willy wonka Posted June 23, 2007 Report Share Posted June 23, 2007 (edited) Hi i was just wondering what techniques of grinding a rim is and what works the best!!! Please help and leave comments!! Thanks! jamie!Hi,The best way to grind a rim would be to use a angle grinder.You will need a metal grinding disc for the best results, although some swear by stone grinding discs.You will need your wheel out of your frame, with your tire off too. I'd put a cloth over the cassette now to protect it from the grinding shavings.If you want a deep grind hold the angle grinder at a steeper angle and if you want a lighter grind hold the grinder flatter.Also the amount of pressure determines the grind significantly. So more pressure means a deeper grind.Now turn on the angle grinder and skim it across the braking surface on the rim using the various techniques from above.The quicker you skim it across the sharper the grind.Make sure that you DON'T keep the grinder in the same place on the rim, it will eat through your rim very quickly.Make sure that you have gone over all of the braking surface and your done Clean up any metal shavings off your wheel to try and prevent punctures.

jsychem Posted June 23, 2007 Report Share Posted June 23, 2007 also, make sure you get some grind specific pads like rock blues Soft pads such as ZOO's will be dead within a week if used on a med+ grind Quote Link to comment Share on other sites More sharing options...

Up'n'away Posted June 23, 2007 Report Share Posted June 23, 2007 While this topic is here i might aswell ask if the Green Coust pads are ok on a medium grind(Coust-sinks)? Quote Link to comment Share on other sites More sharing options...

willy wonka Posted June 23, 2007 Report Share Posted June 23, 2007 (edited) No they tend to disintegrate on a grind.Don't know where you got that from but my friends couts where amazing on a grind.Lasted around 12 months too (on a medium but sharp grind).They are designed for a grind so I can't see why they would disintegrate.
