How Long Should A Grind Usually Last On A Rim?

[Carlperkins]

heya, recently ground my rims and bought tnn lgm's for rear and heatsink yellows for front.

i was just wondering really.. how long do grinds usually last? do you have to do it every day? month? 6 months?

and how many grinds can a rim hold before its weakened?

just for the record my rims are the standard ones that come on the 2010 onza zoot, but looking to upgrade soon to some echo urbans.

any help much appreciated.

The lifespan for a grind to last depends how harsh you grind it whether its light,medium or hard and also depending on how often you ride too... I tend to grind mine every 3-4 months or when my brake is going pants or the grind fading. I have grinded my try-all rim atleast 4-5 times now as before i use to go smooth rim and always did medium grinds and to be honest theres still loads of life in the rim to do plenty more... Plus its always best to grind with your tyre on as every time you take your tyre on or off you are contaminating the rim which can effect your braking performance.

ahh, well id classify mine as a medium grind probably, its probably a light grind by now though. and i normally ride it around 10 hours a week. 3-4 months sounds ok, i couldnt be arsed grnding it every month or so.
