The Halo Hex Key skewers in Red color for road bike front and rear wheels incorporate a lightweight Cr-Mo threaded rod with a hexagonal wrench attachment and alloy end covers. These skewers offer greater security and a lighter weight than quick release skewers.They incorporate a steel ‘no-turn tab’ to prevent the end cone from rotating whilst doing up or removing. There’s also a 15 x 3mm cone spanner recess cut into nut, just in case the ‘no-turn’ tab cannot operate.
