I just picked up a very nice old Raleigh M80. Need to raise the bars 1" to 1 1/2". Ahhh, so now I find out this is an old 1" threadless system (Head or fork tube is 1" o.d., stem is 1" i.d. on the bar and the tube ends) and everything I'm finding out there is 1 1/8". Are there 1" stems or adapters ? How can I raise the bars?
