- Single 29mm open bore drift for use with 1/2" rods

- Gel contains non-Abrasive plastic beads that provide increased surface friction - Allows for reduced clamping force, prevents crushing of expensive carbon parts (Brake lever/Bar, Bar/Stem, Stem/Steerer, Seatpost/Frame, Etc) - Prevents corrosion/scuffing and quiets creaking noises - Can also be used on non-carbon parts where an increase in clamping friction and/or a reduction in clamping force is desired - Always follow the manufacturer's torque specifications when clamping carbon parts

- Stainless steel measurement tool has gauges for all current headset bearing standards (Campagnolo, Cane creek, TH/FSA) - Includes inside gauges for headtubes and cups and outside gauges for bearings

- Installs and removes threaded cups for 386Evo cranks

- Star nut threads onto driver. - Driver slides up into guide tube - Guide tube fits over outside of 1-1/8" steerer - Hammer on round end of driver until steerer contacts driver-stop - Star nut is properly aligned and seated a consistent depth
