Re: Mark Cavendish TdF

good effort under adverse circumstances, that. Maybe he had some hope that the commissaires would take pity on him (there is a get-out clause for exceptional effort) but it was not to be. I wouldn't write him off altogether but for him to come back to stage-winning form (and in a team that will supp...

Re: 2018 Tour De France (Spoilers)

….Without G, Froomey would still have not been first, Dummoulin piping him on the line.... Without G, Froome would have sat on DuMoulin's wheel and (probably) outsprinted him at the finish line. As it was, Froome thought it more important not to lose a few more seconds to his team-mate, even if he ...

Re: Schwalbe One Problem?

brake track widths and brake block widths vary. In many cases it is necessary to adjust the height of the brake blocks (more than once) as they wear, which is rather annoying. Note also that the brake blocks are usually tapered in cross-section, making the applied brake block width wider as it wears...

Re: Why have disc brakes become so popular?

If there are so many people who claim (on this forum and in other places) that disc brakes are so wonderful, what was it that happened to suddenly make them available and/or popular? I take your point that they still are by no means universal but they seem to be spreading to more and more bikes. th...

Re: Schwalbe One Problem?

note also that the pivots for the two arms on a DP brake make the brake blocks swing in a way you might not expect; typically in a front brake the right brake block swings lower as it wears, but the left side brake block swings upwards and tyre damage arising is not at all unusual. The marks on your...

Re: Help! Threaded my left hand crank pedal threads

Helicoils were first made for imperial threads; they are not the only thread repair insert type however. Helicoils are spring-like and are slightly oversize in their free state, hence the winding in tool etc. However not all thread repair inserts are like this, some are solid, and can (with care, th...

Re: Why have disc brakes become so popular?

Just a gentle reminder that the thread was really asking why now? (though I accept that isn't clear from the thread title). Remember, they had over a hundred years to get their act together. A hundred years? -not really; the 'invention of the disc brake' a hundred years ago did not result in the wi...

Re: Why have disc brakes become so popular?

one is bound to enquire why it is that, if your wheels don't turn any more, you need brakes at all....?.... :wink:

Re: 11 speed cassette on DD3 hub

ought to work but might be limited by the clearance between the mech and the spokes; try first using an old cassette etc before investing in a load of new stuff, perhaps?

Re: Help! Threaded my left hand crank pedal threads

if the insert is the standard (spiral wound) type then it ought to be fitted using an appropriate tool, which is usually one with a slot that engages with a (snap-off) tang in the centre of the insert, like this; https://sites.google.com/site/kearnsbryan/HeliCoil_7.JPG This 'pulls' the insert from t...

Re: Why have disc brakes become so popular?

for many years posh Raleigh roadsters had stainless steel rims. These can (and do) wear out, and the wear isn't really visible until the surface breaks through. With other steel rims the chrome wears off and the rim rusts horribly well before it wears through.

Re: most valuable/missed tool loan

one is meant to take only tiny cut with each successive adjustment, so that binding does not occur, or can be powered through. On some tools the top adjusting nut can be released so that the reamer reduces in size and stops binding. There should be no need to wind the thing backwards, but nearly eve...

Re: Noises

another thing that can rattle more on a moulton is the chain and rear mech, if the suspension is moving much. Also some of the cable housing runs from the handlebars can be much longer than normal, so for example the one for the front brake can flap around and make noises too.

Re: Noises

on a separable moulton, check the cable connectors; they can rattle like crazy.
