RIRO Bicycle Internal Cable Stem 80/90/100MM Ultralight Aluminum Aolly Forged/CNC Handle with Spacer Road Bike Handlebar Stem

I've had some time using this RiRo bike stem and I like it a lot. It works well with full and semi internal cable frames. It's a bit heavier than a lightweight UNO stem, but it feel stiff and looks serious on the bike. If you want to save a minor amount of weight, you can go with titanium screws.

I can definitely recommend them at this point! Unfortunately they come in 80/90/100 sizes only.
