Could it have been Clarks? If
Could it have been Clarks? If it was you definitely did the right thing.
I’d guess the bung is
I’d guess the bung is slipping up inside the steerer causing the bearing preload to be reduced. Check the manufacturers specs for the torque setting on the bung – I’ve seen carbon steerers wrecked due to over tightening. And be aware that running a loose headset on a carbon steerer can cause a groove to be worn on the steerer making it unsafe.
I have 4700 running on a 105
I have 4700 running on a 105 chainset and its shifts nicely.
The way I set up an FD is:
Chain on small ring on front and big on back.
Back off FD cable tension and adjust low limit screw so chain just stops rubbing on the FD.
Add some tension back so that you can shift to the big ring.
Shift to the the big ring ensuring that you have used all of the lever travel i.e you are not in the big ring trim position.
Shift to small on the back.
Adjust the FD H limit screw so that the FD clears the chain. This needs a little more clearance than the L setting.
Click the shifter into the trim position and shift to big on the back. Adjust cable tension until the FD is not rubbing.
Shift down to the small ring ensuring you pass the trim position and check that the first trim position allows for small – small with no rub.
Hope that helps.

Not sure I have selected the correct sizes and models for you but you can obviously do a more relevant comparison if needs be.
The difference is a cyclist
The difference is a cyclist who views “German SUV” owners as a group will be wary of them with no power to intimidate or endanger them. A “German SUV” owner who views cyclists as a collective can be terrifying and dangerous.
Appreciate most of your
Appreciate most of your content Ashley – that I’ve seen. You’re desire to educate people to correct and allow for other people’s mistakes and bad driving is great. I do however feel it fails when the stakes are a bit higher and the actions of others threaten physical injury or death. We’ll see how you feel or react when someone deliberately tries to scare you, or run you off the road when you are out and about on your bike.
The only real gripe I have with your content is it makes no effort to address the notion that cyclists are responsible for the behaviour of all other cyclists and we have some kind of collective responsibility. This view is prevalent on much dashcam content on YouTube. A 15 minute collection of road incidents primarily featuring motorists, with one stupid cyclist, and it’s the cyclist element that gets the comments ‘bloody cyclists’ etc etc. There are no ‘bloody motorists’ comments that assign a similar group responsibility despite motorists featuring in the vast majority of clips. This mentality is allowed to perpetuate and cyclists get ‘punished’ because some other cyclist did something stupid somewhere else at some other time.
When in small/small with the
When in small/small with the chain all slack, if you physically push the derailleur back, does it go back into it’s normal position with the chain held in tension? If so, and assuming the derailleur is mounted correctly (bottom lug against the mech hanger lug) and all tight, and the mech hanger tight, then it’s likely dirt or corrosion in the derailleur pivot. I’ve seen it a few times but usually on old kit that has suffered a few winters with no TLC and not on the newer style Shimano derailleurs (front ones are a different story – seen plenty on the newer style ones all gummed up and sticky). The pivot can be stripped and cleaned.
If the chain only goes slack when the wheel is spinning without the pedals being spun, is there a spoke protector dragging on the cassette?
The motorcycle comparison is
The motorcycle comparison is interesting. I used to do lots of track days too but would never have considered going out on the track in anything but leathers and full face helmet; I would have rode very different in a t shirt and jeans. I definitely undertook riskier behaviour due to the reassurance provided by the PPE but the actual risk of injury and death was significantly reduced by the PPE. So where the risk of injury and death is actually reduced by the risk reduction measures then it doesn’t really matter if people change their behaviour. When it does matter is when the actual risk isn’t reduced – just people’s perception – and then the risk increases.

Do they have removable valve cores? If so, are they tight?

I tried 32 tooth on a short cage Tiagra and although it vaguely worked, it definitely wasn’t happy. Changed to the proper long cage and no issues.Same here. I think the frame geometry/mech hanger set up has a significant impact – what works on one bike may not work on a different make or model.
If it clicks when climbing
If it clicks when climbing then it might be worth checking the headset is correctly tensioned, and that the stem bolts and saddle clamp bolts are tight.
Do you have matching wheels?
Do you have matching wheels as some wheels brake better than others? My summer wheels brake really well but my winter wheels on the same calipers, pads and cables are a bit meh in comparison.
Uberbike do some nice
Uberbike do some nice threaded bottom brackets which can be serviced and the bearings can be replaced if required.
I use a good waterproof grease to keep the weather out which helps bearing life.
I disagree that few drivers
I disagree that few drivers are out and about for enjoyment. I’d say a significant proportion are but for most it’s the destination that is to provide the enjoyment/entertainment rather than the actual journey. Result is the same. A further significant proportion are driving not because they have to, but simply because it’s convenient for them – short journeys that could easily be walked or cycled are an obvious example.
Rather than feeling selfish for impacting motorists by cycling, consider the impact of using a car on everyone else – the risk of accidents resulting in serious injury or death, pollution which is estimated to kill about 40,000 in the UK annually, congestion, impact on the environment and wildlife etc. I don’t feel selfish when I cycle but on the odd occasion I drive I do.
