High quality bits
Prestacycle high quality 1/4″ hex tool bits for use on Bicycles and much more. Our bits are compatible with all Prestacycle hex-based hand tools, and are industry-standard to fit all other tools that use 1/4″ hex bits.
Prestacycle bits sets do NOT contain U.S. Philips heads, which were specifically designed in 1932 to round-out as an alternative to torque tools. These are modern ANSI standard (compatible with the discontinued JIS standard) and can be used on any bicycle cross head bolt.
Prestacycle hardened CR/V Bits offer the same quality and strength as most major Brand’s best tools.
