Envy Flavio Pesenti Reaper Bars V2!!! The Envy Reaper bars are made from aluminium, and also are one of the lightest bars on the market. Weighing only 1.9 pounds, and now in a XL version of 25.65″ tall and 23″ wide. Reaper Bars are choice aluminium bars, we would advise riders that aluminium bars are not as strong as chromoly bars, and so if you are prone to breaking bars we would recommend going for the stronger chromoly bars. Aluminum bars with a slit are compatible with IHC, mini HIC, and threaded compression systems only as is. For ICS a starnut must be installed in the bars. Compatible with full size SCS only if the slit is removed. Not compatible with HIC.
