The Profile Design DRV/GMR Gravel Drop Bar reworks gravel handlebar geometry around the DRiVe—Drop Reach Variant—fit system. Rather than relying only on conventional reach, drop, and width measurements, DRiVe identifies the drop position through a 73° line beginning at the bar bore. This approach progressively scales the reach and DRiVe position as bar width increases.
Its shape separates lever placement from lower-drop flare. The upper part of each drop remains straight, allowing brake levers to be positioned as intended, while the lower portion has a significant flare. A 9 mm rise at the tops and hoods creates a higher hand position than other Profile Design DRV bars.
The 105 DRiVe version is available in 36, 38, 40, and 42 cm center-to-center widths, with a 70 mm reach and 121 mm drop. The 120 DRiVe version is available in 40, 42, and 44 cm widths, with a 75 mm reach and 137 mm drop. Drop widths range from 438 to 493 mm for the 105 and from 480 to 520 mm for the 120.
Built from 6061-T6 aluminum in a matte black finish, the DRV/GMR has a 31.8 mm clamp diameter, 100 mm clamp width, and a listed weight range of 285–320 g. It accepts Sonic, Neosonic, and Supersonic aerobar bracket kits, while Subsonic, Legacy II, Airstryke, Flip Ergo, and Hypersonic bracket kits are not compatible. Internal cable routing is not included.
