I did quickly look at the rim to see if there was any sort of wear indicator on the Matrix 750 rims but I couldn’t see anything and so either there wasn’t a wear indicator or potentially more worrying the wear indicator was worn off a long time ago, if for example it was a line around the rim. I don’t have any tools to assess the rim wear but I’m going to read up when I can and do the best that I can to check it. If the rim seems fine then I’ll go ahead and order all of the parts above and give it a go myself.
You might want to check to see if your Matrix 750 looks like that in the pic below, if so it should have a wear indicator groove unless it is completely worn off, and it should also be easy to measure and compare the width in relation to 22.2mm.

I know that the idea of dynamo lights are a bit like marmite and lots of people have perfectly good arguments both for and against. However given the winter commuting that I do I’d like to try dynamo lights just so as I don’t have the constant task of charging batteries & lights.
Now only because I know that dynamo lights seem to be more popular / readily available in Germany than over here I started my search on the Rose Bikes website and they had this:-

If the link doesn’t work it’s the following for £112 plus postage.
It is indeed a slippery slope, so if I were you I would check the width of the rim(s) and its condition carefully more regularly if you decide to patch it up and carry on riding it. As you have already discovered it is easy to spend close to £200 on just some parts, especially if you want dynamo hub wheels. However, as I mentioned up thread you can often get a reasonable new bike, with full warranty, for less, especially when you consider that your existing bike, whether patched up or in bits, is still worth something in the secondhand market.
