    Had my headset replaced recently by the LBS but the bike was returned in a not like-for-like condition. On the first ride back on it I couldn't quite work out why I felt so much higher up on the road, balance was slightly off and handlebars were squint. So arrived at my destination and had a look around the bike.

    Spotted the problem: the stem was on upside down. So en route to Edinburgh on the train I make the decision to correct it, despite thinking that it could be a fiddly job at the best of times never mind on a wobbly train full of sleepy grumpy sheep. Against my better judgement I get the headset cap off, loosen all the bolts, take off the bars, take off the stem, fork falls out, bolts fall all over the floor. Bike grease all over my hands. Exactly as feared. Nightmare. But 20 minutes later it's all back together. Very satisfying. Although there's always that niggling doubt in my mind that I've probably done something wrong (from previous experiences).

    Stem-slam nightmare! Best get that checked by a non-local bike shop in case you've lost a bit?

    Made it the 4 miles to work so I am safe in the immediate short term although agreed it needs to be checked by an experienced professional. Where's the Bike Dr when you need him or her.

    Dr Bike should make a safety check but not rectify a defective headset. Wonky steering would be a clear and present danger to the rider's safety.

    I'm working on the presumption that the headset was installed properly, it was just the stem and handlebar assembly that proved too much for the LBS. But now that you mention it, maybe I should get a second opinion on the whole thing... I mean how difficult can it be to attach a stem? It either sits correctly and flat or incorrectly and points towards the sky.

    It took me three attempts to thread the chain through the jockey pulleys correctly (which gave me good practice of chain breaking and rejoining), but I successfully managed to repair the broken chain of a fellow towpath cyclist this morning with my trusty, if seldom used, chain tool.

    I would work on the assumption that one mistake signals others.

    Some stems are designed to be invertible are they not? Possibly not this one by the sounds of it though.

    There is a stem-slamming culture amongst cycle couriers and other outlaw groups.

    Yesterday, my chain started slipping spontaneously, with no traction. I thought, oh no, will be new parts needed.

    Get off bike and inspect. Somehow a twig has wrapped itself the cogs where my chain is located. Removed twig - bike fixed! Not even oily fingers :) Champion

    @jdanielp

    This stem is Halford's finest cheapest stem so it's not invertible. Congratulations on your rescue this morning.

    I am after a super long stem 150mm - they are on trend but they will also work for me - long back wee legs

    Anyone want to swap?

    "Some stems are designed to be invertible are they not?

    Forum user druidh once posted about blithely inverting their stem to switch between cycling modes - pointing up for off-road and down for road or similar. As I have historically had shaped-beam lights and so on mounted to my stem I did not regard flipping or swapping a stem as something undertaken for any reason other than urgent repair or replacement.

    Not bike maintenance but definitely satisfying.

    18 emails fired off to various local councillors, MSPs, MP, Transport Scotland, Amey, BEAR Scotland and council workers to request some cycle lanes and pavements on a particularly horrible part of my route to work.

    Now I guess I sit back, relax and wait while every one of them either ignores me or tells me yes fantastic idea but [insert perceived insurmountable problem].

    Bike making 'vole in long grass' noises so took off the rear brake caliper this morning. One piston stuck so I unstuck it.

    Bicycle now quieter and considerably faster.

    @gembo I might have a spare that's coming close to that length - can have a wee look in the Box of Stems. If so it could come out on Balerno Tattie Day.

    Managed two involuntary back wheel skidz (are for kidz) this morning. Rear brake a sight more powerful with two functioning pistons.

    Old Dura Octalink crankset and BB bearings replaced with Ultegra Hollowtech 2 on summer bike. Pair of Dura Ace / Open Pro wheels fitted to winter bike. All items second hand from eBay.

    Finally got round to replacing a freehub body. Stopped ratcheting properly a while ago (been riding a different bike).

    Also had a broken spoke.

    Changing a freehub requires axle removal.

    Pleased to find lots of grease still working.

    So, not all CV bad...

    Had to replace THREE spokes!

    Got a bike with mudguards and pannier racks again!

    Very pleasing fudged DIY session. Had to replace the crown headset components on my Fuego recumbent which had become notched. It's happened twice in 7000 miles, perhaps something to do with the forward weight distribution of the lowracer format, and the fact I clatter the small front wheel over many a Borders cattle grid. Anybody that cycles down the old coach road to Stow knows the one at Brockhouses.....

    Happened to have an FSA headset which I had bought ages ago but never used. The cups are a different shape though. So I had neither the tool to extract the existing cup or the one to press the new one into place.

    A successful outcome was achieved using a large flat bladed screwdriver inside the steerer tube and tapping it out with a hammer, and then pressing the new one into place using nothing more technical than a small piece of wood placed flat underneath the new cup and tapping it in with the hammer.

    It is possible I hastened the demise of the previous headset when experimenting with different forks a few months ago - I forgot to put the cartridge bearing back in when putting the original fork back on and rode it for 200 yards wondering why the bike was trying to kill me. By the time I realised I had ground a gouge into the fork crown and no doubt messed up the headset parts. But that's the other thread....

    Hardly maintenance but took down Mrs Garto’s bike from its hook. Pumped tyres, lubed chain, adjusted front brake (not sure how that wore out hanging on a hook but guess both daughters used it a few times). Gave it a dust. Checked height of saddle was just below optimum. I think first few times it gets used to take Mrs G to hub school will be best if saddle is a little low.

    This is quite amazing news really for Gembo Towers.

    I guess as I am in lock down too, any issues can be quickly resolved twixt here and Juni Green

    A few weeks ago I thought a wee plasticky clatter on the road was connected to me, so stopped for a look and found the front bit of my mudguard had slipped or wobbled off. It slotted back in, but the other day I noted it starting to slide off again and starting to crack. As there's very little weight to the mudguard itself it might have been getting batted by the light, which can get a bit clattery on cobbobbles if it starts resonating, so it's had its first layer of epoxy added and shall have a second layer with some sort of patch tomorrow.

    @nobrakes

    You can make a decent bearing press with threaded rod, two bolts and a stack of big washers. I've done motorcycle head and wheel bearings that way.

    My cheap Aldi/Lidl double pannier now has bits of wood on the inside, braced by the existing hooks on the outside, to stop the rear corner bending towards and flapping against the spokes, with a wee bit of bungee through the hole at the end to keep the whole thing pulled forward (and the hooks engaged with the struts).

    Serviced one of these to help a single mum friend of ours to get her son cycling;

    Pretty robust bit of kit on its fifth teenage owner. Had to hammer the rim straight where 'someone' had gone over a kerb with the flat tyre I also fixed.

    I put new Continental 5000s on my new (to me) Shimano RS80s and went for a spin. A little bit more road buzz but much better round corners than the old RS80s. Those lasted eleven summers and they'll do for spares.

    I laced a new rim to my new hub yesterday. Took me four goes to get it right which speaks volumes about my mental state.

    I eventually did it by working it out from first principles, which is always a useful exercise for any task.

    I shall tension it and true it in the frame as best I can, which is another good thing about disc brakes - roughly round is still rideable.

    The old rim (that was struck by the bumper of a BMW last year) regained its true Pringle form when I cut the spokes out. Surprised the over-tensioned spokes holding it straight never snapped.
