What customers say
The Safeguard Anti-theft Skewers earn high praise primarily for delivering superior security and peace of mind. Users consistently note the robust construction, finding these skewers significantly more durable than standard quick releases. Installation is straightforward, appealing to everyday riders. The core benefit is effective deterrence against opportunistic wheel and seat post theft in urban settings. The specialized key mechanism successfully frustrates thieves using common tools. While some note a slight weight increase, this is accepted as a necessary trade-off for enhanced protection. Overall, the overwhelming consensus views these skewers as an essential, cost-effective investment that dramatically reduces public locking anxiety, resulting in very high user satisfaction.
Know before you buy
These skewers feature a removable lever that acts as the key. Once you have tightened your wheel to the desired tension, you simply detach the lever and carry it with you, making it impossible for someone to loosen the skewer without the specific tool.
These are designed for standard quick-release hubs. The front skewer is compatible with 100mm spacing, while the rear skewer fits both 130mm and 135mm spacing, covering the vast majority of road and mountain bike frames.
Because the lever is the only way to loosen the skewer, it is important to keep it in a secure place, such as on your keychain. If you lose both levers, you would need to use a specialized tool or pliers to grip the internal mechanism, which defeats the convenience of the design.
Yes, they are built with chromoly steel shafts, which provide excellent strength and durability. While they are lightweight, they are robust enough to handle the stresses of both road riding and mountain biking.
No special tools are required for installation. You use the removable lever to tighten the skewer just as you would with a traditional quick-release skewer, then simply detach the lever once the wheel is secure.
