wayneone Posted December 31, 2005 Report Share Posted December 31, 2005 Hello everyone,I was quite bored last night and my mind began to wonder what is the best form of braking Rim or disk?Now im not asking how to get good brakes so no "get a grind" or "get some good pads" ect, No what i want to know is which one technicaly is better? Is it better to stop a wheel from the rim or the hub?At first thoughts i belived it to be the rim due do it being far away from the hub which is where the wheel spins from giving more leverage, But then i thought but if the wheel stops from where it starts this will give the better stopper or will it? So after being puzzled for a while i decided to come on here and pick your brains on the subject.Discuss... Quote Link to comment Share on other sites More sharing options...
deanie-b Posted December 31, 2005 Report Share Posted December 31, 2005 A friend called Don, An aussie I'm not sure whether this is even right, But that due to the distance from the hub The circumfrence makes the same power as a rotor would I.E 26 Inch wheel rim brake = 26" Rotor20 inch wheel disc=20" rotorAs you probably know, Most disc brake companies don't go any higher that an 8/9 inch rotor.

petit_pablo Posted December 31, 2005 Report Share Posted December 31, 2005 In theory a rim brake should be the better due to the extra leverage.However, disks can have larger surface areas and bigger callipers. Plus, external factors (ie, dirt, water etc) mean a disk is probably the stronger push bike brake Quote Link to comment Share on other sites More sharing options...
mtbjosh Posted January 1, 2006 Report Share Posted January 1, 2006 but in nearly every case, if you have a go on a bike with a decent disk on the the front, it will out perform a rim brake every time no matter what the weather will be or how well its set up, in my opinion anyway. although you can set up v brakes to be pretty kick ass. especially an XT one , haha Quote Link to comment Share on other sites More sharing options...
Onza Kieron Posted January 2, 2006 Report Share Posted January 2, 2006 Disc's can work better simply because they have a different pad ratio, Thats what makes a RB lever more powerful that a normal Maggie lever as the piston is a mm smaller in the lever. If you fit a hope Lever to a magura, which you can't due to fluid... The the magura would be more powerful than a standard lever. Quote Link to comment Share on other sites More sharing options...
YAJIB Posted January 2, 2006 Report Share Posted January 2, 2006 yes i agree with onza keiron that is technically true and also i ran a disk brake then changed to a rim brake and that was twice as good Quote Link to comment Share on other sites More sharing options...
Wright Pads Posted January 3, 2006 Report Share Posted January 3, 2006 If you fit a hope Lever to a magura, which you can't due to fluid...

adamtrials Posted January 3, 2006 Report Share Posted January 3, 2006 Another thing that i dont thnk anyone in this thread has mentioned is that with stoppingat the hub there is flex in the spokes, meaning that rim brakes should be better as they have direct contact with the tyre. But at the end of the day, disks are still ace! Quote Link to comment Share on other sites More sharing options...
