Thanks folks. I will ponder whether it's worth the effort. I've worked in oil and it now spins freely but it's loose and noisy. However, chances are If I take the effort to fix it, the recipient will just leave it in the rain (again).

Hi,

I'm working on a single speed kids bike with a rusty and worn out freewheel on a 20" wheel. It's not for shifting easily. It's branded Tri-Diamond.

Has anyone any advice?

Thanks

I know there are thousands of happy users out there but I rode them through one winter and didn't like the way they handled. They never put me on the road but they made the bike feel vague and me nervous as I like a bit of feedback. I remember one particular club ride where we rode a couple of miles down a wet, leafy lane and I was totally ill at ease with the way the bike was behaving and was left way, way behind by everyone else.
I changed to Grand Prix, also from Continental and was astonished at the huge improvement.

I had a pair of Gatorskin Hardshell and they were as you describe. Riding in damp conditions made me very nervous.

I personally do not know what size of seat post for your bike, but if you live near a bicycle charity it would be well worth a visit. They usually have boxes of salvaged seat posts which can be had for a few £. That would be in keeping with a bike that only cost you £5,

I have TRP HY/RD calipers and I just turned my bike upside down to have a closer look. Without removing the caliper It's hard to see how the retaining ring comes off but my guess is that its screwed onto the lock knob (part 14 as shown on https://trpcycling.com/products/hy-rd-s ... 3142219039). The ring rotates when you turn the lock knob so my guess for a removal strategy would be to use a pointy thing to stop it turning while you rotate the lock knob. Good Luck!

+1 for Ron Hills. My default winter wear. As cyclop said "Cheap and last ages".

Does anyone know of a frame builder which fabricate handlebars to the customers specification?

In 1969 when the film Easy Rider was a thing, we got the local blacksmith to weld up some ape-hanger bars for us. Lets just say that the finish wasn't top quality (as in rubbish) and they were bl**dy awful to ride. They turned heads however, and that was the only thing we cared about.

We were living in Alexandria near Balloch on the southern shore of Loch Lomond.
I rode every working day the 14 miles each way to Clyde Submarine Base .............. no, I wasn't a submariner, but a technician working in the Communication Centre on the cryptography equipment.

Through Glen Fruin? If so a lovely though slightly challenging ride for twice a day.

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.

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.

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?

1987 Raleigh Royal 531ST, but I have had it from new.

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.
