BROMPTON INGENUITY From Alan Bradley, Belfast I wonder if any readers would be interested in some ideas and suggestions for the Brompton? I think a fitted Scottoiler would be a great factory option for the Brompton. To avoid running the oil pipe past the folding points up to the handlebars, the reservoir could remain in the rear triangle and its top-up action could be done manually – or perhaps even operated automatically upon folding, with a manual way to disable this if you fold the bike a lot. The Brompton BWR hub gear (see Issue 31, page 7) looks very good. In a wider axle form it might be useful for ordinary commuter bikes, which could use double 42-52 chainrings to get the same interleaved ratios as the Brompton. I wonder whether they added an oil port, like on old hubs? I can see the point of grease-filling hubs as a protection against people who never oil them, but as grease dries out, and oil is superior, an oil port would be useful. A fully-enclosed (but easily separated) chain case for a
derailleur does not seem impossible to me. Could some design students not develop one as a project? Do Brompton get a copy of Velo Vision, incidentally?
Yes, Brompton (and most other manufacturers featured in the magazine), do receive a complimentary copy – whether they get time to read it is another matter!
LOCK IDEA From John Prince, Isle of Man Whilst on holiday recently in Normandy, France, I came across this brace of Bromptons. The locks fitted to the frames, which appear to be the standard Dutch item normally fitted to lock the rear wheel, appear to have several functions. Used as photographed the connecting chain goes from lock to lock (and in this case around the post). Also, I think that when the Brompton is normally parked with the rear wheel folded under, the lock would hold this captive. The only suspect area appears to be the clamping, using normal nuts and bolts which could be removed. Perhaps Brompton might perfect this idea and offer it as an option?

TSR QUERY From Dave Swindells, UK I am a subscriber to your excellent magazine and remember you running a review of the TSR8 shortly after it was introduced about three years ago [in issue 21 –Ed]. Rather than going for the new Brompton 6 with the wide-ratio Sturmey Archer gearing which they are soon to produce, I am thinking of the Pashley Moulton TSR8 model instead, although haven’t finally decided. Have you any comments to make on the durability/ general quality of Pashley Moultons? In particular, I am not familiar with the Sturmey Archer Phoenix hub gear mentioned on the Pashley Moulton website and wanted to check that its a reliable model. I also noted the gear range of the TSR8 is rather high, i.e. 33" to 99". Presumably if I did order one they could supply a smaller chainwheel to drop down the gears overall? Apologies for asking lots of questions but at least I know you won’t have any financial gain to make from this and so any comments you can make will be impartial/objective. Thanks in anticipation.

First of all, the bike itself is fine to the best of my knowledge, although a very different machine to the Brompton as I’m sure you’re aware. And I would see no problem with dropping the ratios – with the 20" wheels I doubt you’ll start to hit hub gear limits. Moulton, or their dealers, will no doubt be able to confirm. As to the hub gear, the ‘Phoenix’ is actually just another name for the 8-speed Sunrace Sturmey-Archer XRF-8. There have been mixed reports. Certainly the early batches were very hit and miss, and even some newer ones seem to have been rather temperamental and require rather precise cable adjustment. But they are otherwise OK, and actually rather good if the cable is just right! Sturmey also introduced a new shifter a little while ago which apparently improved matters noticeably. But as you may have read in Issue 31, p.34, a new version is on the way with slightly wider range and, they say, a less sensitive cable mechanism. But I’m not sure when this will hit the market, and more specifically, when it might start being built into TSRs. You’d have to check that with Pashley direct. If you’re playing it safe, it might be prudent to wait for the new version of the hub to ‘settle in’ for a while, too.
