Re: Hub Dynamo-DIY Voltage regulator questions

It is interesting that this works for you. In the 1970s, when dynamo sets were sold without regulators, the inevitable result of the headlamp bulb blowing was that the output voltage would rise, due to the much lower current drain of the rear lamp, and the rear lamp would blow shortly afterwards. Ar...

Re: Dynamo bulbs

Pay attention to the manufacturer's remarks about external regulators, which seem to get more insistent as you go down the page.

Re: 27" Tyres

For the narrower tyre I know of three 28-630 on sale in the UK at the moment: Continental Supersport Plus and Ultrasport (The Supersport being the more expensive with protective belt.) Pasela Tourguard folding (Rather expensive in my view, and requires a hooked rim.) Variously from SJS and others. L...

Re: IGH lubrication; a smoking gun.

In the UK the ubiquitous SA three speed gear was fitted with an oil port for about 80 years or so. In exchange for the slight effort required to add a few drops of oil through the hole once a month, an SA three speed gear could reasonably be expected to last a lifetime of commuting or pottering abo...

Re: Cycling into the River/Canal

....., towpaths are never going to be a cycle expressway due to poor surfaces and sharing with dog walkers anglers et al. Enjoy them for what they are - ... Probably the best summary of the whole discussion, and a succinct description of all UK cycle facilities since the dawn of time, except that m...

Re: Cycling to Axbridge from Bristol

If you are arriving at Temple Meads you could take a local train to Nailsea, which cuts out all the fiddly bits trying to find your way through the docks and suburban sprawl. Depends largely whether you want a ride in the country or to see Bristol's somewhat tatty industrial archaelogy, or any other...

Re: Advice/Info Please on *another* Dawes Galaxy

"The rear wheel looks like it needs a true for a start so that will be a job for the LBS." If the rear wheel is merely somewhat out of true, rather than buckled, then gentle experiments with a spoke key might save a lot of expense, and give you a wheel that is round, and fits the bicycle ...

Re: Advice/Info Please on *another* Dawes Galaxy

We have a small fleet of similar tourer's from that decade, all but one having been in the family since new. I would not replace or add anything unless it is worn out or you want something different. These were fun to ride when they were new, and are still fun to ride. Most components from that era ...

Re: Does anyone know.... about 27x11/4" Tyres

What is likely they will be eventually available only in 32mm, there is only one 28mm listed. In the long term probably, but there are actually two 28-630 listed, one being disguised as marked only by 27 inch, which covers two widths. Surprisingly this one actually came onto the market about two ye...

Re: Spares for France

The tyres had been tested with the rims concerned, which are hooked. Proceeding from discovering that a 10 mm axle could be used in place of a 9.5 mm to proposing that all axles are interchangeable at the cup/ball interface probably was rather a sweeping judgement, although I prefer to think of it a...

Re: Spares for France

Thank you for all the comments, I think I shall offer the axle, but not be too concerned if the offer is declined. A little further research shows that the part can be bought online in France (1), in fact seems to be part of a range including the current longer lengths. Being a little old fashioned ...

Spares for France

One of the children is about to depart for a short cycle camping tour of Brittany on a Claud Butler dating from 1980, which is in daily use, something she has done several times before. As usual, I have drawn a 27 inch (28-630) folding spare tyre from store ready for issue, to cover the probability ...
