Disc brakes - wheres the magic?

[Piernas Flacas]

I think is a matter of preference. I prefer Vs, but then again, I've never tried discs  Having said that and after reading some of the reasons why one should have discs I have the following comments:

 

- A wheel would really need to be badly buckled, or rather tacoed, to interfere with V-brake operation, which in any case could be disconnected or readjusted, unless the wheel can't even rotate. Therefore, a wheel with discs would also be useless, not so?

- I've heard discs that squeal like fire engines when wet

- If discs have such stopping power, why are they not used in road bikes? We know the speeds that can be achieved on the road and they also ride on wet conditions.

on the road question, i think weight is the issue. i remember seeing some commuter-type (essentially road frames with flat bars) bikes equipped with discs. the squaling can be a pain, but it's not that hard to stop it. a coupla weeks back i destroyed the front wheel of a fellow hubber's bike there was no way in hell that the brakes could be re-adjusted to nurse the car back to the groenies parking lot. but i swopped out my disc-shod wheel - luckily a dual-purpose wtb wheel - and put it on her bike so she could continue riding.

Howzit, B! Hope you're well. Then, according to your answers, stopping power is not a problem with non-disc brakes, and secondly, how did you ride back at groenies? That was very generous of you

hey piernas! yeah, i'm great...you? when we gonna ride again? wasn't generous, i'd taco-ed her wheel quite badly and felt very guilty. it wasn't the easiest ride back - i'd fractured my arm - but my eldest son was the hero. he insisted on riding back to the paking lot with me. we removed the bolts of the disc caliper on my bike and zip-tied it to the fork but out of the way of the spokes of her wheel. it rubbed a little against the fork, but wasn't too bad.

 

i think the stopping power comes into it when you start talking really fast speeds. at barberton a coupla years back, on the long downhill, i ripped a v-brake arms right off the front wheel. it coulda been ugly if it got caught in the spokes!

1. not true. a wheel that is even slightly buckled touches the brake pads causing unnecessary friction - slowing you down!

 

this is no problem on a disc rim.

 

 

 

2. not really, but if it does, never more than a wet rim brake.

 

and usually a wet rim also has mud, sand and oil on it making for REALLY interesting sounds.

 

ie. this is the sound of sand getting ground into the rim.

 

ie. this is the sound of not stopping because my pads are aquaplaning on the rim surface.

 

 

 

discs generate so much heat that they dry themselves within miliseconds anyway.

 

 

 

3. weight

 

 

 

 

 

geez, for all you guys who think v-brakes cannot be replaced by discs - it's like saying the light bulb would never replace the candle, or the car would never replace horse drawn cart.

 

 

 

try discs, and you'll understand
