But.. it's not like that at all. I have many friends who run drilled rims and ride every day, and ride hard. Mind you most of them are lightweights but the fact is, trials is generally not super hard on rims, we just need all the width we can get to get rid of tire foldage. Thus, drilling the rims doesn't compromise the strength to a degree that it affects most riders. Obviously, you need to drill the right size holes and properly - and the guys I know who drill rims are certainly not hacks in any sense of the word.
