Re: Tyre/wheel sizes

Yes, rubbery worms, some smooth, some knobbly. Yes, as Brucey says. In addition, there is a table of not-too-uncommon tyre sizes and their multifarious markings at https://www.cyclinguk.org/cyclists-library/components/wheels-tyres/tyre-sizes , but note that some entries like 13/8 should be read as 1...

Re: Wobbly Bike

A wheel can be thought of as having five components: 1) an axle, which should be securely held in the cycle frame; 2) the rest of the hub; 3) a rim; 4) spokes connecting rim to hub; and 5) tyre and tube. Any of these can be responsible for wobbliness. If there was no wobble before you changed the ty...

Re: Initialisms

I think some dictionaries are starting to include the 'wrong' meaning of the word acronym, because it is so widespread. Without acronym we wouldn't have bacronym… cheers No, they aren't wrong, dictionaries themselves change with popular use/acceptance in modern language, thus they are correct in ch...

Re: Initialisms

STD used to mean something to do with telephones, now it is a nasty itch. Whereas std, often means standard. That STD has now morphed to STI, which is still a nasty itch .... to, er, spend money on handlebar bling? TLA = three-letter abbreviation , BTW. The 'onym' of acronym comes from the Greek fo...

Re: Front light positition

The headtube is not a good idea because in generations past riders routinely used capes in the rain, some still do, and in other countries it is common amongst utility riders. it would also preclude the use of bar bags or wicker baskets for example. Perhaps this is why it used to be common on conti...

Re: Chainsets

That is pretty much what I have on my Roberts: 40t chainwheel aligned with cassette centre, 24t inner ring, 11-34t cassette. It works. I use outer ring on 13t to 30t sprockets most of the time.

Re: Sturmey Archer AW & Styria hub gears

... Are there specific parts that you need? Thanks, Brucey, but no parts needed at the moment. It worked fine during minimal testing (a couple of miles). Judging by the general state of the back wheel it has been subjected to too much oil rather than too little. So all I plan to do is fit a larger ...

Re: Sturmey Archer AW & Styria hub gears

I am cleaning up a Jack Hateley bike I have just bought on ebay and was amazed to find, when I removed all the clag, that the rear hub is not Sturmey-Archer but 'Styria' made in Austria. The indirect gears are 3:4 and 4:3. Maybe '69' is the year of manufacture.

Re: Where is this?

... But if we step to one side on Streetview and look to the north (roughly) there are trees on top of low hills. They are more distant looking than ideal for an easy match, but could that be the wide angle nature of Streetview? https://www.google.com/maps/@53.2729476,-3.3079371,3a,37.5y,118.93h,84...

Re: Where is this?

In the original photo you can see an intervening low ridge partly obscuring the hill-top trees towards the right. Looking at the 1:25000 OS map and in particular at the contours, this could only happen looking at this hill: singing_kettle_view_SE_720p.jpg - Streetview, looking south-east from the Ll...

Re: Gain Ratio?

Many years ago the CTC Handbook contained a specification for a touring bike, including a normal gear (expressed in inches as usual for the UK) of ten times crank length, a top gear of twelve times crank length and a bottom gear of five times crank length. This is one way of expressing the fact that...

Re: English Language - what "Does your head in" ??

Does anyone else find the word 'sabbatical' ridiculously pretentious? In Scotland we call it a 'brek', as in 'tak a brek'... The word 'sabbatical' has a precise meaning - a year off taken every seven years. It is often used slightly imprecisely, acceptably, but when it used completely imprecisely, ...
