Ground Rims ?!?!?

[WIGAN ??]

right after using smooth for about 2 years i made the mistake of grinding my rim, evry time i ride someones bike with a grind the brake feels really snappy and bitey so i gave into the temptation to grind it, iv gone through 3 sets of pads in about 8 weeks and dont even ride that often anymore and the brake has never been as good as my tnns on smooth, just wtf is going on help please ?

Grinds are brilliant. Just buy some heatsink yellows cnc backings and give it a new, good bleed (if its hs33 you have...)

could be to rough?

[josh barker]

what pads are you running Adam?

as said some cnc heatsink yellows or cnc rockpads. on a light/medium grind.

[WIGAN ??]

iv used tnn yellows,lasted about a week, rock blues lasted about 3 and i have koxx browns on at the moment wich are wearing down rapidly and will probably be gone in the next 3 rides all in cnc backs aswell, i wasnt expexting the yellows to last a lifetime iv been using a fairly harsh sharp grind on the blues and the browns and it just makes a sort of swooshing sound like its just powdering the pads and not biting them, a mate of mine who uses grinds has done my rim for me a few times and even he cant get it right and his brakes amazing :\

use a cutting disc for a light grind. works best for me

[Cahill Trials Kid]

could it be something to do with the rim you useing ?

[WIGAN ??]

probably not its an echo urban, its really weird cos my front vee is amzing on a grind and the pads barely wear down

f**k off, heatsink yellows on a harsh, well anything other than light grind is silly. They wear instantly!

You've got one hell of a harsh grind there Wigan! The Tnn Yellows are a very soft pad material as it is, as are the Hs Yellows.

Get yourself the Tnn Kbs, you'll never look back man! x

the yellows are long gone hha and i wasnt gunna get heatsinks anyway theyr pretty much the same compund, i was either gunna get some bealays or phats but im worried my grinds just gunna powder them and its gunna be a waste of money again, im not really pressing the grinder on hard and its at about a 45 degree angle iv followed all the steps on the tarty blog thing and NOTHING seems to be working, now i remember why iv hated grinds for all these years :|

Adam blud, I was in the same position. Just get the TNN's kenny belaey's with a fresh grind, no tar using a brand new stone cutting disc. f**king brill man.

I'm new to trials biking and i've seen all this talk on grinding your rim. What is a ground rim ?? and what does it do ???

[WIGAN ??]

basically gives your rim a rough edge and creates more surface area and is supposed to make your brake more bitey and hold better but so far iv had nothing but problems with them and still do, going back to smooth soon balls to grinds

Iv been using Monty 219XHs on a light grind there medium/soft and are lasting me pretty well...... So far.

Sounds like youve ground too harsh man like josh said you get a nice light grind with a metal cutting blade. Stone grinding blades are much rougher so you have to be much more careful

Its all about starting light, if thats not good enough try a bit deeper you can always grind more this way. If you go in for the deep grind straight away your pretty f**ked if its too harsh...

Grinds are good but a smooth rim can be just as bitey with some brake spray or fruit juice or genrally something that drys sticky like coca cola . i use a smoth rim and rockman blues and if i didnt have dry coca cola on my rim theyd be hopeless. but with coca cola stand up to the grip of most grinds

i hope this helps

Well im worried that my pads aren't wearing enough haha. i use a medium grind with heatsink reds in cnc backings and they have been on my bike for a year and there still loads life left!!

Mine are the 08 heatsinks still going strong! and my brake couldn't actually be better. I would say go for some heatsink pads and they will last ages!
