Just Wondering Why Grind Your Rims?


Earl

Recommended Posts

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 rim

good points:

.better noise

.better hold

.better bite

ALTOGETHER I'd say give your rim a grind but before you do what pads are you running?

You grind you rims for better brake performance because there is more friction between pad and rim because of the rough surface.

Pros:

Better brake

Better in the wet

Better bite

Cons:

Your damaging the rim (in a way)

Pads dont last as long.

I have never had a problem before so if what you say is right my brakes will still work anyway in wet and dry so why grind.

Magura blacks are utterly useless a i have used them for some time and done some big gaps with them. 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.

They are utterly useless. Yet you have had any problems with them?

My front black pads are ok and my plazmatic's are ok too so nothing as yet to report they are working fine.

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.

Rub sand paper against your face and test the friction then (Y)

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 !
