A new chapter.

When you do something time and time again, you can become insensitive to the world around you. In manufacturing, designs grow old as one becomes comfortable with what works. Thomson, on the other hand, not only has its hands in the cycling industry, but aerospace as well -- always keeping its approach fresh. It has also consistently expanded its cycling line over the last two decades, and the Carbon Road Handlebar is a milestone for this stalwart company.

This is the first product not manufactured at the US facility, and the first product not cut from a piece of aerospace grade aluminum. But the aerospace connection remains with these bars, as they are made by Toray, the same plant the pushes out carbon fiber components for Boeing and Airbus. And the to ensure a Thomson level of quality, the bars are certified to EN and tested to DIN+ standards.

The bars are made using Nano Epoxy Resin for very high impact resistance, and they are made in one piece -- not three pieces co-molded and glued together. An EPS mandrel, unlike other manufacturers who commonly employ an inflatable bladder, is used during the layup and molding process to avoid wrinkles inside the layup during molding. For added strength, 1.5K woven impact ends prevent damage to the uni-directional fibers during impact.

This results in an incredibly strong structure with stress risers reduced to an absolute minimum. Structure is one thing, ergonomics and ride quality is another whole story. Because this is Thomson first foray into carbon handlebars, they have the advantage of starting with a clean slate. By working closely with athletes, Thomson has dialed in a shape that is destined to become a favorite of the pro peloton.

There's a mild wing shape along the top, with a clamping area that's wide enough for aero bars, yet subtitle to not restrict hand movement when riding on the tops. The shaping on the bottom side of the wing permits cable housings to be taped out of the way without narrow channels or internal routing -- both of which can hinder bar strength and lifespan.

Reach is 78.5mm and drop is proportional to width. They are: 40cm/137mm, 42cm/140mm, 44cm/140mm, 46cm/143mm. The finish is a natural carbon fiber with graphics applied before a clear coat for a long-term, quality sheen. Thomson recommends a torque of 5nm, and the Carbon Road Handlebar comes with friction paste for installation.

Thomson makes some amazing gear and they never cut corners. I have run these bars on three different bikes now and love them. They have a great overall shape, with a slightly flattened / egg shaped top section which helps disperse hand pressure when riding on the tops. Also, their construction method is pretty neat.

https://www.bikethomson.com/product/drop-bars/

"The 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."

Toray is used by a number of higher end bike manufacturers, including Pinarello, which uses a very similar construction process as well.

"Both the Road and ‘Cross bar are made in one piece, not three pieces co-molded and glued together. The bars are molded over an EPS mandrel to avoid wrinkles inside the layup during molding. Most other bars are molded over inflatable nylon bladders."

Thomson makes some incredible products, and I'll make an effort to use as many of their components on my bikes as possible. These bars are cool. The tops are thick and meaty- Very supportive when you're gripping on, as you power through the last big hill. Excellently designed, with minimal flair. Completely recommended.

Love them!

I've got the 46's and love the shape and feel of these bars. The top portion is flat enough to give your hands a nice rest but not too wide that the tops don't fit nicely in the hand while gripped. The drops are at a very comfortable level and comfortable on the hands in extended use. The porting for the wiring of the brakes and shifters is excellent, as they dive out of the way of your grip. For the price, they are an excellent value.

Do these have stealth ports or all external?

All cable routing is external; there are grooves for the cables on the underside of the bar.

How do these bars work with Campagnolo 11 speed shifters?

These handlebars will work perfectly with Campy 11 speed shifters.

deep drops, light weight

  • Familiarity: I've put it through the wringer

Great handlebars, they've got a fairly deep drop which isn't necessarily a bad thing, just gets you lower. The tops are mildly flattened with a recessed bottom area for external cable routing. Haven't crashed with them yet so I can't attest to durability but they look great on my 2013 Scott CR1.
