I've Ground My Rim.

If your pads have tar on them, get it off, as well as regrinding the rim to make sure none of the tar's on there from the pads.

Grind with Koxx Browns has insanely good hold anyway, so you can still do stuff like an amateur - as I hardly have the best technique and it held/hold (going back to Bloxx once bike is up and running again) fine.

Sounds like theres an underlying problem, bleed the brake maybe?

Tried that yet?

Tar gives a different feel to a grind. With tar the brake is on or off, when it's on it'll stick. With a grind there's much more modulation and if you're not on something enough you'll slip off.

You're not gonna get the same feel with a grind as you do with tar. That could be your problem.

tar sucks-its far too grabby-i dont see why you bother having such nice pads if you used them on a tarred rim....cudda just gotten away with some old blacks :P

A brake IMO cannot be too grabby :D

For me, black pads on any amount of tar is crap.

I think i'm starting to realise that i'm used to a super hold from the tar, therefor making a grind seem crap.

Probably is, it does have a different feel, but over all i just don't like it.

My brake is fine as far as i know, and can't be botherd to bleed it.

If i was you, i would take it to someone who knows what they're doing with a grinder, get them to grind your rim.

Then get someone to have a look at your pad set up.

Then if it works, it works, if it's not up to your standards, then go back to using tar.

Get someone used to a grind to ride your bike, and see if they feel it's a shit brake, or a good one and your expectations of a grind are too high.

No one here had ever ground there rim with more experience than me.

Then get someone to have a look at your pad set up.

The pad setup isn't perfect due to having a wide rim in a thin frame, but it's as good as i could get. All the pad is touching the rim and everthing.

Then if it works, it works, if it's not up to your standards, then go back to using tar.

I have :D

You need to move somewhere less shit dude.

Whitby's a goodish place for riding, but no one here does trials really....

including yourself?  :D"

Well, i have now, but i have nothing to compare it to.

Jt, i agree with you with the brake theory on the better it grabs , the better it is. i recon, if you want to use the bike for modulation, manuals etc, then get a rear disk. maggys are ment for sheer lock imo. also, if u get grabby brakes, you learn to manual properly, with your body weight , as apposed to using the brake -- just like some freestyle bmxers.

As for your grind.... clean the rim off with some vodka, then put TAR on it ! so u have a grounded rim with tar.

this is what i have done (previously used just tar) and the lock of the back wheel feels sooo much more powerfull.

you can also put bit more tar on than on smooth rim too, as it doesnt clog up like on smooth rim.

the point with a grind is that you should have good braking in all weathers. smearing tar on doesn't really help the wet-weather performance eh?

if you want tar, you don't need grind. if you need tar on your grind, you did it wrong.

there are better uses for vodka than rim cleaning. use something non-consumeable to clean the rim with instead. :D

Well, i'v just sanded it down a bit now, and it feeling like how it was, the rim looks a bit nicer aswell, so it wasn't a compleete loss. And i know what a grind feels like, so that can go in the experence bag.

I don't want to not relie on my brake. I don't care if i don't get better, i just want to ride. There people saying get used to it and you'll become a better rider, well, why don't you strap lead to your bike and ride with that, that'll make you a better rider.

My mistake was assuming that grinds were the dogs bollocks. Thats why i sometimes posted telling people getting a grind. I tell people to get profiles, but i have never ridden with one. I soley base this on peoples opinions.

So, yeah, learn by your mistakes.

Grinds ARE the dogs bollocks and you have f**k all to put in your experiance bag.

Saying that the pads arent set up properly because of wide rim/narrow frame is no excuse. Do what other people do and take the pads down to a reasonable size.

With a grind you need everything perfect, amazing pads set up is crucial. With tar it doesnt really matter one bit how they are set up to be honest. (looking at my brake as a beginner)

Writing off a grind without trying to set it uo properly is a bit silly and some day a grind will ome in handy when your tar turns to shite!

Agreed.

Right Jon.

Take the whole brake system off, take the wheel off, and the tyre.

Clean the brake, really well, washing up liquid and warm water and a brush, do the same with the wheel, really well, use muc-off if you have it.

Bleed the brake. Do it well.

Clean the pads soo throughly, and if you have a wide rim, file them down, make sure there flat, clean with more fairy liquid, swill off.

Grind the rim, do It so the lines are verticle, drag it quickly, make sure the disk is clean ish.

Now set the brake up, really well, take time, flat pads, make sure there flat vertically as well, look in the FAQ as well.

Then come back and say it doesn't work, I bet your setup at the moment is filthy, the bleed is old, its set less than wonderfully, the rim is still caked in tar around the edges, and the pads are covered in inground dirt and tar residue.

The brake should lock whenever, and never slip, anything less, and somethings wrong, if you follow that (please correct me if i've left anything out).

But i can't be botherd to get everything perfect... It's too much effort when you can just slap on some tar, and hey presto.

Thanks for typing all that out, but like i said above, i don't want to waste time dicking about with it anymore.

I'll wait untill i actulay ride on someone bike with a good grind, then i have something to aim for. Becuase at the moment i have no idea of the potential of a grind.

If you arent willing to learn to land on top of objects, fine, stay crap I guess  :-

I can land on top of things, but if i can get away with it, i prefer to worry about where i land really.

Becomming a better rider isn't my goal really. If my aim was to become a better rider i would strap lead to my bike, use magura blacks, or even v brakes. And i would have a shit bike. Then you would improove quite well.

and what is wrong with v brakes may i ask.....

anyway riding a shit bike wont make you a better rider....ive ridden shit bikes for ages and they didnt make me better

setting up your bike properly is vital, if you set up the rest of your bike like you have your brakes then it must be 1 shabby monster to ride....its your choice, but you will soon find out 1 day, when you accidentally forget to top up you tar, go for that big gap and bam! your brakes slip and you are on your arse-thats when you realise you needed to listen to us, get the grind and set up your brakes properly....

Well, i'm going to end up on my arse if a stick with a grind (Y)

Say what you want to say, but i'll wait untill i have a go on someones bike that has a good grind, then i'll think about going back to it.

IMO V's are crap.

Why, cos you can't set them up properly, I have a video clip of me landing backwards after a blunt and my brake holding. I wasn't holding hard as I actually wanted to roll out backwards yet my "crap" v brake held my whole 13 stone with no problems.

Now tell me my brake's crap?
