Sanding an "Alternative" to grinding rims!

[Lrn2Trial]

I haven't tried grinding rims so I can't comment on how effective or efficient they are, but I thought I'd post this to give you guys an "alternative".

i think that´d last me 3 rides...

...And then you put your tyre on and contaminate the rim. Siiiiccckkkk

How does it feel and how does it last?

ive used a 40grit paddle disk on a grinder to sand down parts of my frame and i could possibaly see it working. it wouldnt be as effective as a grind, but it'd properly be better than a smooth rim

Interesting..
I've found a new technique I'll never use..


Unless, you know I have a head injury and suddenly become retarded..

I saw a video i think it was TNN rim grinding and he says to leave the tire on to prevent contaminating the rim,

but i removed the tire just to take the paint off without the hassle of the tire being in the way,

but overall this rim modification is better than standard rims but i cant compare to rim grinding and also because i had the tire off when sanding the rim i haven't noticed the difference between a contaminated rim or if i sanded with the tire on.

let me know what you think of this, does it look good or bad, should i stop sanding and start grinding?

deffo.

Im new to trials got my first bike in march so i cant comment on how good this method is but i decided to do it after seeing rim grinding.

Before sanding when i was braking it was very noisy and the wheel kept slipping through the brakes a little because the paint on the rim was too smooth but after sanding its allot better doesn't slip and less noise.

Grinding <3

it was very noisy

This is normal, the bite comes from pad wobble, They vibrate a lot more so you get this lout squeak with your braking (most cases)

I used to run flapper wheel grinds a long time ago, its not as good as a proper grind though

[Muel]

I once did this in order to sand the grind off a rim, because the only pads I had were Heatsink Snowies and it would have eaten them alive. One freshly sanded rim and no booster later, and I had the loudest brake I'd ever heard. It was ear-splitting (literally, it was physically painful to ride after half an hour).

I used to really rate Onza Citrus Greens with a soft-pad grind. Think they were about 40 grit.

Did it as they were quite soft, but it rained a lot. Turned out real good!

I ran the citrus yellows on a flapper wheel grind, it was ok for me then, but I had no idea about stuff back then. That was when I had my T. rex and the first time I met everybody on the Leeds group ride in 2011. Back when flipp has his Marino

yeah it contaminates the rim

plus im too lazy to take off the tire anyway so I do it like this
