Re: Would it be unreasonable … ?

Frankly I took do not appreciate being blinded by other cyclists. Perhaps the solution would be for organisations like Cycling UK to lobby government for new cycle light regulations, ones that copy the German legislation that specifies beam pattern. I only use German designed & built lights and they cast a bright beam pattern only on the ground and hardly any scatter into the vision of oncoming cyclists, pedestrians or drivers. I am less keen of the German requirement for dynamo for any bike over 11kg.

Re: Bottom bracket size

I agree with fastpeddler, you should be fine with perhaps a few tweaks to the mech. One of my bikes (for reasons) I am running 1.5 mm off the optimal chain line with no issues.

Re: Bottom bracket size

It's clearly a 68mm bottom bracket shell, as expected, and will almost certainly be British threaded. Bottom brackets of this sort are sold in various lengths which effectively control how far the tapered ends stick out. The length you need is dependent on the crankset you are using. If you know the model of the crankset you can try to look this up (hopefully).

Perhaps someone else with a similar bike can suggest the length?

Re: Cateye cycle speedo/computer adds stealth miles overnight?

I posted this a few years ago about my Cateye Speedo stopping working temporarily while cycling past the Skelton Transmitting Station. You might find some of the replies about radio/magnetic interference interesting

My thinking about energy use?
I agree that we will need nuclear energy for the foreseeable future - at least until the problem of storing renewable energy is solved.
I'm afraid that position doesn't consider the storage issue or nuclear waste and arguably the issue of of renewable energy storage is well on the way to being solved. It isn't quite there yet but the rate of technology progress in battery storage far exceeds the build time of a nuclear power plant, so what is the point of the latter?

For example, a recent news report from Scotland
"Each site [battery] will have the capacity to power around 800,000 homes in Scotland, for up to two hours, when required"
https://www.heraldscotland.com/business ... bles-boom/

(My note: Scotland only has 2.5 million home thus these 3 batteries alone can power them for nearly 2 hours)

Safer, much cheaper, much faster to build. What's not to like?

On mine about 5-6cm depending on where you measure, but 5cm below the lowest part of the weld.

Councillors have voted to immediately pull out of talks over the siting of a nuclear waste disposal facility in East Yorkshire.

Nuclear Waste Services (NWS) had identified South Holderness as a potential area for a Geological Disposal Facility (GDF).

East Riding of Yorkshire Council said it had listened to the public and decided to withdraw.

NWS said it would now "wind down" the South Holderness proposal.

The proposal to pull out of the talks had been put forward by two Conservative councillors, Lyn Healing and Sean McMaster, and was voted through almost unanimously at a full council meeting on Wednesday.

Beverley and Holderness MP, Graham Stuart, said he was "delighted" at the result of the vote.

In the UK we have had nuclear power for the last 60 years but not one gram of high level waste has yet been legally and safely placed in a long term (safe?) repository. The reasons are many fold, but geological and engineering issues are huge, but nothing in comparison to the political issues. It will be a bold political who finally decides on a locality.

I find it astonishing that we are currently building another nuclear power plant with no idea where the waste products will go, just a hope that in the long term "it will be all right". Talk about unjoined up thinking. I am well aware that modern plants will produce much less high level waste but all the same repositories will be looking at keeping material safe for timescales of a few 1000 years. A nice legacy to leave our descendents.
Indeed. I know a poor sap in the Civil Service who spent years blessed with the job of with getting the long term underground store built. Location found and technical issues largely sorted but from the look of it the whole thing is just too hot to handle politically.

And it's not just Sellafield. A few years ago there were some truly terrifying reports of the recklessness with which all sorts of mixed waste has been dumped in a hole in the ground at the much more remote and secretive Dounreay site. Out of sight out of mind.

Hinckley C's cost is way more than renewables, and Sizewell C looks to be back in favour even though it would be on soft geology unlike the previous reactors there and closer to sea level. Both sites look to be at risk now we know the Greenland ice sheet will melt and Larsen ice shelf is at risk. The current flood risk around the sites is here:
https://check-long-term-flood-risk.service.gov.uk/map

Is it any wonder that the mental health of young people is deteriorating?
Interesting about your friend in the Civil Service. I am a retired geologist but around the time I was graduating in the early 1980's there was quite a push from the government to explore for onshore nuclear repository sites. Areas of low lying crystalline rocks were then the preferred target. This meant that significant areas of Scotland such as the Outer Hebrides were being considered. I remember going on a geological field trip to Harris and being met with extreme suspicion by the locals as being a possible harbinger of a dump site on their island.

I then remember that the kick-back from local communities forced a government rethink and surprise, surprise, the subsurface of Sellafield became the government's preferred dump site due to a degree of local "nuclear buy-in". Subsequent geological investigation proved its unsuitability. As far as I know, the UK still has no advanced plans for repository site or a repository method. Yes, there are options but no government will bite the bullet and make a decision. Interestingly there is a fair case for putting nuclear waste deep below the London area in a formation known as the London Clay. Now that would take the biscuit for political unsuitability.

Re: Sellafield

The issue of nuclear waste disposal is one of the prime reasons why we should not be using and developing nuclear power.

In the UK we have had nuclear power for the last 60 years but not one gram of high level waste has yet been legally and safely placed in a long term (safe?) repository. The reasons are many fold, but geological and engineering issues are huge, but nothing in comparison to the political issues. It will be a bold political who finally decides on a locality.

Nuclear power? It's indeed "No Thank-You".

PS, the rapid decrease in costs for renewable energy generation and battery storage should kill the economic case for nuclear power but hey, politicians and their contracts.........................................

I don;t think just tapping the frame woudl be enough, see the example photo below for how the holes for the bolts are typically reinforced in this instance.

That way of fixing isn't particularly robust. Here is what happened to the excentric BB my friend's Thorn. He did find a frame builder to reweld it however.

This probably isn't helpful, but such books used to exist. Here is a link to a post I made about such a book called Beginners Guide to Bicycling & Bike Mechanics. The illustrations very much bring to mind my experiences of keeping my bike going as a kid.

Yes, mine became a bit baggy. If I were to buy again I would buy one size down.
When you say baggy - The whole garment? Including the waistband?
The whole garment went a bit baggy for me, When brand new they seemed fine but on wearing everything stretched a bit. It might be however,that I was between sizes. I bought an L when I should have bought an M.

Re: Breaking spokes on new e-bike - how many is too many?

Could your problem be aluminium nipples? I note from this site https://www.cube.eu/uk-en/cube-stereo-h ... bad521261d that Cube Stereo 160 use Newmen Performance 30 wheels. Investigating these wheels suggests that at least some are built using aluminium nipples https://www.bike-discount.de/en/newmen- ... ront-wheel.

I have limited experience of aluminium nipples, apart from a friend who had to have her wheels rebuilt, but they are "Not recommended for hardcore use, as aluminium nipples are not strong as regular brass".
