9 metric hex sizes from 2 mm to 10 mm plus T25 Torx for broad bike component compatibility. Constructed from premium chrome-vanadium steel with a satin chrome finish for durability and wear resistance. Innovative sliding design lets you switch between L-shaped and T-shaped configurations, delivering maximum leverage in tight spaces. Secure grip: each hex key is treated to improve grip on fasteners and reduce slipping and damage. Applications: suitable for common bike components such as brake caliper bolts, derailleur bolts, stem bolts, seat clamps, crank bolts, and other fasteners that use hex or Torx sizes. Use scenarios: - On the trail: perform quick roadside adjustments to brake calipers or derailleur screws in hard-to-reach areas. - At home: routine maintenance like tightening stem bolts, seat clamps, and crank bolts. - In the workshop: install or upgrade components that require hex or Torx fasteners, including T25 applications.
