Our road bar features a mild wing shape on top, clamping area wide enough for aero bars, mid-compact reach and drop. This is the modern bar for the modern road bike. Our Road bar wing section is small enough not to restrict hand movement when riding on the top and allows bar angle adjustment with out “locking out” your wrists. Shaping on the bottom side of the wing allows housing to be taped out of the way without the use of narrow housing channels or internal routing, both of which shorten bar life. Certified to EN, tested to DIN+.
Layup uses 3 different fiber types with different tensile strengths and tensile modulus, including High Strength carbon fiber. This helps allocate stiffness and flex where needed.
All carbon fiber is produced by Toray and uses tailor made Nano Epoxy Resin for very high impact resistance. Toray is the main supplier of carbon fiber for Boeing and Airbus.
Both the Road and Cross bar are made in one piece, not three pieces co-molded and glued together.
Bars are molded over an EPS mandrel to avoid wrinkles inside the layup during molding. Most other bars are molded over inflatable nylon bladders.
1.5K woven impact ends help prevent damage to uni-directional fibers from impact.
Reach 78.5mm.
Drop is proportional. Road drops are: 40CM 137mm, 42CM 140mm, 44CM 140mm, 46CM 143mm$390.00 (RRP)Add To Cart

The gravel bike handlebar that has everything but the kitchen sink.
If you are looking for comfort, control, and convenience the Kitchen Sink Gravel Bike Handlebar is for you. With widths from 41cm up to 53cm, these new low flare gravel handlebars can aid stability and control but at the same time provide really comfortable hand positions.
KEY Handlebar Features:
• 20mm of rise means less pressure on the hands and a broad range of fit options to accommodate a variety of gravel riding conditions.
• 7° degrees of sweep means the bar is positioned where your hands want to be, whether you're on the flats, the hoods or the drops during your most epic gravel ride.
• Low Flare (10° degrees) and a compact drop are perfect for road and gravel riders who prefer a more traditional road shaped bar.
Why 10 degrees?
Because it's the right balance between classic dropbar shaping and the ergonomic + comfort advantages of flare. A small amount of flare on performance road bike bars is quickly becoming a very popular option for this very reason.
Loop or Non-Loop?
Choose between two gravel bar styles: LOOP and a more traditional NON-LOOP. The Loop version provides an alternative riding position, a great place to attach gear, and the perfect spot for our custom storage solution: the Kitchen Sink Gravel Handlebar Bag. The bag was designed specifically to fit in the loop and allow easy (single hand) access to all your essentials for bikepacking and long gravel rides. In addition, we created a Computer Mount that attaches to the top of the bag to give you a secure and ideally located spot for your Garmin or Wahoo bike computer.
To get even more comfort and performance out of your Kitchen Sink Gravel Bar, add the ergonomic Cruise Control Grip System. The Top Grips provide an incredibly comfortable position at the tops by expanding the bar and giving you a wide area to rest your hands. And the Drop Grips give you an extra comfortable position while in the drops through an ergonomic style grip that helps spread load over your hands so you can stay in your tuck all day.
Top it all off with some of our Really Long Bar Tape which is specifically designed to be long enough to wrap even the widest gravel handlebar. Oh and it's super comfortable with just the right amount of grip.$199.99 (RRP)$249.99 (RRP)$199.99 (RRP)$249.99 (RRP)$199.99 (RRP)$249.99 (RRP)$199.99 (RRP)$249.99 (RRP)$199.99 (RRP)$249.99 (RRP) -
