Description

43 ASC Carbon Aerobar Extensions (400mm)When designing these extensions we wanted to utilize carbon fibers' natural ability to be shaped into an aerodynamic form while still providing a good amount of strength and rigidity, hence ASC stands for Aero Shaped Carbon. Looking at the grip section, we have a 87mm rise from the base of the extension to the grip with the grip angle being set at 43 degrees.

When designing these extensions we wanted to utilize carbon fibers' natural ability to be shaped into an aerodynamic form while still providing a good amount of strength and rigidity, hence ASC stands for Aero Shaped Carbon.

Looking at the grip section, we have a 87mm rise from the base of the extension to the grip with the grip angle being set at 43 degrees.

The reason we went with a 43 degrees grip angle was to give a neutral wrist position which helps the rider to be in a more relaxed position and the key to speed is relaxation

The fit by the wrist area is designed to smooth airflow over the arm and to increase contact area which will provide some extra comfort and to give you more control over your bike. The shape was optimized using CFD to minimize drag without sacrificing strength.

Who is it for? The 43ASC is intended to optimize the aerodynamics of your existing bars but pairs exceptionally well with either the Race+ or Ergo+ armrest. Giving you the ideal supportive position which again will help you be relaxed while riding and as we mentioned… the key to speed is relaxation.

The extensions will fit in any aerobar that is designed for 22.2mm.  So can be used by any rider wishing to improve the comfort of their aerobar grips.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.
