I have a 1982 Mercian, which had a Regina 5-speed freewheel and double chainwheel until 2010, when the block fell to bits. The rear dropouts were 122mm or thereabouts.
I had the stays opened out by a frame builder to 130mm to take a modern wheel, which it did perfectly. However, the chainwheels will no longer line up satisfactorily with an 8-speed cassette. On the outer rear sprockets, the chain line is so far out that it eventually pulled a side plate off the chain.

I’ve bought an anatomical saddle after years riding on Brooks leather ones. It is comfortable but lacks eyes under the seat to support a saddlebag. I want these bag loops.

Double-leg cycle kick stand
I am looking for a strong, stable but lightweight double-leg cycle stand. Can you recommend one?

Is there a technique for setting the Shimano derailleur gears found on mountain bikes? With constant use, these gears often start to miss a cog or will not go in at all. I’m struggling to adjust them as I do not know which screw is which. Could they not be different colours?

I have a Batribike 20 tricycle but am struggling to apply the rear brake effectively due to tenosynovitis in my left hand. This rarely causes trouble, except that I now live halfway up a steep hill and need to brake my trike fairly forcibly. In the last month, I have ridden the trike a lot in Holland where I had no trouble at all. Have you any helpful ideas?

Are there any shaft-drive bicycles on the market today? I know several types were developed and sold in the 1890s and 1900s.

On page 20 of the Oct/Nov issue of Cycle magazine, reference is made to mountain bike gearing ‘with a narrow-wide chainring’. I have not come across this phrase before. Can you explain?

Diabetes and energy drinks
I’ve just had my annual blood tests done. The result was a slight impairment of glucose regulation. This did not show diabetes but could increase the risk in the future. This got me thinking about the energy drink I use (SIS Go Energy). Is this okay or should I consider changing? I don’t go hard and fast on my rides, generally a steady 50 miles at around 12.5mph.
