Profile Design Wing 20c+ II Base Bar

Profile Design Wing 20c+ II Base Bar is a carbon base bar built for triathlon and time trial bikes, updated to a slimmer profile that takes advantage of current UCI rules on frontal width. It runs on Profile Design's A3 platform, which opens it up to the A2 Standard, A2 Race, and ASC Pro extension brackets, so you're not locked into one setup when your position changes or you want to switch extensions down the line.

The base bar's real advantage is how much fit range it packs into one part. Flipping the bar shifts your hand grip and aerobar height by 20mm, and armrest offset adjusts from -92.5mm to -10mm while armrest width runs from 124mm to 254mm, both in fine steps rather than a couple of fixed positions. Stack height ranges from 64mm to 84mm, letting riders chase a genuinely low position without giving up the ability to fine-tune arm pad height the way some low-stack aero bars force you to. Internal cable routing keeps the front end clean and works with Di2 setups, and at 265g, this is a bar for time trial and triathlon riders who are already fitting their position down to the millimeter and want an aero base bar that adjusts with them instead of dictating a single fixed setup.
