Blips are the piece of the eTap system that lets you put a shift button somewhere your hands actually spend time — the tops during a long climb, the drops in a sprint, the extensions on a TT bike — without giving up shifting access. These wired buttons are compatible with SRAM RED eTap and eTap AXS systems , plugging directly into the shifter port or into a BlipBox on aero setups, and once installed they behave exactly like the paddle on your lever: right for a harder gear, left for easier, both to move the front derailleur.

The wire length is the decision to make before ordering. These are available in 150mm, 230mm, 450mm, or 650mm cable length versions , and each pair ships with two Blips at a single length. The 150mm is the short run for tucking a button just inside the hood or right next to a BlipBox on aero extensions. The 230mm is the common drop bar length, reaching from the shifter port down into the drops or up onto the tops with enough slack to route cleanly under the bar tape. The 450mm and 650mm cover time trial cockpits, sprint shifters mounted deep in the drops, and any setup where the button needs to live a long way from where it plugs in.

You're not locked into one pair, either. The eTap system supports up to 4 blips for nearly limitless remote shifting positions , so a common build is two pairs — one length for the drops or tops and another for the aero extensions. The buttons themselves are low-profile enough to hide under bar tape if you want a clean cockpit, or mount exposed with the included hardware if you'd rather have a tactile bump you can find without looking....
