The handle has a built-in magnetic bit holder, so bits lock securely into place and don't fall out mid-repair, which is especially handy when you're working on the roadside or in low light.

Yes, it's about the size of your palm and fits neatly into a jersey pocket, saddle bag or frame bag, making it a practical companion for roadside fixes rather than something you'd only use at home.

Yes, the 5cm alloy extension bar helps you reach narrow or recessed bolts without needing to partially disassemble your bike, which is useful for stem bolts, bottle cage screws and similar tight spots.

It's built from high-strength aluminium alloy with anti-slip knurling on the grip, giving it a solid, non-slip feel designed to handle years of regular maintenance use rather than a flimsy one-time tool.

Wipe the handle and bits dry after use in wet or humid conditions to prevent surface corrosion on the alloy bits, and store the set in a dry pouch or bag rather than leaving it exposed to moisture for long periods.
