EZ Aero Front Derailleur Guard (Patent Pending)

"Avoid power failure due to weather conditions with the front derailleur guard, it has also been designed so that it protects derailleur from the wind throughout the whole range of movement".

Smooth the airflow of your front derailleur and save a massive 2-5.8 Watts across 30-50 kph.

On the 31st January 2023 at Silver Stone Sport Engineering Hub "wind tunnel" 

EZ Gains independently had the EZ AFDG fully tested across YAW angles and 30/40/50kph wind speeds, and the results are out of the park.

50kph 5.8 Watts, 40kph 4 Watts, 30kph 2 Watts.

0 Yaw Watt Saving 30kph = 1.4 / 40kph = 4.1 / 50kph = 5.8

25 grams

Available for DI2 11 - 12 Speed Models - 105 / Ultegra / Dura ace

(Please not the 12 speed DI2 version has 20% less mass than the 11 speed DI2 & SRAM 11-12 speed the Watt savings on the 12 speed DI2 will be less then above but still a large saving "predicted 20% less", we intend on another visit to Silver Stone Wind Tunnel soon to verify exact Watt saving to the 12 speed Di2).

Please see the attached wind tunnel on science page.

Used in Ironman Triathlon Pro Field / BTF / ETU / ITU and inspected

Awesome! Only used a couple events so far this season but seems to do the job- quiet and speedy in aero

British Champs Medal!

Thank you so much to EZgains for their great innovations 💡, I now have all 3 products fitted on my TT bike, adding the front derailleur guard for its first outing a the British Duathlon Champs coming away with a podium spot. It looks pretty slick and I rode a PR speed on the course.

Ben Goodfellow
Best of both worlds! Full gearing range of a 2x setup & similar reduced aero drag of a 1x

Great product. Easy to install, lightweight weight and goes most of the way to removing the aero penalty of having a front mech.
Running a 2x setup is so much more versatility than 1x but the aero penalty can be pretty significant.
Making this front derailleur guard is a game-changer for me.

Dylan Gwynne-Jones
Perfect addition to your bike

Very easy to install, looks good and feels fast.

Henry McMahon
Easy to set up

I have no way to test it but it feels faster, the average speed with my threshold intervals today was about 0.5 faster!
