I the rims have no holes to thread the nipple so you have to get the nipple through the valve stem hole and then down to the proper spoke hole. All I want to do is drill another hole over the top of each spoke hole like a normal rim. Much easier to put spokes in and faster. Deacon Mark Cleary The recommended technique is a steel ended nylon line to direct the nipple pulled with a ceramic magnet. It's not difficult to do. ... and I'd certainly try that first. With a brass nipple :-? -- cheers, John B. The steel end is attached to a nylon cord, the magnet directs the steel part to the rim hole. Pull the cord and the nipple on the other end drops in place. Reading you and Franks explanations it seems as though the brass nipple is tied to the string which has a magnet tied to the other end which is drawn through the wheel by attraction to something made of steel. Given that the O.P. seems to believe that tubeless tires are a abomination of the Devil I think I'd just drill a hole in the inner rim surface... like a "regular wheel"? -- cheers, John B. Yes that was Mark's thought. Mine was, "why?" He likely won't be any better off than simply dropping the tension, lubricating spoke threads and tensioning the wheel, which is reasonably quick work. One more thought. Mark, before drilling your rim bed, see if a tire fits easily when you add a rim liner to the center section. Some tubeless rim designs don't have enough depth difference from the bead seat to the center well for hands-only tire changes. :-( I got some tires that don't allow hands-only tire changes :-( -- cheers, John B. |

Yes, a common enough problem. Rim designers don't observe enough difference in height.
