Another option from Velo Orange is an adaptor that goes from a 1" stem to a 11/. this will allow you to use a longer stem and you will also be able to benefit from a removable face plate so you can pull the bars without taking everything off. Between a longer stem and handlebars that have a grip ahead of the stem end such as bullhorns, moustache bars, regular bars with bar ends, or even the bars that come with the bike.
