Dai the Socket Posted September 19, 2005 Report Share Posted September 19, 2005 Angle grinder with Grinding or Cutting disk on. Wack your wheel from your frame, go around with it spinning at an angle, leaving a slight indentation. Loads of lines and grooves. Pads grip to them = improved braking in wet and generally a better brake. :) Quote Link to comment Share on other sites More sharing options...

Pads grip to them = improved braking in wet and generally a better brake. :) And if you want that in english, it translates to be.... Run around the side wall of your rim with an angle grinder. This will roughen the side wall causing there to be more friction with the brake pads, in turn giving better braking. Quote Link to comment Share on other sites More sharing options...

Zoo_Monkey Posted September 19, 2005 Report Share Posted September 19, 2005 just afew quick extras there are different types of grind - light and heavy some pads work better with light grinds some better with heavy, equaly some suck with a light grind and some wear down so quick with a heavy grind they only las 1-2 rides, the pic of the rim above is a heavy grind also before you butcher your rim you need to consider grind direction ie, the lines "drawn" buy the cutting/grinding disk should apose the braking action - check the pic (Y) best to get someone who has some experience to do it for you the first time hope that helps Quote Link to comment Share on other sites More sharing options...

Mark W Posted September 20, 2005 Report Share Posted September 20, 2005 A-ha, yeah. What he's done in knurled the rim surface. Similar to the above. You can machine the knurling onto it, if you or someone you know is good enough. I don't really know how long they last, although that looks fairly deep/well done, so it might last longer than a grind. Bet it *eats* pads though...

Siders77 Posted September 20, 2005 Report Share Posted September 20, 2005 I thought Onza were going to do it but didn't because when it was tested it ate pads up too fast? Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 20, 2005 Report Share Posted September 20, 2005 Nah. They machined circles into the rim (so it was like a grind, only more consistent), but the brake only held one way (Y)\ Quote Link to comment Share on other sites More sharing options...
Siders77 Posted September 20, 2005 Report Share Posted September 20, 2005 Ah right, that's what I must have been thinking of then. That's the one. (Y) Quote Link to comment Share on other sites More sharing options...
