Break the Wind, Hold the Speed

Modern gravel riding has redefined its boundaries. It’s no longer merely about surviving the trail—those technical backcountry miles have paved the way for a new era of speed, defined by fast-rolling hardpack, swift paved link-ups, and wide-open dirt. As distances stretch and the pace quickens, the core challenge shifts. On fast, open terrain at speeds above 30km/h, aerodynamic drag becomes the primary barrier to performance.

To solve this equation, we developed the Light Bicycle Aero Gravel wheels. By pairing deep carbon rim profiles with wide gravel tires, the AG wheels help you hold speed on fast roads without giving up the toughness you need off-road. Leading this lineup is our all-new deepest gravel option to date: the Light Bicycle AG58 disc, engineered alongside the highly versatile AG48 disc.

Ride The Pro Trend: Maximum Volume, Unrivaled Speed

Sharing the exact same "Wider is Faster" DNA, both the AG58 and AG48 feature an ultra-wide 35mm internal width engineered to maximize wide-tire performance. This increased air capacity enables lower operating pressures that absorb off-road chatter, turning power-sapping surface vibration into pure forward drive. Driven by professional race trends at iconic events like Unbound Gravel—where top contenders now favor 45mm, 50mm, and even wider tire setups—this design slashes rolling resistance, filters out rider fatigue, and inspires absolute cornering confidence over loose dirt. For high-speed sectors, the 58mm AG58 holds relentless momentum across rolling terrain, matching 50C–55C+ tires to minimize turbulent drag. For dynamic routes, the versatile 48mm AG48 combines aerodynamic efficiency with sharp, responsive handling on technical climbs and in gusty crosswinds. Whichever profile you choose, both wheelsets back their performance with uncompromising strength, officially passing extreme 105J impact tests.

AG58 VS. AG48: Match Your Route Profile

Gravel conditions vary widely, and selecting the right depth depends on your local terrain and riding style.

Model	AG58 Disc (58mm)	AG48 Disc (48mm)
Primary Focus	Top-end aero gains & high-speed momentum	Balanced versatility & lighter rotational weight
Best Terrain	Fast hardpack, rolling dirt, flat gravel races	Steep climbs, technical singletrack, unpredictable terrain
Handling Characteristics	Settled at speed; requires active control in gusts	Predictable steering response in sudden crosswinds
Rider Profile	Speed-obsessed racers and fast group riders	All-rounder endurance riders and mountain explorers

Which Path Will You Take?

Choose AG58 if:

Your typical routes feature fast hardpack, open gravel, and long paved sections.
You regularly participate in fast gravel events, all-road races, or long breakaways.
You are experienced in handling deep-section wheels and comfortable making subtle adjustments in crosswinds.
You value aerodynamic top-end speed and momentum over absolute minimum weight.
You need a custom 28-hole drilling.

Choose AG48 if:

Your daily rides consist mostly of steep, low-speed technical climbs or rocky backcountry trails.
Your routes are frequently exposed to severe, unpredictable mountain gusts or heavy bikepacking loads.
