TommyBrew Posted March 21, 2012 Report Share Posted March 21, 2012 Alright people Looking for a rear rim Upgrade at some point in the future. Currently running a echo 44mm rim that comes standard on the 12 Piranha. Compared to previous experience a few years ago when I used to ride, I'm not confident in this rims ability to hold a grind... They don't seem to last long and I've tried a couple of different pads. Looking to upgrade maybe to a trial tech either spot or Sl, any feedback?. Is there any particular gospel way to grind a rim, because mine brake always makes the Desired sound and lock when rolling backwards haha. Very frustrating. Either I've lost the Knack of it, Or my rims cheese . I can't seem to settle on a pad that I feel il stick to, but could be the rim or grind. I'm going to try a grind without removing the tyre or tube and see if that helps.. When i grind the disk is rotating away from the centre of the wheel if that makes sense, so the burr is on the outer edge. Any comments greatly appreciated as I'm still gathering long forgotten tips and tricks, Cheers guys Quote Link to comment Share on other sites More sharing options...

TommyBrew Posted March 22, 2012 Author Report Share Posted March 22, 2012 I think mines a tr not but standard on the piranha it's only 44mm wide . And no matter which way I grind, always works better backwards :@ Quote Link to comment Share on other sites More sharing options...
Greetings Posted March 22, 2012 Report Share Posted March 22, 2012 Well if the TR is only 44m wide, perhaps you should look at something like this 1 Quote Link to comment Share on other sites More sharing options...
Revolver Posted March 22, 2012 Report Share Posted March 22, 2012 I think mines a tr not but standard on the piranha it's only 44mm wide . And no matter which way I grind, always works better backwards :@ Going on the tartybikes brake setup video, you need to set up your brake better - it should make the same sound going both ways.

SamKidney Posted March 23, 2012 Report Share Posted March 23, 2012 TRs are among the best rims Ive used. Mine always held a grind really well. Make sure your using a new disc on your grinder. 45 degree angle, little pressure, fast sweeps over your rim. Perfect sharp medium grind that will last. Add LGMs and you'll be laughing. Insane braking power. Little tip to you guys.... chamfer your LGMs like the Beleay counterparts. They make them even better. Quote Link to comment Share on other sites More sharing options...
TommyBrew Posted March 23, 2012 Author Report Share Posted March 23, 2012 For some be green tnn pads to try. And will try a fresh grind with a new disk. Pads are always square which is why I'm stumped. I'm using an echo brake if that makes any difference?. I do recall the magura to be a bit less spongy though...

TommyBrew Posted March 24, 2012 Author Report Share Posted March 24, 2012 Got some new Tnn be green pads in on a harsh grind with a new disc, and left the tyre on the rim to reduce contamination. Works a treat =DI also chamfered them like you said, what does this exactly do? Quote Link to comment Share on other sites More sharing options...
