JWright Posted April 30, 2009 Report Share Posted April 30, 2009 I bought my bike off eBay second hand and it had ground rims but I think they need re-doing. What is the best way to do it? Cheers Quote Link to comment Share on other sites More sharing options...
N.Wood Posted April 30, 2009 Report Share Posted April 30, 2009 Deflate the tyre but keep it on - Tyres have loads of oily shit on the insides and as soon as that goes on your rim, your brake is shit. So keep it on. Then watch this: Trials-Forum Video -> Full View • Download • Upload EDIT: AND you get to listen to Modest Mouse. bonus.

psycholist Posted April 30, 2009 Report Share Posted April 30, 2009 I clamp the wheel in a bench vise and let the grinding disk spin the wheel by holding it at a very slight angle to completely radial on the braking surface - very quick and very effective once you use a cutting disk. I also wear eye protection and heavy gloves - nothing like small lumps of aluminium moving at high speed into your body to ruin a perfectly good day...
