You protect your beautiful bike with the beefiest U-lock - but have you protected your components with the same care? Opportunistic thieves can go for your jugular and steal very important parts off your bike like the wheels, fork, seat post, saddle, or stem. Send them away bitter and empty-handed with Pitlock's range of super-security bolts. The Pitlock Pit-Stopper is a tiny sleeve that fits inside an existing hex bolt and can only be removed with the included Pitlock screw. This keeps your hex-bolted components safe by thwarting a thief's attempts to remove them with Allen keys. They come in sets of two and are available in different sizes, so be sure to check your bolt dimensions using a hex wrench before ordering to receive the right ones!
