When I ran IRS hubs I stripped more screws than I can remember...seems to me that even the 2mm ball end would strip out. Now I just take off the wheel and use a straight allen wrench, screw heads now last a lot longer
Stop being lazy and start taking off the wheel first, never mind...you can afford to buy new screws
at $13 for 100 screws. I can afford to replace them every month for quite a while. maybe longer then rc. and P2 you know me. there is no one lazier them me. it is all about convenience. I don't change my tires until I run out. this weekend I ran a 40mm rear and 38mm front. there were spots that you could see the wheel. I finally changed them out for next weekend. but hey, I turn the fastest lap on the track 17.5 or 13.5 so maybe that is the fast setup. lol
