My mission: We make metric security bolts. Our intended use and mission is to help keep components on your bicycle safe from opportunistic thievery. Simply replace the existing Allen bolts with our security bolts. Each set comes with an L- key. The use of these bolts will drastically reduce the chances of a thief making off with your saddle, seatpost, stem, handlebars, racks, wheels and other components.

I don't respond to bolt fit questions. Very hard to do this remotely. See bolt sizing tips.

Shipping: All shipments will take 1 - 2 days to process. For example 2 day shipping will be delivered in 2 - 4 business days. All items purchased from are made pursuant to a shipment contract. This means that the risk of loss and title for such items pass to you upon our delivery to the carrier. Likewise, we do not take responsibility for lost items that track as delivered.

Coming by the shop: I do not hold regular hours. Please contact me and confirm a good time to come by. Happy to set you up with right bolts.
