How come it's the second-tier manufacturers, making the low-Q/aero running?
Maybe they see a niche in aero where they are not up against Shimano/SRAM/Campag, so they can make their own running. On Q, they are no better than Omnomnom (135mm) 7710 (136mm) or Record Pista (131mm)
@xavierdisley says just under 140mm for the Pistard Air. Vision NS is 137mm
