edd91 Posted January 21, 2009 Report Share Posted January 21, 2009 Well as it says whats the difference between the two rotors i can find out, and its seems to be more expensive for a floating rotor. Quote Link to comment Share on other sites More sharing options...

N.Wood Posted January 21, 2009 Report Share Posted January 21, 2009 Fixed rotors - One piece steel rotor, what 99% of all disks use.Floating rotors - Two piece design comprising of an aluminium spider or centre section with a steel braking surface bolted to it.Floating rotors tend to be lighter due to the aluminium carrier in the middle, and aids heat dissipation.

edd91 Posted January 21, 2009 Author Report Share Posted January 21, 2009 (edited) Well i was just looking at the tech m4 and thought what the hell never heard of that, them http://www.hopegb.com/mes_r_typ_s_rayonche...icherche_1.htmlEdit: Thanks Edited January 21, 2009 by edd91 Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted January 21, 2009 Report Share Posted January 21, 2009 Unless you like knocking noises steer clear of them for trials. Quote Link to comment Share on other sites More sharing options...
edd91 Posted January 21, 2009 Author Report Share Posted January 21, 2009 What the rotor or the brake? Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted January 21, 2009 Report Share Posted January 21, 2009 Floating rotors, after a while they develop quite a bit of play. Totally fine for what they are made for though, just not trials. Quote Link to comment Share on other sites More sharing options...
psycholist Posted January 21, 2009 Report Share Posted January 21, 2009 (edited) The rear disk on my hardtail is gone pretty rattly and that doesn't get trialsed - just a few backhops the odd time ... Officially floating calipers allow the rim of the disk to expand relative to the disk spider for high temperature use (It reduces the chance of the disk warping). Shimano/Magura disks are riveted to the spider and so aren't really floating disks, but they get rattly just the same if they're used on the back...

ogre Posted January 21, 2009 Report Share Posted January 21, 2009 theres a video floating around of some mode rider gapping to front with one of them floating rotors and it sheared off on all the alloy bits he was fine but it's not worth the weight saving/bling for increased risk of failure.

Ashley-Wood Posted January 22, 2009 Report Share Posted January 22, 2009 Floating rotors, after a while they develop quite a bit of play. Totally fine for what they are made for though, just not trials.my mates seem perfectly fine and hes running a 203 on a mod soo basically his brake is sharp as and he has no play at all,also its way better than his old normal rotor. and hes had it for a while. seem find to me if they are set up correctly.

Simpson Posted January 24, 2009 Report Share Posted January 24, 2009 my mates seem perfectly fine and hes running a 203 on a mod soo basically his brake is sharp as and he has no play at all,also its way better than his old normal rotor. and hes had it for a while. seem find to me if they are set up correctly.Hardly a fair test? A 203 on a mod is stupid anyway, and so will offer too much power weather or not its a floating rotor! Quote Link to comment Share on other sites More sharing options...
