In this comprehensive guide, we’ll dive deep into what makes the URS 01 LT ONE a top choice for gravel enthusiasts, covering its specifications, features, real-world performance, and more.

What Sets the URS 01 LT ONE Apart in the Gravel Bike Market?

The gravel bike segment has exploded in popularity, with cyclists seeking machines that can handle everything from smooth pavement to bumpy dirt paths. The BMC URS 01 LT ONE stands out as a full-suspension gravel bike, blending cutting-edge technology with a sleek aesthetic. Manufactured by BMC Switzerland, a brand renowned for high-performance bicycles, this model is part of the URS (UnReStricted) lineup, emphasizing exploration without limits.

At its core, the URS 01 LT ONE is built around a premium carbon frame that weighs approximately 1,050 grams, contributing to an overall bike weight of around 9.5 kg in a medium size. This lightweight construction ensures efficiency on climbs and speed on flats, while the integrated suspension system adds a layer of comfort that’s rare in traditional gravel bikes. Unlike rigid frames, the URS 01 LT ONE incorporates 20 mm of front travel and 10 mm of rear travel, hidden within the carbon fork and frame triangle for a clean, aerodynamic look.

Riders who prioritize comfort during long rides will appreciate how this setup absorbs vibrations and impacts, making it ideal for multi-day bikepacking trips or challenging gravel races. The bike’s geometry is tuned for stability, with a slacker head tube angle (around 70 degrees) and a longer wheelbase, providing confidence on descents without sacrificing agility on technical sections.

Key Features and Specifications of the URS 01 LT ONE

To truly understand the appeal of the URS 01 LT ONE, let’s break down its key components and technical specs. This bike is engineered with precision, using high-end materials and innovative technologies to enhance every aspect of the ride.

Frame and Construction

The heart of the URS 01 LT ONE is its URS 01 Premium Carbon frame, designed with Tuned Compliance Concept Gravel technology. This ensures the frame flexes just enough to absorb road chatter while maintaining stiffness for power transfer. The Gravel+ Geometry features a 74-degree seat angle, 425 mm chainstays, and a 69 mm bottom bracket drop, striking a balance between comfort and responsiveness.

Internal cable routing keeps the aesthetics clean, and the frame includes provisions for racks, mudguards, and up to four bottle cages, making it bikepacking-ready. There’s even internal dynamo routing for lights and charging on extended adventures. The down tube protector guards against rock strikes, and the chainstay guard reduces noise and wear.

Suspension System: Micro Travel Technology (MTT)

One of the most innovative aspects of the URS 01 LT ONE is its Micro Travel Technology suspension. The front uses an MTT Suspension Fork with a coil spring and hydraulic damper, providing 20 mm of travel (effective around 12 mm with sag). A lockout dial allows riders to firm up the suspension for pavement efficiency.

At the rear, an elastomer insert in the compliant rear triangle delivers 10 mm of travel, paired with a D-shaped carbon seatpost for additional flex. This setup excels at damping vibrations, with tests showing a 22% reduction in front vibrations on big hits and 25% on high-frequency chatter compared to benchmark bikes. However, the rear suspension may feel less effective on larger impacts, transmitting about 37% more vibration than some competing seatposts.

Drivetrain and Braking

The URS 01 LT ONE comes equipped with a SRAM Force eTap AXS HRD groupset, featuring wireless shifting for seamless operation. The 1×12 drivetrain includes a 38T chainring and a 10-52T cassette, offering a massive 520% gear range. This allows for easy climbing on steep gravel inclines (lowest gear around 20 inches) while maintaining high speeds on tarmac.

Braking is handled by SRAM Force eTap AXS HRD hydraulic discs with 180/160 mm rotors, providing powerful, modulated stopping power even in wet or muddy conditions. The mullet setup (Force front, X01 Eagle rear) ensures durability on rough terrain.

Wheels and Tires

Rolling on CRD-400 SL carbon wheels (40 mm depth, weighing about 1,600 grams), the URS 01 LT ONE offers low rotational weight for quick acceleration. These tubeless-ready rims are paired with 40 mm WTB Raddler tires, which provide excellent grip on loose surfaces thanks to their knobby tread and tan sidewalls.

Tire clearance is up to 42 mm (or 45 mm in some configs), allowing for customization based on terrain. While this is sufficient for most gravel riding, it might limit options for those seeking ultra-wide tires for extreme off-road use.

Cockpit and Finishing Kit

The cockpit features an Easton EA70 AX handlebar (440 mm width) and a BMC MSM02 stem (80 mm length), promoting a comfortable, upright position for long rides. The saddle clamp is integrated, requiring some effort to adjust, but it’s compatible with 27.2 mm dropper posts for added versatility.

Performance Review: How the URS 01 LT ONE Handles Real-World Riding

Real-world testing reveals why the URS 01 LT ONE is hailed as one of the best gravel bikes available. Reviewers note its exceptional capability on rough terrain, where the suspension maximizes traction and comfort, allowing riders to maintain speed over bumps that would slow down rigid bikes.

On pavement, the bike feels light and fast, easily sustaining speeds above 30 km/h without the suspension holding it back. The stable geometry inspires confidence on descents, with the longer front center and shorter stem aiding control. Vibration damping is a standout feature, reducing fatigue on long rides—front vibrations are notably lower than on bikes like the Open WI.DE.

In comparisons to mountain bikes, the URS 01 LT ONE bridges the gap effectively. It offers better comfort and traction than pure gravel bikes like the Canyon Grizl but falls short of full MTBs like the BMC Twostroke on highly technical trails due to limited tire volume and suspension sensitivity. The suspension shines on isolated hits but can feel overdamped on consecutive bumps, with a noticeable top-out noise.

For bikepacking, the URS 01 LT ONE excels with its mounting points and stable handling under load. The wide gear range handles loaded climbs, and the lockout feature optimizes efficiency on smooth sections.
