I have one of those 5/8" nutted axles from GEBE, and I wanted to put it on my rear wheel, which has the quick-release. The thread pitch is the same on both. Since I don't have a chain whip and cassette tool, I went to the local bike shop; one of those who cater to the rich. So I come in with shorts and a t-shirt. Mind you, I don't fit in with the demographic, so I end up waiting half an hour while they take their sweet time with their clientele. Aren't I one of them? Guess not. They direct me to their mechanic. I ask him if he could put the GEBE nutted axle on my rear wheel. Without looking at the wheel, he first tells me he doesn't think it can be done! After explaining things to him ("I don't have the right tools") he told me it'll take too much money ($28), and he doesn't know if I need a different axle to go along with the GEBE nutted axle? :-xI have the axle in my hand! And cones and spacers....they're in the wheel, and it's the same thread pitch! I told him it's the same pitch. Why can't he do it? I'll never go back to this bike shop again...I do not recommend this shop to anyone. I've yet to find a good one around here. I got the impression he just didn't want to do it. He even told me that the quick-release axle will hold up the GEBE mount and engine. Is that true? I'd like to believe him that the quick-release axle will support the GEBE setup. I looked up The Bicycle Tutor online and learned how it's done and D*****, I'm tempted to just buy a chain whip and cassette tool, but there are too many types of cassette tools.
