parallel nylon mount for $2.06 + free shipping. perpendicular nylon mount for $2.39 + free shipping. both mounts are of the same quality of the twofish lockblock and bikeblock mounts but much cheaper. these items ship from china so it may take several weeks for them to arrive. i have several of either mount on my bike and use them for everything. two of them hold my u-lock onto the top tube and seat post, while two more on the handlebars hold two flashlights. another is used on my helmet and one more for holding my bikeglow battery compartment on the seatpost. i've even used the mounts to hold my tire against the rim as i'm remounting it.
