DESCRIPTION

ProX DT swiss 350SL Carbon Gravel Wheels - Premium Gravel Bike Wheelset For Racing

DT Swiss 350s road hubs are developed to be reliable and simplified. The reliability is achieved by the simultaneous engagement of the ratchets which result in larger contact area.

The simplified end-caps design makes it possible for tool-free disassembly and easy maintenance. The cost of DT swiss 350 hubs are much lower than DT swiss 240 and DT swiss 180 hubs.

Carbon gravel wheels built with DT350 hubs are of great performance and affordable price for racing.

Cyclocross and gravel carbon wheels demand versatility and durability. ProX gravel bike carbon wheels are designed with 26mm inner width rims, which is suitable for gravel tires with size 700*37C-50C. The 40/45/50mm rim height options strikes a compelling balance for mixed-terrain adventures. 


Rim Height Options: 40mm vs. 45mm vs. 50mm

Choosing the right rim height depends on riding style and terrain:
40mm: Ideal for technical, unpredictable terrain. The lower profile prioritizes agility, weight savings, and crosswind stability. Perfect for riders tackling steep climbs or twisty singletrack.
45mm: A versatile middle ground. Balances aerodynamic gains compared to 40mm rim , and with moderate weight. It suits riders mixing paved gravel terrain.
50mm: Maximizes aerodynamic efficiency for fast-paced gravel races or rolling terrain. Slightly heavier on weight but offers noticeable speed retention on smoother surfaces.
