Earl Posted June 4, 2009 Report Share Posted June 4, 2009 Just wondering why grind your rims?I have been riding for some years now and never grind-ed my rims yet what are the pro's and con's. Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted June 4, 2009 Report Share Posted June 4, 2009 You grind you rims for better brake performance because there is more friction between pad and rim because of the rough surface.Pros:Better brakeBetter in the wetBetter biteCons:Your damaging the rim (in a way)Pads dont last as long.

Sprog! Posted June 4, 2009 Report Share Posted June 4, 2009 bad points: .slowly makes the rim weaker, if you do harsh grinds.wears down your pads faster.people would pay more for a non grinded rimgood points:.better noise.better hold.better biteALTOGETHER I'd say give your rim a grind but before you do what pads are you running?

I am ze best Posted June 4, 2009 Report Share Posted June 4, 2009 Plus some pads don't last as long so dont use weak pads. Quote Link to comment Share on other sites More sharing options...

Use hard compounded pads like phatpads, koxx bloxx's on deep/harsh grinds. And magura blacks etc on smooth. Quote Link to comment Share on other sites More sharing options...

But not as good as my double koxx bloxx combo. Quote Link to comment Share on other sites More sharing options...

a.l.3.x.13@hotmail.com Posted June 4, 2009 Report Share Posted June 4, 2009 The reason why people grind their rims is so the Hs33 brakes get better traction (friction) thtas the pro's i dont think that there are any cons hope thats helped.

I have never had problems yet still using them in all three bikes except my Czar I'm testing some Plazmatic's in the back for the first time.

Dan Thornton Posted June 5, 2009 Report Share Posted June 5, 2009 Ive just gone to a medium grind with try-all croco yellows.I can already say mine feels alot better than the smooth rim setup i used to run.Dan. Quote Link to comment Share on other sites More sharing options...
MikeWarner Posted June 5, 2009 Report Share Posted June 5, 2009 I don't get it either. The most friction possible is between two very flat surfaces. Grinds reduce the surface area, so surely the braking performance is worse. It just doesn't make sense to me. Quote Link to comment Share on other sites More sharing options...

entersandeman Posted June 8, 2009 Report Share Posted June 8, 2009 Basically mate its really a personal preference , grinding your rim's is a cheap way of drastically improving your braking , the pads will hold better as it gives them more to grip on to . A lightly grinded rim with a lit-tle tar is my personal choice . it also depends on the pads you run with, Tartybikes give information on each pad they sell ,this includes what the pads would be best ran with . pads I’ve ran in the past include - Rockpad Blues - i found that these were an all round good pad . - Snowies - when run with a smooth rim are dang good . - Try-all croco browns - good pads with unbelievable life .By the sounds of it you have your heart set on running smooth rims , in which case go for snowies ! Hope this helps ! Brock Quote Link to comment Share on other sites More sharing options...
