So you have aero socks, but you're looking to add more even more aero savings to your race day kit. Enter Aero Sleeves!
To test out just how many Watts you could save by adding aero sleeves, we headed to to Silverstone Sportes Engineering Hub to conduct tests. As with all our testing, we use independent engineers to ensure trustworthy results.
 
TEST PROTOCOL
Tests were conducted at a speed range between 35 and 55kph, at 0 degrees of yaw, to cover the full range of speeds that can be expected in criterium and road racing. 
The athlete selected for testing was Jean Spies, South African Olympic Track Sprinter. Jean provides a very stable position with highly repeatable test accuracy. 
Riding position and cadence was kept constant between both tests to ensure accuracy.  
KIT
The kit used for the baseline test are the Rule 28 Obsidian Bib Shorts and Glitch Jersey.

35 40 45 50 55
Glitch Jersey and Bibs (W) 162.65 240.22 337.60 462.72 609.49
Glitch Jersey and Bibs w/ Aero Sleeves (W) 162.00 234.90 327.14 440.20 588.62
Savings with Aero Sleeves 0.65 5.32 10.46 22.52 20.87

Do Aero Arm Sleeves Work?

Yes! Aero Sleeves reduce drag across all speed ranges tested. At 35kph, savings were minimal (0.6W), which is within the margin of error for testing. Above 40kph however drag decreased significantly. Maximum savings were achieved at 50kph (22.5W).
For reference, Jean in 1.91m and 100kg so savings for smaller riders will be proportionately lower.
