delusional Posted May 24, 2005 Report Share Posted May 24, 2005 Sorry, there may be a deluge of posts from me over the next few days. New bike, lots of of new mechanics to play with, lots of things I don't know! Anyway, I have a Tioga Factory DH rim (the ones with the white stripe) that I'd like to put a light grind on. However, around the outside edge of the rim is a small lip that I'm really going to have to grind off to get to the sidewalls. A small test shows it'll come off fairly easily, but I'm being a bit squeamish about grinding some of the shape of the rim away like this. I'm pretty sure it's not going to weaken the rim any more than grinding does anyway, but I've got doubts in my mind now that I'd like to have allayed by those in the know. Any advice?

Tartridge Posted May 24, 2005 Report Share Posted May 24, 2005 The lip is 'extra' to the sidewall... so removing it isnt gonna make any difference (Y) (compared to a 'normal' rim) Quote Link to comment Share on other sites More sharing options...
the666ers Posted May 24, 2005 Report Share Posted May 24, 2005 I did it without a second thought, it's just tioga trying to be clever about pinch flat prevention. It's fine without it for sure, mine are still dead straight. Just go carefully and they'll be great. A grind lasts a while on the rear too, but if you drag your front brake a lot it'll wear off fairly soon. My ultra fine grind wore off in 2 months on the front. But is still perfect on the back.

dave33 Posted May 25, 2005 Report Share Posted May 25, 2005 try not to grind that lip off as it stops pinch flats make loads of difference as i found on a mavic disc rim i ground was great think it was a f219 Quote Link to comment Share on other sites More sharing options...
delusional Posted May 25, 2005 Author Report Share Posted May 25, 2005 try not to grind that lip off as it stops pinch flats make loads of difference as i found on a mavic disc rim i ground was great think it was a f219 Too late now :) I've already filed it off one side of the rim ready for grinding (or sanding, not sure which yet)! Went with using a file in the end because the small patch I ground off didn't seem to be coming off that smoothly. I was concerned it was taking too much off the inside edge of the rim at the same time, as I couldn't quite hold the grinder smooth enough to grind just the lip (it kept dipping and catching the inside edge at an awkward angle). It takes a little while longer with a file, but at least I'm happy I'm not wrecking my rim! Quote Link to comment Share on other sites More sharing options...

hititfaster Posted May 25, 2005 Report Share Posted May 25, 2005 Hey Dan, you should be ok to take that lip off. Ashton was (/is... I'm not sure) running those rims in 26" and he ground them, so I'm sure you'll be fine (Y) I take it everything is in order? Quote Link to comment Share on other sites More sharing options...

I picked up on that snippet while hunting around for info on this, it probably should have confirmed for me that it was safe, but once you get a seed of doubt like that a direct answer is much more comforting. Everything's great :) Really enjoying riding the bike, although I've begun to hate evo mounts. I'm sure I'll get the hang of setting them up properly soon though, it just involves hours of fiddling at the moment! Quote Link to comment Share on other sites More sharing options...
