but trails rides do need a super beefy rear rim. they drill the hole to save weight and those hole don't weakin the rim that much at all. just because trails are all finess like doesn't mean that they are not hard on their equipment because nothing is farther from the truth. both rear wheel and cranks are brutalized in trials. btw mike i have been riding trials for about 2 month and i live it. its by far the most rewarding type of riding. also its not too expensive to get into. one of the main reasons i started riding trials is because there is no trials at all down here btw did you get my pm??
