I feel like I’ve never properly cleaned my bike. Actually it’s more than a feeling. Its a truthing.
Partly (mainly) this is because I’ve never had the confidence to take the dirty bits apart in order to give them a proper deep clean.
The last time I took my bike to my friendly local bike mechanic, I got a friendly rebuke. As he replaced my broken front derailleur, he noted that the teeth on both the cassette and chain rings were worn. The chain was stretched. The rear hub was on the verge of knackery. The cause: infrequent (and ineffective) cleaning.
After returning from our holiday in Cornwall, where both long motorway journeys saw the roof-mounted bike being doused with finest English summertime rain and road muck, I decided to rectify past transgressions. I would give the bike, and specifically the drivetrain, a really good clean. And this would mean that an incompetent would be taking apart his bike (and hoping he could put it back together again).
I thought I would record my ‘journey’ to share on this here blog, perhaps to share some useful information, but more to provide fellow mechanically challenged people with the confidence that they too can destroy a bike and then half put it back together again.

Let The Crank See The Shaft
Unlike almost our entire holiday in the south west (of England), on the ‘Day of the Drivetrain’ the weather was glorious. Mother Earth was clearly taking the pizzle – she knew I was back at work the following day.
Step one was setting up the ‘workshop’. This consisted of an old door on two plastic sawhorses. I then emptied the contents of the bike cupboard in my garage to see if there was anything useful.
Behold the ordered chaos:
I got out the mini digger as well. You never know when one of those will come in handy.
This is not at all interesting but, from left to right as you look at t’ photo, we have:
- my bike toolbox – containing chain whip, pedal wrench etc
- my crate o’ cleaning stuff (and spare inner tubes)
- my ‘dirty bowl’ (formerly resident in our kitchen) containing brushes and rags
- a plastic milk container (which I reckoned might be useful); and
- my copy of
Zinnand the Art of Road Bike Maintenance(which you can buy on Amazon here).
In the bottom left is a really good set of hex keys (or allen keys). I got mine from Screwfix, which is my favourite shop (and will mean nothing to US viewers).
Do You Need A
Workstand To Clean A Bike?
In short, yes.
In the photo below we have my bike

Fiddly tasks are conducted at a height where you don’t have to bend down. You can spin the pedals and change gears without simultaneously (somehow) lifting the back wheel off the floor to allow it to turn. You can also spin the bike around in a pleasingly professional manner in order to work on (or clean) different parts of it, whilst you yourself remain in one (pleasingly professional) position.
The only hassle factor of the stand is getting the bike up there in the first place, and remembering to catch the rear wheel as you loosen the quick release skewer and suddenly have it drop off the bike. Back in the day (or 2015 as it was more commonly known), I created a short video of me putting my bike on said
It seems I chose another part of the building site (our home) on that day.
Okay, moving on. Next step was to remove the chain.
How To (Easily) Remove Your Bike Chain For Cleaning
At the time of the rebuke from my (otherwise) friendly local bike mechanic, Mark (for that was, and is, his name) installed a quick link (sometimes called a master link) on the new chain in order to make it easier to remove. The theory being that if it’s easier to remove, I would be more likely to remove it and clean it … [embarrassed silence] …
It turns out that once you have a bit of grime on and in it, a quick link ain’t quite so quick to qu-emove. You have to sort of push it together, whilst squeezing the middle, in order to disengage the pins and slide it apart (yes, I know, you’re none the wiser).
I should really have done some research ahead of time, where I would have discovered (and bought) one of the following specific tools:
(Which is a set of Park Tool Master Link Pliers).
Unfortunately, being a general tool myself, I didn’t have the specific tool. So I resorted to Youtube for solutions. I tried a few of the options, including one involving string (in the absence of spare brake cable) where you try and pull the link apart (I couldn’t get purchase).
In the end I resorted to a bit of (gentle) brute force involving a non-specific tool:
Having used a set of non-specific pliers and just about avoid causing irreparable damage to the quick link, the chain came apart. In the photo below you can see the two bits that make up a quick link.
(Remember this image above – I’ll refer to it again in just a moment).
Degreasing The Bike Chain
With the chain off the bike, it went straight in a bath of degreaser. Lucky chain.
How about that (now) for a fine array of degreasing and regreasing product?
The degreaser in the bottom half of a milk container (I told you it would come in handy) is made by bikehut (of Halfords and Cycle Republic fame, if you’re in the UK) and comes in a rather fine shade of ‘slightly dehydrated urine’.
It would appear that the greasy gunk on my chain was more than a match for the yellow dye in the degreaser. Or perhaps the degreaser was more than a match for the gunk, in that it seems to have removed a job lot of it.
Keep Hold Of Your Quick Links
Now, recall that photo of me holding the chain, showing the two halves of the quick link. Well, interesting story (yeah, right).
Between that photo and the one of me dangling the chain above the unused degreaser, you will note that one half of the quick link had gone AWOL. Which I only noticed some considerable period later, when I’d taken the chain out of the degreaser, wiped it down and left it to dry.
Cue 20 minutes of scrabbling around in the dirt, trying to calculate (using maths, physics and druidism) where I might have flicked the ickle linkle. Happy bunny I was not. Amazingly, given the less-than-clear “workshop” floor conditions, I eventually found it (and gave it a damn good
How To Clean Your Rear Derailleur (When You’ve Never Dismantled One Before…)
Right, moving on. With the chain out of the way, I decided to take apart the rear derailleur. Because why the hull not?
Actually, the main dirty bits of the rear derailleur were the two jockey wheels, and whatever that metal brackety thing is that holds them in place (perhaps the ‘cage’?). So that’s where I focused my dismantling efforts.
A close up of one of the jockey wheels demonstrates that they were scoring highly on the gunkometer (and clearly I used a Park Tools Gunkometer for my measuring):
In addition to allowing me to share (vital) images of my endeavours with you good blog readers, taking photos of the various parts in situ (or close to situ) were an attempt to record visually how to put the bally thing back together again.
As I publish these images, I’m starting to get somewhat embarrassed at the state I allowed my drivetrain to get into.
Anyway, for completeness, the photo below shows what the rear derailleur looked like with both jockey wheels removed, as well as the ‘brackety thing’. With the jockey wheels out of the way, I was able to get in and clean the inner workings of the derailleur when I gave the bike frame a wash.
The removed bits of the derailleur got a go in the degreaser bath before receiving a thorough wiping. I was a bit surprised at how plasticky the jockey wheels were (for they are made of plastic) and how unsophisticated the whole ‘bolt and bushing’ arrangement was.
I immediately ‘hit up’ Google to see if it was worthwhile upgrading to jockey wheels with bearings in them (similar to wheel hubs), ideally in some shade of your blingiest anodised aluminium.
The short answer is that the reduction in friction improves your performance by only a fraction. So probably not worth the money. (They’ve gone on my Christmas list though. COME ON! They’re anodised aluminium!)
Anyway, behold what a reasonably clean rear derailleur looks like. Also behold some proof that I was able to put it back together (turned out not to be too difficult). I even put a little grease on the threads of the bolts before screwing them into place (ooh, get me).
And so we turn to the chainrings.
Cleaning Road Bike Chainrings
From the image below, you can (rightly) surmise that I took off the large chainring before remembering to take a photo. Still, all was not lost, it turns out their were two chainrings on my bike (though I, of course, only operate in the ‘big ring’).
Behold, a photo of my small ring:
Continuing the embarrassingly grimey theme, it appears my chain rings were in competition with the rear derailleur jockey wheels to see how much gunk they could hide about their person (or actually in plain sight).
So, with the chain rings off, I’d exhausted the list of items I was comfortable taking off the bike frame that I was also (reasonably) confident I could reattach.
I couldn’t see a particular need to remove either of the derailleurs entirely, and I didn’t plan to touch the brakes. These could all wait for a later date (when perhaps I’d accrued a little more mechanical acumen).
Cleaning The Bike Frame (And Reassembling The Drivetrain)
So it was finally time to give the frame (and the components still attached) a good clean. Which is what it (and they) got:
Reattaching the chain rings. Turned out to be pretty straightforward. I put some grease on the threads of each of the bolts because, you know, that’s what us pro mechanics like to do.
Interestingly (or not), after claiming to have given the frame a ‘good clean’, I can see a bit of dried on mud at the bottom of what I think is the seat post.
Still, it looks pretty shiney in this shot, right?
It took me a disturbingly long time to work out how to re-thread the chain around the jockey wheels of the rear derailleur. It’s almost as if I’d never seen a bike before… In the end I went ‘old school’ and consulted my
Once I managed it (reattaching the chain) I took a number of photos, just to savour the moment (and to record for posterity the one time in 2017 when my bike was really clean…).
In the photo below, the eagle-eyed amongst you might note the front derailleur is Ultegra, whereas the rest of the gears (and the brakes) are 105 (and old-fashioned ‘5700’ 10-speed 105 at that).
The elephant-memoried may recall that I upgraded the front derailleur when I managed to knacker the 105 version in the middle of last year.
I’m pleased to report that the Ultegra front derailleur is still in good nick (it certainly doesn’t have the same scuffage as the 105 kit).
Cleaning The Wheels, Cassette and Re-greasing My Speedplay Pedals (Abridged)
… And lo, the day of bike cleaning became a long one. And it was good.
And long. So I won’t bore you with too many more details.
I cleaned the wheels, including degreasing and scrubbing out gunk from the cassette. I must admit that I didn’t take the cassette apart though. I just got down and dirty with a brush (formerly resident in our kitchen sink).
Maybe we’ll save deep-cleaning the cassette for another post (ooh, the anticipation…).
Meanwhile, I’ve dealt with removing and replacing the grease inside Speedplay pedals before, so I won’t go over old ground. For the avoidance of doubt though, I squeezed in some clean fresh grease (into the pedals) and squeezed out some ol’ dirty brown muck. So to speak.
Measuring For Chain Stretch
A sensible person would have checked for chain wear before embarking on hours of cleaning. I decided to do it after removing the chain, cleaning the chain and reattaching the chain. As to my level of sense, you can draw your own conclusions.
It was actually quite exciting (I live a closeted existence). I haven’t used my chain measuring tool much (it’s this one from Park Tool – yes, Park Tool again…).
Essentially you stick one pin betwixt two outer plates – where the chain is wider – and the other movable pin into another chain link made with inner plates. You then push the V-shaped black lever until it stops and see what number can be seen through the little window to the scale beneath.
The reading of 0.25 (which I think means it is subject to 0.25% of wear) means that the chain is still usable. The time spent cleaning it wasn’t wasted!
For my 10-speed chain, if the checker had read 0.75%, I’d be in the market for a new chain (11-speeders would need to think about a new chain at 0.5%).
Incidentally, bike chains don’t actually stretch. It’s a misnomer. Just thought I’d throw that out there (without any further explanation…).
A Clean Start
So there we have it. My deep clean was completed. I successfully put the bike back together. It even worked when I tried to ride it – wonders will never cease…
If you don’t tend to take your bike apart in order to clean it, I hope this post has given you a little confidence that even the somewhat mechanically-inept are capable of doing it (and reassembling it afterwards).
The more experienced amongst you can laugh and point at all the mistakes I (unknowingly) made.
So, do you clean your bike on a regular basis? Do you find the process meditative or frustrating? Do you have any good tips to share? Let me know in the comments below.
