To update the Racktime/Basil MIK adapter issue. I was able to purchase, from Propel, the Basil MIK adapter and mount it onto a Racktime basket. The Racktime adapter has the same mounting hole spacing as the Basil MIK so you only need to replace adapters to use your exsisting Racktime, or older Ortlieb, rear rack trunk bags or baskets.
