Brand/Model: Extralite HyperStem

From Extralite:

The Hyperstem is tested well beyond the EN safety standard, Extralite is confident that the Hyperstem can be used in a wide range of applications, including road and cross country. Each stem is expertly machined in 3D CNC from a solid block of 7075 Txx aluminum, resulting in the best possible stiffness-to-weight ratio. As the connection between the bicycle's handlebars and fork, the Hyperstem's overall stiffness plays an essential role in conserving expended energy from the rider's upper body, through the handlebars, and into the main frame of the bicycle. This is especially important to consider in sprints and climbs - often the deciding factor in competition.

The Hyperstem combines minimalist machine work and grade 5 titanium hardware in an exquisite design in order to shave as much weight off and already lightweight bicycle component. The Hyperstem is an ideal option for the rider concerned with overall build weight. Easy to install with your current bar setup without unraveling any bar tape, the Hyperstem uses a simple 2 piece, 4 bolt faceplate design and is compatible with all 31.8 mm clamp diameter bars and 1-1/8" steerer tubes.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
