Removing middle chainring
it’s usually possible by removing at the other rings, BUT by the time you messed around doing this, taking the drive arm off would have been quicker and easier IMO.
removing the granny ring allow you to twist the middle ring into a position that allows you to remove it…Posted 9 years ago

Believe me that would not be the case with this guy, it took him 2 months to replace his jockey wheels as he took both off at the same time and couldn’t figure out how to put things back together. Just been out to show him my chainset but didn’t really help as I only have 2 rings.
I normally just take the chainset off to replace rings as it’s so easy to do and I can give things a good clean. However the thought of this guy removing a chainset worries me.Posted 9 years agojulianwilsonMember
it’s to do with getting the middle ring ‘around’ the crank arm: i seem to remember having to have my granny ring off and rattling around the BB in order to be able to able to angle the middle ring around the arm: this was on fairly ‘flabby’ octalink cranks though so may be easier on slimmer ones. Still easier and less ‘tool-ey’ for the total novice than having the whole crank off though.
…i hope your mate has hex-key chainring bolts to do back up again. 🙂Posted 9 years ago
You’re not listening, the guy is mechanically incompetent and has zero common sense. Last time I taught him how do to something, and lent him my tools, he broke both my chain tool and chainwhip. He won’t be able to take a chainset off – no way. I told him to bring the bike in but he says he can’t ride it as it keeps sucking up in the middle ring.Posted 9 years ago
A guy in work needs to replace the middle chainring on his deore chainset. Now I’ve taken him through all the steps of removing the chainring bolts and out and middle ring etc but my mind has gone a blank on whether he can remove the middle ring with the chainset in situ. I’m sure he can but I can’t picture in my mind me having done so.
He’s a bit of a cack handed type so anything that can go wrong will.Posted 9 years ago
soobalias what do you mean by that – you seem to confuse argument with discussion.
Anyway he’s got no money to take it to the bike shop (long story but he has a gambling addiction and his wife won’t give him any money), he uses it for commuting and I have said why do you even use the middle ring but he’s fat and unfit. And I explained above that I would do it but he can’t get his bike to me and wants to do the job tonight and I ain’t riding 7 miles to his then 27 miles home. And I stop for a weeks holiday today anyway.Posted 9 years agoD0NKSubscriber
depends on ur pedals, if they are spds u can wiggle it off, flatties no chance. course you can take off the pedals too but if your going that far you can whip off the crank instead.
And an inept mechanic will struggle with drive side pedals anyway.
(trying desperatley to remember if it IS the driveside pedal that has LH thread)Posted 9 years agomike_checkMember
I don’t think the crank spider will be a problem, once the bolts are removed, rotate the chainring so the tabs on the ring are clear of the tabs on the spider and then manouvre it off?
I haven’t played with chainrings/spiders for a while tho cos I run bmx cranks and single ring but had a quick look at a pic and reckon it could be done, though I may be wrong.Posted 9 years ago
