Wonderful service

The owner contacted me rapidly and ensured the product he would ship me would fit perfectly to my bike! Wonderful service!

Easy gains after easy installation + fast looks as a bonus

The chainring cover is a no brainer for me. Very easy to install, looks cool and most importantly gives me a +-3 watt gain, depending on the wind direction.


Fantastic. Super responsive customer service. Perfect fit first time. Great value. Well made. Aero!!!
