Re: Singlespeed chain & freewheel- what am I missing

you can see the grooves in this picture; not every 16T freewheel has them but plenty do

even with the grooves not every chain will work

Re: Peugeot with Reynolds 531 frame tubes ( info sought )

yours has the metal head badge; I was saying the PR10E in the brochure image above doesn't have the metal head badge .

So what do the stickers on your hubs say?

What size seat pin fits? -was it 26.6mm or some other size?

Re: Rear derailleur with a difference; lets call it 'Blinky'

this picture (from Disraeli gears) http://www.disraeligears.co.uk/Site/00_Thumbnails/Japanese_Patent_S60-261788_thumbnail.jpg shows that there is a leetle problemette; at first sight it looks as if the cage could swing further backwards and keep the chain tensioned. However if it swings much further...

Re: Rear derailleur with a difference; lets call it 'Blinky'

Looks are highly subjective; it can't be a look that everyone loves else they would have sold gazillions of the things. As a practical proposition, unless my eyeballs deceive me, there is a significant issue with these mechs; the third pulley appears to be a 9T one. Good luck trying to find another ...

Re: Rear derailleur with a difference; lets call it 'Blinky'

still have not seen one in the flesh, but found more pictures including of a model called LePree http://www.velobase.com/CompImages/RDerailleur/6F47447A-A8D8-48B8-A1F0-AC8B231B80A2.jpeg which appears to be a close relative of 'XC' otherwise and indeed Cyclone MkII with the same cage on it too (altho...

Re: Tektro R539 compatible with old or new levers?

AFAICT R539 calipers are the 'new pull ratio', which Shimano referred to as 'New Super SLR' (which I have usually abbreviated to NSSLR) when they launched it in 2008. They (and others) have referred to it in various different ways since, including 'Super SLR' and just 'SLR', but neither term can pos...

Re: Wide range 'period correct' Campagnolo gearing

Note the wear on the top edge of the inner cage plate - frequent close encounters with the freewheel. An illustration of CJ's point about the top spring, perhaps? I reckon. I guess when you have a side plate which stands up like that, it can maybe touch the neighbouring sprocket if the intervals be...

Re: Singlespeed chain & freewheel- what am I missing

16T freewheels are often built on the largest possible sized body which means that not every chain will fit; some of them will have side plates which are too tall and prevent the rollers from hitting the valley in each tooth. You can buy 1/8" chains which are bushingless and these are shallower...

Re: The perfect cable lube.

the synthetic oil I use is synthetic gear oil. If I were a cleverer chap I could tell you what it is and whether it is an ester type. PAO. or PAG type oil or not and what the name of the oil is. However I long ago decanted the remnants into a smaller bottle and that knowledge is lost in the mists of...

Re: Strong front wicker basket for Pashley Roadster- any suggestions?

If you want to take the basket on and off quickly then a support which mounts on the down tube (and doesn't turn with the steering of course) on a QD bracket would be the thing. However this bracket is rather pricey and (as mentioned above) can cause trouble with any tall loads because you won't be ...

Re: Tightening spokes on one side of a wheel

FWIW that is an excellent diagnostic tool but on many bikes the disc has to come off the wheel because it will otherwise clash with the RH chainstay.

Re: Repairing inner tube punctures

Good question! If there ARE still tubes available that don't have this irritation, then they seem a much better solution than carrying razor blades or just buying more hard-to-repair tubes. It's funny what people will say rather than admit that they can't answer the question :P it is almost an impo...

Re: Frameset transplant: Spa Titanium Touring

…. It's the rear mech cable outer which is about an inch too long. I re-used the cable outer from the donor frame and just put it on as it was, in a bit of a rush. I knew I would be re-visiting that later on. I looked at the photo and for me, it was a toss-up between that and that the rack appears ...
