Showroom + Workshop: The FSA K-Wing AGX Carbon Handlebar, FSA ST AGX VAS Stem, and the FSA SP AGX Flowtron 100 mm Dropper Post for maximum comfort on the gravel bike.08.02.24 09:13 180

To improve comfort on harder or longer gravel rides, we're upgrading our Merida Silex gravel bike with a dropper seatpost, a vibration-damping stem, and the "High-end Super-light plays all Integration and Ergonomics tricks" gravel handlebar from the AGX line-up by FSA.

The AGX components by FSA were specifically developed for Adventure, Gravel, and Cyclocross and are distinguished not only by their specialized ergonomics but also by their robust construction.

We chose the following parts:
FSA K-Wing AGX Carbon Handlebar in 440 mm (Link to FSA Shop)
FSA ST AGX VAS Stem in 80mm with -6° (Link to FSA Shop)
FSA SP AGX Flowtron 100 mm Dropperpost in 27,2 mm (Link to FSA Shop)

FSA K-Wing AGX Carbon Handlebar in 440 mm

FSA's revamped flagship of their road bike handlebars is now fully compatible with the Aerodynamic Integrated Cable Routing (ACR) as well as Semi-Integrated Cable Routing systems. This means that all cables can either be completely or partially routed internally, while still having the option to route them externally.

In addition to improved ergonomics for gravel riding with a short reach and outward-facing handlebar bends, the full carbon handlebar is also supposed to feature a structurally reinforced clamping area. As a result, it not only withstands the higher forces of the disciplines Adventure, Gravel, and Cyclocross, but is also compatible with the company's own vibration-damped stem.

Note on the FSA width specifications (center-to-center): The K-WING AGX width of 44 cm (440 + 49 mm = 489 mm) corresponds approximately to the specified width of 42 cm of other manufacturers, whose gravel handlebars are more flared out. For example, the Easton EC70 AX at 42 cm (420 + 68 mm) achieves a nearly equivalent total width of 488 mm at the handlebar ends.

FSA ST AGX VAS Stem in 80mm with -6°

The newly developed gravel stem offers high vibration damping, achieved through a 360-degree isolation of the handlebar. An elastomer encloses the clamping area of the handlebar and reduces shocks to the rider's hands, wrists, and arms by up to 47% better than a conventional stem. The FSA ST AGX VAS comes with three differently damping elastomers for "Race," "Sport," and "Comfort.

Attention: Special caution is required with carbon or lightweight handlebars, especially if they are equipped with holes for internal cable routing in the central clamping area. If necessary, consultation with the respective manufacturer should be sought. In any case, we advise against tightening the internal stem clamp excessively.
The FSA K-WING AGX Carbon handlebar has been reinforced in the clamping area accordingly.

FSA SP AGX Flowtron 100 mm Dropperpost

A technical highlight is the light and compact FSA Flowtron seat post, now also available in the road bike-typical diameter of 27.2 mm. Included in the delivery is a mechanically actuated remote lever, which can be easily mounted on the drop handlebar and comfortably operated while riding. Additionally, the response behavior can be adjusted in three stages using the actuator spring integrated in the post.

The one-piece stanchion-clamp-head unit features a sealed lightweight metal cartridge, a sliding bearing system with brass guide pins, and a particularly low clamping height.

Workshop

Since the nipple of the internal cable is hooked onto the post, only remote levers compatible with clamping the bare cable end can be used. Therefore, Shimano's mechanical GRX levers with the dropper post pivot function are not suitable.

However, we have found a method to attach the cable to the mechanism of the Flowtron post without a nipple and without modifying any parts of the post. All that is needed is a metal sleeve, a small clamping nipple, and a Bowden cable that is long enough to use this technique.
