Delta Aero Cover
A clean front end is crucial; it's the key to clean aerodynamics, clean aesthetics, and superbike performance. It's the hallmark of a good rig.
Introducing Delta. Delta is a universal aero cover, the first product of its kind, designed to work with our existing brakes, stems, and aerobars, to create a completely-integrated front end that hides cables and components, guiding airflow smoothly past your bike's head tube and turning even the most basic rig into an ultra-clean superbike.
Delta was designed to be used on bikes with a standard head tube (such as the Cervelo P-Series, the Quintana Roo PRFive/PRFour/PRThree, the Specialized Shiv, etc). It is not meant for bikes with a protruding head tube (like the Felt IA series) or bayonet-style forks (like the Felt DA). Delta is meant to integrate with our Omega brakes and Alpha handlebars, and while it is possible that it would work with some third-party brakes or handlebars, we do not guarantee fitment. And due to its trim-to-size nature, we cannot offer returns on Delta.
- Simple elegance. The idea behind Delta is simple: cover all the front-end components and cables behind an efficient aerodynamic form. But the result is one of the easiest aero upgrades you'll ever find, and one that turns an entry-level bike into a world-class rig.
- Trim to size. Delta is designed to work with small bikes and large ones alike. It ships uncut, ready to be trimmed to size for your rig. We send with cutting guide decals to make the process easy and straightforward.
- Aluminium topper. The alloy topper serves several functions. After trimming the cover to size, it cleans up the cut edge, while also providing structural strength and keeping Delta in its proper shape. Finally, the three threaded holes on top allow you to set up Delta to work with Alpha One (putting pins in the two outer holes), or Alpha X/Sigma X (by putting one pin in the center hole). It's a simple solution that keeps everything working nicely.
Delta is designed to work with the broadest possible range of bikes, but it does have some limitations on where it can successfully be installed. Please read ALL of the information below carefully. Your bike must meet all of the below criteria in order to be compatible with Delta.
Frames/Forks: Delta is designed to work on frames with standard head tubes, and forks with standard rim brake mounts. This includes bikes like the Cervelo P2/P3, Orbea Ordu OMP, Quintana Roo PRFive/PRFour/PRThree, and many others. It will also work with some bikes that require use of the DM adapter, like the Specialized Shiv Tri and Shiv TT. It will not work on bikes with extended head tubes like the Felt IA, the Diamondback Serios, or bayonet-style forks like those on the Felt DA, Speed Concept, or Quintana Roo PRSix.
Stems/Handlebars: Delta's Topper is designed specifically to mate with the Alpha One aerobars or Alpha X aerobars. The holes at the top of the Topper receive set screws that act as retention pins, just as the aero spacers on Alpha One and Alpha X. While it may be possible to use Delta with a standard stem or a third-party bar, we cannot guarantee compatibility with anything other than TriRig cockpit products just mentioned. Use on a third-party product may require some DIY work on the user's end end, or an additional fastener to keep everything from falling forward.
Brakes: Delta is meant to cover TriRig Omega brakes, inclusive of all versions made to date. While it is possible that it could work with other centerpull brakes, compatibility cannot be guaranteed with anything other than TriRig Omega brakes.
Due to the trim-to-size nature of the product, we do not accept returns for Delta.
