パークツール ヘックス 10mm ロング グリップ付き (HT-10)

The long handle gives you serious leverage for stubborn crank bolts, and the rubber grip actually prevents slipping even with greasy hands. Fit perfectly on my Campagnolo cranks and made the job way faster than I expected.

I was dreading removing my crank until I used this tool—the extra-long shaft gives you the leverage to break stubborn bolts loose without stripping them. The rubber grip makes it comfortable to really torque down, and it's a solidly-built piece that feels like it will last forever.

Finally, a hex key that fits Campagnolo cranks perfectly – the grip makes a huge difference when torquing down those tight bolts. This thing is built solid and feels way more comfortable than using a standard Allen key on my Ultra-Torque cranks.
