High Quality Product Plus Exceptional Service

The aero chainring is a high quality, lightweight and great looking addition to my TT bike. I highly recommend it. Also the service I received was exceptional. Thank you!!!!

EZ Aero Chainring Guard

I’m not fortunate enough to have an unlimited budget so my builds are usually built on a bit of a shoestring, but I still want maximum performance! That’s what I love about your stuff, it offers top level performance but for us mere mortals have have mortgages and kids to pay for!!! Most parts are second hand or from AliExpress! My crankset/power meter are from China, but you guys were incredible in getting a crank cover that fitted. TT’s are triathlons are not just for the financially privileged, parts like these can help achieve high performance at a fraction of the price! Buy smart, not expensive!!! I’ve done a couple of races this season and it’s looking really good! Thanks again for your help. Chris.

5 star service

Bought a chainring aero cover towards the end of last season in September, the response and delivery was slick, these guys answered all my questions. Only just got round to fitting the product which didn’t quite fit, messaged these guys and had anotger one within 48 hours and a return label for the original one, cant get much better than that, would not hesitate to recommend or use them again.


Fitted perfectly, top notch product and fantastic customer service

friendly and nice service

I was able to get the information I needed quickly. I will do a review as soon as I install the product :)
