Hi All,

I have an old Specialized Rockhopper from the 1990s that I want to convert to a commuter/touring rig. I dont like the looks of straight bars with barends on them and was thinking of either converting it to drops or bullhorns. Drop bar conversions look pretty involved and more expensive so I wanted to know what bullhorn handlebars would work with my bike. Do I have the standard 25.4mm diameter? What handlebars would you recommend?

Thanks in advance for any help you can give!
