RoadMasters are available at WalMart in the $129 range. cheap cheap cheap. Such low quality components that hours of work on a tune-up will not yield noticeable improvement. They suck and that's as good as it gets. the best thing about these bikes is their name. I see a lot of RoadMasters donated and thankfully I just re-donate them.
this is a real Road Master a 24oz can of beer. I used to see a lot of road masters near 5th & Seneca often buying one for me and one for my friend but drinking both before he made it to the RV.
Yesterday I salvaged a RoadMaster bottle cage from a bike headed for the scrap pile and it will soon be bolted to a work bench at HQ completing the circle
