Re: Why have disc brakes become so popular?

There is a flaw in claim of those who insist that in a panic situation, a person just grabs a handful of brake lever. In many cases of panic (blind panic so called) people often FREEZE, and are capable of doing nothing at all. No thought, no automatic grabbing of brake levers in those few seconds of...

Re: Why have disc brakes become so popular?

Yes, well, I apologise to Brucey and , and will belt up (for a while. :oops: ) We all have strong points of view -that's life!

Re: Why have disc brakes become so popular?

I take your point (XAP)Bob and I reacted badly, but I'm not without experience of life. At 80 years old I have been, and still am, active in cycling?windsurfing/ surfing/kayaking and in the course of these activities I've had two near drownings (one I was hospitalised and only just saved) and severa...

Re: Why have disc brakes become so popular?

And you sir are verging on being a nuisance in that you will not accept the blindingly obvious. I do not assume that there is no better way than mine, I simply DO NOT CARE! Cease trying to tell me what I should do. It's my life and I live it MY way. Your continuing insistence that I couldn't cope in...

Re: Why have disc brakes become so popular?

Nice analysis Amediasatex, sir. Agree, and prefer similar feel. (Currently using Formula on two of my M.T.B.'s -not the greatest, but nice, and didn't break the bank.) I'm not into bothering to do scientific testing Brucey. I ride by feel. If it feels right, that's fine by me, and any nasty surprise...

Re: Why have disc brakes become so popular?

With regard to doing a 'stoppie', i.e. hurling yourself over the bars inadvertantly or otherwise. Many cyclists like to experiment, especially when young. It comes with the territory of being 'scared of nowt' as a show off teen, and balancing in silly situations on two wheels. (in the presence of gi...

Re: Why have disc brakes become so popular?

Stopper/stoppie, an obvious careless typo with words of similar sound, but your perverse and persistently repeated mantra is perfectly clear to me; that a bike which is unable to generate the force necessary to put one over the bars is safer in an emergency situation than one which can. ( You should...

Re: Why have disc brakes become so popular?

''Terminally arrogant.'

' Doesn't really understand the nature of the problem.'

'Simply have brakes that CANNOT GENERATE ENOUGH TORQUE FOR A STOPPER,'

Really!!! What's the old saying about having put yourself in a hole, stop digging!

Re: Why have disc brakes become so popular?

Yes, you could do as you suggest Mick, but you don't get maximum retardation with a locked wheel. For that, the flexible tyre needs to 'lock' into the rough road surface (think rack and pinion effect) just at the point of slipping. That would give the shortest stopping distance, but it requires a ve...

Re: Why have disc brakes become so popular?

Well I despair when people insist on misinterpreting what I am 'on' about! I am musing on the ultimate (disc braked) stopping G force which could be generated in the quoted ideal test conditions, by a skilled 'trick' rider, on a lightweight (in comparison to motor cars and motor cycles) cycle. Safet...

Re: Why have disc brakes become so popular?

Good on 'yer' Mick - but what would the shortest stopping distance be from 30 m.p.h., and G force generated, using a modern disc braked bike (mountain or road) with high hysteresis tyres (normal motor cycle wear) over an anti skid high friction 'Shell Grip' road surface as now laid in many danger sp...

Re: Why have disc brakes become so popular?

The 1 G maximum (i.e. minimum stopping distance from, say, 30 m.p.h.) braking deceleration has long since been beaten by many cars and motor cycles, in dry conditions over coarse grippy road surfaces. (The gearing effect and front wheel weight transference down force.) A Vincent Rapide 1,000cc motor...

Re: what has happened to Wiggle ?

Precisely! The last three sets they sent me, which I've carefully planted and watered ( pre-used bath water, of course) have shown not the slightest sign of sprouting into anything at all. They are deader than that mythical parrot! An instruction book of at least a thousand pages, as with my latest ...

Re: Why have disc brakes become so popular?

'.....one does an emergency stop. Can't remember ever doing one for real.' Well, there are situations which are beyond a persons ability to control. My delving into curious court cases (bedtime reading :roll: ) unearthed a rather extreme example which even put the presiding judge into a tizzy. An el...

Re: Why have disc brakes become so popular?

It appears that the argument against disc brakes on bikes has now taken a subtle twist into Alice in Wonderland territory, by claiming that they are only an apparent, as opposed to a real, safety improvement! In adverse road conditions ( greasy winter wetness, gravel washouts, snow or ice patches, G...
