The Delta Extension System
The revolutionary cockpit at the pinnacle of aerodynamic engineering.
Delta Extension System
The Delta Extension System is the latest in cutting-edge development from WattShop.
A masterpiece of customisation and integration, the Delta System is the only cockpit where every design element is configured to suit the requirements of each individual rider.

delta/dɛltə/noun/Δ:
a difference between two things or values.
Denoting change in maths and physics, the Delta System is all about measurable improvement through personalised change. The system is built without compromise: every aspect is tailored to the individual through the extensive analysis of rider data. Complete integration enables aerodynamic optimisation of the cockpit by eliminating drag-inducing interfaces and inefficiencies.
With years of extensive aerodynamic research and development behind this world-class component, the Anemoi Delta is set to revolutionise TT cockpits as we know them.
From Conception to Completion
The Delta Extension System made its debut with Dan Bigham at the 2023 UCI World Track Championships.
Since then, we've been working closely with amateur athletes and professionals, including World Tour riders, to engineer fully individualised cockpit systems.
Recommended for riders who have already identified their optimal aero position, we then eliminate any aerodynamic inefficiencies, delivering a solution that is as performance-driven as it is personal.
Our design process is intentionally meticulous: After receiving your measurements, we will send you a drawing of the proposed cockpit layout, followed by a multi-jet fusion (MJF) printed prototype for assessment on a static trainer. Final refinements are then incorporated before producing the finalised Delta system in 3D-printed alloy, delivering a fully integrated, race-ready solution tailored exclusively to the rider.

Precision at every stage
Easy-to-follow guides
Clear instructions with diagrams enable you to measure confidently and accurately at home.
Expert fit review
Every fit submission is reviewed by our team. If something looks off, we’ll contact you before printing begins.
Test before you commit
You’ll receive a 3D-printed mockup to test before we finalise your system.
Peace of mind guarantee
Your cockpit only enters alloy production once you’ve approved the fit and ergonomics.
FAQs
How many Watts will I save?
Extensive wind tunnel testing confirms that the Anemoi Mk2 consistently reduces rider CdA by approximately 0.003–0.006 m². Our custom risers alone deliver savings of up to 0.003 m². While individual results vary based on system configuration, these figures provide a strong benchmark for expected aerodynamic gains.
How much does the system cost?
The Delta Extension System is priced at £2666.67 + VAT. This includes an initial cockpit preview, an MJF-printed prototype, the final design, and full support from our Design Team throughout the entire process.
How long will the system take to manufacture?
Please note that timelines may vary from system to system. However, our general goal is to have the final version of your Delta System ready to ship within 8–10 weeks. This is an estimated timeframe, and we will keep you updated on the expected completion date.
What's the difference between Anemoi Mk2 and Delta?
The Delta System is a fully integrated, custom-built solution, while the Anemoi Mk2 prioritises modularity and adjustability. Although the Anemoi introduced enhanced personalisation beyond standard mass-produced cockpits, we saw the opportunity to go further. The Delta was developed to deliver a level of fit and integration that off-the-shelf componentry simply can't achieve.
Is it compatible with my basebar?
Yes, it can fit any basebar. Thanks to our growing range of mono-brackets and conversion spacers, the Delta System is compatible with most leading basebars. If your basebar isn't listed in the form, it will still fit, but we'll require some additional time to manufacture the necessary spacer or bracket.
Will you fit the Delta System for me?
While we don’t offer an installation service for the Delta Extension System, its straightforward bolt-up design makes self-installation simple. Our Design Team will be available to support you throughout the process.
How much does the system weigh?
The system is optimised for both weight and performance. Due to the bespoke nature of each build, precise weight specifications cannot be provided.
Is the Delta System UCI legal?
Yes, the system can be used in UCI races.
