Is It A Good Idea To Grind Your Rim?

[amj onza]

I've got an onza T-mag and I find that I'm always having to put tar on the rim to make it sharper! So will grinding the rim, really make a big difference, and improve it's peformance?

[Krisboats]

Generally yes, depending on pads, and how you grind it.

allows the pads to stick to the rim without movement

I wunt suggest grinding rims anymore, i used to run a grind, but they just wear down quick and you end up giving it a new one every couple of week.

Id suggest buying sum smooth rim pads, like zoo's or echo's, and just use a bit of tar.

Hope i helped, danny

I feel that it depends on what rim you have as some rims keep they're grind and some don't. I have a echo 2007 rear rim and I ground that a few weeks ago, thats kept its grind really well and was a medium to sharp grind. My mates try-all rim has slightly worn down now and we ground it at the same time.

Tar isn't that good, and once you put a grind on a rim , you'll notice a definite change.Also tar isn't good in the hot sun.The pads have a habbit of sticking to the rim.

get a grind!

to be honest, without grinding i still kill rims, with grinds, the sidewalls just dent rather than my wheel ending in a big mess on the floor

grinds work in the wet tar doesnt it makes your brake worse

do it

I also have a Onza T-mag with a grinded rim and it has really improved the grip of my break. When running a rim with a grind you have to have a decent set of hard pads or they will be gone before you no it. At the moment i am running plazmatic crm pads (which i would really recommend) with some tar and it gives me amazing breaking.

Grinding is good if you have the correct type of pads.

And don't make the grind too deep, or you will damage the rim eventually after doing it again and again.

when i grind my rims i do a very very light grind on it

but i dont do it often and my rims are pretty much smooth again at the moment.

Oh for god sake! just wack the biggest grind on your can! get a decent set of pads, (im running rimjams) and just run it, if your brake decides not to work half way though a ride just put a dabb of tar on.. it dont make too much difference to the rim... well it does! but what would you prefer doing, grinding your rim every-week and wasting your time and still eat away the sidewall - or put a deeper grind on and have a quality brake for a few months?

get a grind and some rock blues and your break will be sweet. however if you dont want to run a grind, then get smooth rim pads. but i would strongly reccomend a grind, as my brake has never slipped after i ground my rim. hope iv helped

[ryan360]

It would be alot better than just a plain rim but i think putting tar on rims is a lot sharper than a grind.

[adamant_a2]

hey. my break was terrible with a grind and the red rock pads (they were supposed to be the same compound as blues according to tarty, but wrong die was used) and it was terrible. i put a light grind on and some plazmatic crm's and my brake is a monster and makes such a nice squeak with an immense bte. do it with crm's. u no u want to. ope this helps

[Concussion]

I say stick with tar, its quick and easy to apply. Balls to all that grinding your rim/pads don't work/what grinding disk/wheel collapse bullshit. To name but a few!

...shit in the rain though, but meh`

I once rode a non ground rim in the wet and broke my elbow. Yes, grinding your rear rim is very good.
