I’ve got a set of Park conventional nipple wrenches but have got a set of deep section carbon rims with no exposed square on the nipples to get he wrench on. The only access is down the rim onto the head of the nipple – ie the slotted head with the spoke thread poking though.
Is there a wrench available for internal adjustment of slotted nipples ? I’ve seen them available for hex and square heads but not for slotted. I’d use a decent screwdriver but on a few of the spokes the protrusion of the spoke thread prevents the screwdriver blade from engaging with the nipple.
Any ideas guys ?
