    Hello all..
    Ive got a Mammoth rim and I was wondering how many people use/have used one with a grind. How long would it last under however deep a grind? And how often did or do you grind it?

    Ive had it since April '03 with two grinds on it. Since the last grind I gave in and starting using tar, I havent had to grind it again since.

    Good cheap strong rim, just pinches too much.

    Why is everyone so against tar? I have been riding a very short time but seem to be doing ok with it. Am I missing something?

    Well, a local rider once told me he doesnt like how it's messy...weak complaint to me. The other thing I was told by a pretty experienced rider is that it can be inconsistent. Ive never experienced any inconsistency, at least nothing past how your coat wears down, but as far as a sudden unexpected slip, not here.

    I had a mammoth and ground it. I think the grinds really lasted me about 3 weeks, but that all depends on how much you're riding really (at the time I was probably riding 4-5 days a week). That was with a pretty deep grind, lets just say about "3/4". It was a cheap rim and held up well for me, but it was definitely too narrow... Rear-wheeling on slanted objects was a major PITA due to tire folding.

    Hardline, it may seem snobby to be against tar, but it's because when you use tar your brakes stop working when you get in the wet. If you only ride urban when it's nice out and don't ride comps, I don't think there are any problems with tar so long as you use it properly. It's a good temporary solution until you can figure out a way to get your brakes working better, but I wouldn't use it for tooo long :).

    I used tar on an old shitty rim, and it makes a mess, if you dont clean it your rim is pretty screwed, and in wet it slips.

    anyway..back to the topic...Sonic-how deep did you grind the rim?

    anyone else?

    Next time I grind my rim I'll make a video of it- seriously so many people have no clue how to do it. PPL ask me it all the time on AIM, look for it sometime soon.

    Funny you mention that Andrew, I was planning on filming it next time I ground my rim... now that Dave's camera is functional :). Film it anyhow though cause it's going to be a while before I need another grind.

    Deep, deep, grooves, grind definitely lasts me longer than 3 weeks.

    And the only reason I really resorted to tar is because my HS33 lever is having some problems internally, so I cant set it up to be as powerful as it should, so it's like Bill said only use it when your brakes really arent working the way they should.

    Andrew, do it, equal Tart's CK vids. :cool:

    i grind my rims, although i do not think that i have the right technique, my brakes dont work as well as they should when i pit the grind on, maybe i need new pads.

    the main reason i stopped using tar was becuase my pads would not unlock and it really was not fun during drops!

    just grind, it is damn well worth it!

    If your pads wouldnt un lock, its sounds like you painted it on, I just get a small bit and rub it round me rim til you can see a bit of blak on your rims.

    It only takes 5 mins be fore every two rides.

    Also that grind vid would be helpful cos i wana grind so i dnt have no brakes in the wet but i dnt wana reck me rim walls before i do it wrong?

    Cheers Mat

    Absolutely right. Tar must be applied properly if you expect it to work. As for tar turning to oil in the wet.... you guys must be using some weird tar.

    Besides the mess (and apparently, the lost art of tar-application), the major downside to tar is EXTREME LOUDNESS.

    tar should go on like a wide pencil line, all the way around the rim. no more.

    and i dont ride in the wet, so i dont mind. it sucks though, if i ride through wet grass, i have to let my brakes dry, otherwise its just like i oiled my rims... :(

    In aid of this post I have just ground my rims, and to tell you the truth it was piss easy. A lot easier than i thought and the breaking after I did it seemed pretty good ( Although i did only ride around the garden and hopped about). One good thing is its not quite as loud as tar but that will be found out later when I go for a ride. If you are worried about ruining your rim try it on an old one first but I found it very easy to do and it only took 5 minutes.
