I have a problem similar to
RobbieTunes, but no deep carbon rims are involved. I have a pair of Clement Futur
α tires mounted to some AVA rims. The rims are shallow box rims, but, Jiminy Crickets (avoiding BF censors here - you know how I really want to express myself) the valve stems are the shortest I've ever encountered. I can pump the tires with my Zefal HP (locking chuck) but not with the Silca chuck on my Park floor pump (relies on the full engagement possible with a longer stem). I know I should probably just spring for a new locking chuck (Hirame?) but the current chuck also rather clumsily does schrader when I need it.
Unless I've gone completely blind, I believe these tires have removable valve cores. What are the shortest valve stem extenders I can get?
