking sounds, more of a light scraping sound as the chain rubs against the plate.

Creaking when applying force to the cranks is most likely the crank bolts or bottom bracket. Take it back to the shop if you don't have the tools to do it yourself.

i know its late but the lose bb is play in the bb not an undertightened bb. the sprocket was aligned correctly as the bolts sat in the receses in the chain wheel which is what thier designed for and generally if the ring is fitted to look nice with the writing to the outside where its visable then quite often there will be slight (only slight) warping in the ring due to the pressure pulling into the receses. hope this helps a tad. other than that i can do some of your repairs when needed man.
