Re: [RBW] Really not too off topic: disk brake question
Truing rotors can be pretty difficult. Before attempting to true a rotor, always make sure that the mounting bolts are properly tightened. I've also found that this stuff works well for getting rid of flutter: http://www.gravelbike.com/?p=1177 On Thu, Aug 9, 2012 at 6:15 PM, Jim Mather mather...@gmail.com wrote: Park actually makes a rotor truing tool: http://www.parktool.com/product/rotor-truing-fork-dt-2 And a Youtube how to: http://www.youtube.com/watch?v=nHdQkm14JVw jim m wc ca On Thu, Aug 9, 2012 at 3:35 PM, Peter Morgano uscpeter11...@gmail.com wrote: I had a smiliar problem on a Giant Traverse (I know, I know) that used to be my around town ride.

Re: [RBW] Really not too off topic: disk brake question
Thanks; must look at those bolts. And I'll remember Squeal Out if a rotor starts squealing. Maybe I'll remove the rotor, place it on a metal slab, and beat the hell out of it. It will make me feel good, even if it does no good to the rotor. I'm glad I no longer have 185s or whatever -- more chance of bending. That -- bending -- is the sole liability of disks, at least mechanical ones (I've not used hydraulics). I used to shove wheels in the back of the car, or else sling them up against a wall and this front rotor has paid the price before I realized I had to be careful. Also they don't modulate as well as my goodest calipers (single pivots -- old SunTour S Pro? -- with worn in Kool stops are as good as any dual pivot I've used, and modulate better) or nice wide profile cantis but otherwise they are very nice for fast wheel swaps and not worrying about grinding down expensive rims during sand riding and no g-dum housing hangars, balky QR mechs, and such.
