These bolt-on skewers replace the lever mechanism with a hex key bolt. This creates a lower profile and makes it significantly harder for someone to remove your wheels without the proper tool, offering a simple layer of theft deterrence.

Yes, you will need a standard hex key (Allen key) to tighten or loosen the skewers. Because they require a tool, they are less convenient for mid-ride wheel changes but much more secure for daily commuting.

The standard version fits most traditional bicycle dropouts. If your frame has exceptionally thick dropouts—up to 10mm—you should opt for the XL version to ensure there is enough thread engagement for a safe, secure fit.

These are designed for standard 100mm front and 135mm rear hub spacing. As long as your bike uses standard quick-release dropouts, these will be a direct fit.

Yes, you should tighten them to 7 Nm. Using a torque wrench is recommended to ensure the skewer is secure without over-tightening, which could potentially damage the threads or the dropout.
