I genuinely don't understand why more people don't do this kind of thing; it isn't very difficult and it is win-win-win all the way.

On a similar point. I do not understand why anybody needs a bike shop to maintain their bikes?
A bike is a hobby and a hobby needs to be worked at.
My opinion of course, I do not want bike shop owners upset.
I think bike shops are for selling bikes and repairing bikes for young family types. Not older grown up enthusiasts.
I have a 'bike shop'. near where I live.
I have been into the shop a few times. Ask for a tyre for a Brompton? Never heard of a Brompton! Asked for a wheel to be built with a dynamo hub. He told me that dynamo hubs were not made any longer and were on old bikes! Asked for a set of brake shoes for cantilever brakes. Told V brakes are used now and cantilevers were obsolete!
Not been there since.
What I cannot understand, is that I moved from where I live now, to Dorset for about 9 or so years. I moved back here 5 years ago and the shop is still in business with the same owner! How come?

It depends on whether your hobby is riding + fettling, or simply riding. I'm happy with the former, but it's not for everyone.

Bikes are just a tool and a form of transport

‘Going cycling’ is a hobby or a sport depending how you do it.

Generally people who do the former have little interest in the workings of the tool, where as those who do the latter *may* also take an interest in the equipment, but plenty (majority?) don’t.

The former greatly outweigh the latter, hence... bike shops.

The latter are geeky and invested in their hobby, hence... forums and tips like these threads.

I’m in the latter group, but most of the people I ride with can’t even tell you how many sprockets are in their cassette let alone the ratios etc. Maybe I’m doing it wrong, maybe they are, but we all have fun.

I think you have this the wrong way round.

Really? It’s been my general experience that the vast majority of people who use bikes for transport and simply as a bike aren’t normally that invested in the details of how they work.

Where as those who are into it as a hobby or sport are more likely to be the ones who get into the equipment as well.

Only my experience, others may have different viewpoints of course.

I agree with the above, exceptions like myself excluded as I do both :D
Time spent riding usually means greater experience and inclination towards fixing. Occasional 1 mile commuters are not the same as 20 miles each way daily types. The latter know how to fix their bikes. Old timers fix their bikes, internet spawned newcomers don't .
All generalisations of course. :lol:

Re the 7 speed freehubs mentioned above. Are we talking about bog standard 7 speed, say Deore/XT type things. I have a heap of them as I never chuck anything work (and rarely anything that doesn't work) . Assuming they fit on to the hub, they work then?

yes if they fit to the hubshell they can be made to work. However the RH locknut/cone assy needs to be made shorter if you are fitting it to an 8s hub, the seals need to be compatible and of course spacers are moved to the LHS of the axle.

Also if you want to go the final mile, the shoulder on the LHS of a 7s freehub body is slightly wider than on an 8s freehub body, which can lose you 1mm of dish vs a modified 7s freehub body. Machining back the shoulder isn't the easiest thing in the world to do.

Another route is to shorten an 8s freehub body. However if you do this the splines run to the end of the body (so no 11T sprocket, but you didn't want one of those anyway...?). The limiting factor can be the lockring threads in the end of the freehub body; basically you can run out of threads if you are not careful.
In most cases an 8s body can be shortened such that various 7s and other shortened cassettes can be fitted provided a 1mm spacer is used between the smallest sprocket and the lockring. This is about as thick a spacer as can be used before the chain is spaced away from the dropout in top gear, (because the lockring will interfere with it otherwise.)

A word of caution; if you put a wheel of this sort into a bike which previously had a standard wheel in it, and forget to adjust the derailleur accordingly, the first time you go for bottom gear it won't end at all well.

Worth a play then. Have an equally large box of 7 speed axles etc and for once I actually labelled them to match the hubs,cones etc.
I have ground 10 speed hubs to fit 11speed cassettes a few times so that's a go as well.
Got a nice 8 speed Campag groupset triple that worked well on my disc braked , Shimano wheeled set. Improving the hub/wheel etc would be something to go at.

Does anyone know whether the same holds for 11s GRX and 11s campagnolo shifters as hopds for 10s. I think that it will but I'm getting confused!

Having just bought some 11 speed Athena "B" shifters and rereading this I took to measuring cable pull (not attached to anything) and get a pull of 2.6 per click (ignoring 11 to 10) which lines up with the Shimergo tables. I am now confused enough to just buy the correct mechs!

Good used or NOS Shimano 10-speed stuff (105 upwards) is often more expensive than new 11-speed. A lot of people have expensive wheels, shifters and mechs and really don't want to spend thousands replacing most of their bike for one extra cog.

Shimano had to break compatibility because 10 speed was already at the limit of robustness for the existing pull ratio, but no-one really needed the extra cog in the first place. Road riders now expect massive rear sprockets, I suppose. 30 years ago, a 23T was considered wussy.

Thirty years ago, cycling was even more riddled with macho stupidity than nowadays!

Too right. 13-20 was common for hills. It's a real change of attitude. What's particularly odd is that really wide gears make sense on a do-everything bike that's used for racing and more relaxed riding. But bikes have got more specialised, not less, so there should be no demand for wide gears for bikes used for racing on the flat.

A 13-21T cassette does look really, really cool, though.
