So kings and others sell this wheelset for around 200 and it comes with a front drum and rear coaster brake. Now I've looked all over but it doesn't say it comes with a tab for a Wal Mart bike. I really want to buy a set because I need better wheels but can't justify the cost if I can't use that drum....thoughts on how I could use it if it don't come with a tab big enough for a wally world bike!?
