The NS AGX i25
The NS AGX i25 wheelset embodies FSA’s commitment to supporting riders who seek the roads and trails less traveled. As part of the AGX line—crafted specifically for Adventure, Gravel, and Cyclocross riding—this artisan-built wheelset is constructed entirely by hand, utilizing FSA’s advanced metal alloy technology and state-of-the-art manufacturing processes. With a 4-pawl aluminum freehub compatible with Shimano 9-11 speed, SRAM 9-10 speed, and SRAM XD 11-12 speed drivetrains, this wheelset excels in durability and versatility, handling diverse gravel terrain with ease. Weighing in at just 1,780 grams per pair (29”), the NS AGX i25 features a 25mm internal width and tubeless-ready design, making it an outstanding choice for riders who need both performance and resilience on unpaved routes.
Testing
During our gravel testing, the NS AGX i25 performed exceptionally well across varied surfaces, from loose, rocky trails to compacted dirt roads. Although this wheelset is tubeless compatible, we opted to use tubes, which still provided impressive grip and control on rougher sections. The wheelset’s construction allowed us to maintain low tire pressures to enhance traction and comfort over bumpy terrain. Its robust build handled impacts and vibrations with ease, underscoring FSA’s commitment to durability and high performance in challenging off-road conditions. Each ride reinforced our confidence in the NS AGX i25 as a reliable companion for any gravel adventure.
In conclusion
The FSA NS AGX i25 wheelset is a standout choice for gravel riders looking for a dependable, high-quality wheelset that thrives on rugged terrain. With its strong construction, smooth engagement, and versatile performance, it’s an ideal addition to any gravel setup. We’re pleased to have it as part of our build, and it’s well-equipped to handle the challenges of our gravel adventures ahead.
