Custom bolt on frame bags. these are made to measure with a blueprint or template from your frame maker for your exact bike. The other option is to bring me your bike.
these can be any style of frame bag I offer: Single zip, Dual zip, Top load or Cluster. probably not ideal for the convertible backpack.
the bags are built with a layer of 1" webbing sewn on the inside of the Xpac X51 Cordura fabric to hold the toothed spur grommets.
