I've had several pairs of touring wheels from Spa Cycles and they've all been good.

Five years have whizzed by, but for various reasons it is only now that I have repeated my experiment of replacing a chain without replacing the sprockets, now using the current technology of cassettes and bushingless chains. I had a chain that was less than 0.2% worn at 2200 miles, but when I check...

When you took the old cable out, was there any sign of damage close to the nipple, e.g. fraying?

depends what sort it is...?

cheers

True! I'd forgotten about the other sort.

A 'wear indicator' is either a wear non-indicator or a non-wear indicator.

I have been trying to visualise what happens if you use two BB cup removal tools, with one in the vice and a spanner applied to the other. I think things start to come apart somewhere, but I might be missing something.

4603 does use a larger bcd for the inner ring than 5703. As Tompsk says, 30t is the smallest that would fit Agreed. See https://www.sjscycles.co.uk/chainrings/shimano-tiagra-fc4603-92mm-bcd-5-arm-inner-chainring-d-type-silver-30t/ . There's not much metal between the bolt holes and the teeth. It wo...

I have a Chameleon but have never ridden a Joey so cannot compare. One difference which may matter to you is that there is a much wider range of tyre sizes available for the Joey than the Chameleon.

I think it's digital. Don't you have to use fingers to turn the knobs?

You should be able to see whether there is any significant structural damage, eg by flexing the tyre and peering into the cut. What the structure looks like can usually be found on the internet, e.g. cross-sections of different models of tyre from the likes of Schwalbe and Continental. For example, ...

I am very happy with my Hewitt Cheviot SE off-the-peg tourer. It does not have the caché or fancy lugs of my Roberts or Mercian, but it rides beautifully. The Roberts has a bit of toe overlap and the Mercian chain stays are a bit short; the Hewitt is better in both respects - it is longer, of course...

They need to be bright because bikes are not expected to have them. I once was about to overtake a bike when at the last second I realised it had a dim RH indicator flashing. The rider had not looked behind.

Quite right. 1/2 inch difference in circumference => 12.7mm/2pi = 2.02mm difference in radius.

I wondered that, too. SJS cycles list 590 and 597, two widely used sizes in that era.

See also the Cycling UK guide (based on CJ's much earlier CTC web-page) - 590 and 597, but no 594.

I believe that it's conventional at this point to refer to The Zen Shim Question: http://www.hilarygallo.com/the-zen-shim-question/ Thank you for relieving me of the need ever to find out what that book is all about :roll: I found 'that book' fascinating, one of the few I have read three times. It ...
