Profile Design 39AH Aluminum Extensions Size:400mm Threaded BB Shell Width: 68mmThe 39AH is intended to be paired with our pad wadges to convert non tilting aerobars to have a 10 or 15 of tilt. The name means 39, aluminium high rise. The extension angle starts at 54 and when adding a 15 pad wedge, balances the angle out to 39 (54 15=39). Likewise when paring with a 10 wedge you get a total of 44 (54 10=44). The grip is long enough that it can be shortened for use with the 10 wedge. Features Extension Shape: Aero shape consistent
