I sell a sprocket that has a bigger hole to allow the dust cap to fit for $8 exchange on the standard sprocket (takes me about 20-25min to hog it out). Even with a good front brake, I don't like to build a cruiser with coasters tho due to the force applied to the bearings when that brake over heats. Got a lot of dead hubs here with cracked bearing races and one that split the race right off the rest of the hub. Usually, $60 extra will get you a cruiser with 7-speed rear wheel & good brakes.
