Pitlock Skewer and Ahead Lock

(2 customer reviews)


Secure your front wheel (or rear wheel or seatpost) and your headset with the unmatched security of Pitlock. This set is an excellent choice for those who lock their frame and rear wheel to racks using a U-Lock. Skewers range in size from 22mm to 250mm to fit any application. For help measuring your bike for Pitlocks, please see our measurement guide.

This set comes complete with all the necessary components for installation: one 5mm skewer, locking mechanism, topcap, 6MM bolt, and up to two keys. Available colors are silver and black.

See below for additional product and sizing specifications.

SKU: SET04GA Category:


Pitlock’s “SET04 GA” comes with a skewer of your choice (front wheel, rear wheel, or seatpost skewer), and a locking topcap to keep your bike’s frontend intact.

The wheel skewer uses the legendary Pitlock locking mechanism to ensure that commuter and high-end wheels alike stay on your bike instead of in a thief’s hands.

The Pitlock locking topcap is designed to fit just about any bicycle with a threadless headset. Consider this: a fork with a threadless steertube can be stolen simply by loosening the headset topcap bolts. It’s easy to see why it is so important to not only lock your front wheel to your fork, but also lock the fork to the frame. Available in both black and silver, the Pitlock ahead lock looks good, but works even better.

All Pitlock parts (with exception of the ahead lock) are cold-forged and CNC machined from high-grade stainless steel. The ahead lock uses the same steel for the bolt, but to save weight the topcap is machined in aluminum.

Worried about losing your Pitlock keys, or needing to change a tire on the road? Purchase a keychain tool and never be without your Pitkey again.

Additional notes:

  • The 240mm “joker” skewers are fully threaded, and will need to be cut to length. Cutting skewers is a fairly common need, and only requires a hacksaw or Dremel tool.
  • Each skewer is actually 10MM longer than the length shown. This is to account for the locking mechanism, which requires 10MM of space.

    This should slow them down a little.
