Grinds On A Wheel

[Callum Trialsin]

Like the title says how many grinds do you do on your wheel before you get the rim replaced.

Or is it just done on how it looks.

thanks

Callum

lots

and lots

Ill NEVER change a rim cos ive ground it too much, itll die before that happends.

[Sam Nugent]

Depends which rim you have, how heavily you grind it and how heavily you ride it...

I have never had a ground rim myself so don't know sorry.

tll die before that happends.

ye, cos its been ground so much..

[Davetrials]

no grinds dont affect rims that much, takes alot of grinds to do summet like that

[Pauly]

usually about 15 before my rim starts to fall apart

I'd say 20 to 25. If your asking because you wanna grind your rim but don't want it to die, don't be worried, it barely botheres the rim.

Bit off topic but might save another thread - is there a way that you should grind the rims surley it will be a better grind one way round?????

[Dan6061]

Surely it depends on the rim?

Surely it depends on the rim?

yeah i thought that cos rims are made from different materials But i don't think it affects the result that much

I dunno how many it took, but in a period over about a year and a half, my Ronnie had paper thin sidewalls.

You'll know when it's on it's way out 'cos it'll dent t'fook and then the dents will crack along the apex of the fold.

Then the metal will break off.

Then you'll die.

no i mean if the rim spins ---> that way

then will a clockwise ----> or anticlock wise <---- grinding action get you better results

because someone said on a ride the other day my brake works better backwards i think i did the grind the wrong way round i didnt really understand but im grinding my new rim tommorow tommorow so just wanted to check

Or just stop bouncing and jump/fall off. Andy manged to destroy his sidewall on tuesday and it wasn't really anything impressive... he'd been doing hefty rolling gaps for the best part of the afternoon and must have just hit it exactly on the dent that was already there. He just seemed to get off the bike look at it and then before you could say "jack robinson" he was on the phone to tarty sorting out a new one.

My rims had about 12 grinds on it.. However my grinding technique is very light and is about 1/4 of the normal grind destruction. When it happens it happens, just ride it till it goes.

EDIT: If you grind you're rim clockwise on both sides then they are both ground in opposite directions kind of so it'll give you a braking surface thats good for both forwards and backwards hold.

i'm guessing thats how a grind looks close up so depending on which way you drag it.

i do quite savage grinds, so my mast ronnie has lasted about 10 before the sidewall folded over and cracked.
