(as in Engineering Bastard File - grip surface)
130mm Single Ply, semi flange.
Wire-on groves, supplied complete with plastic screw-type expanding flanged end plugs.
MTB & BMX suitable...(flange clears most STI levers etc.)
For those that want a full control, narrow grip.
Logo just appears ONCE on each grip... rider can select to have it under palm, fingers on none (straight down under)
