Presta TorqKey Bit Set

Engineered for long life
All Prestacycle Professional bits are made with hardened S2 steel, which is much stronger than most hand tools which are made of CRV Steel.  S2 steel also resists stretching, preventing rounded edges on the bits that could damage bolts. We apply nickel-plating to all Professional bits to prevent marring to Stainless Steel, Aluminum and Titanium screws and to provide a long-lasting finish. Specific hex bits have micro surfacing to reduce slippage when in use.

3-Piece 100mm: Hex 4mm, 5mm, Torx T25
6-Piece 50mm: Hex 4mm,  5mm, 6mm, Torx T15, T20, T25
