Urta SLR
The Wilier Urta SLR is a dedicated 100mm-travel cross-country race platform that draws heavily on the Italian brand’s extensive road racing heritage. Introduced for the 2022 model year, it is a lightweight, highly integrated 29er built for modern XCO and marathon courses. Rather than following the industry trend toward slacker, longer-travel downcountry bikes, Wilier keeps the Urta SLR sharply focused on traditional XC efficiency and explosive climbing speed.
The frame utilizes a single-pivot suspension layout with flex stays, driven by a 190x45mm shock integrated cleanly into the top tube area to maximize lateral stiffness. Road-inspired design cues are prominent, including a flat-mount rear brake and the option for a proprietary one-piece carbon cockpit. It is a specialized tool aimed squarely at experienced racers and marathon riders who prioritize power transfer and low weight over downhill forgiveness.

Fit and geometry
The Urta SLR’s geometry reflects its traditional cross-country racing intentions, prioritizing low-speed agility and climbing traction over high-speed descending stability. A 69-degree head tube angle keeps the steering quick and responsive, allowing riders to navigate tight switchbacks with minimal input. This steeper front end is paired with a 74-degree seat tube angle, which places the rider in a forward, aggressive posture that helps keep the front wheel weighted on steep pitches.
Reach measurements are relatively moderate by contemporary standards, sitting at 426mm for a size medium and 453mm for a large. Combined with the standard 435mm chainstays, this creates a compact footprint that feels nimble but requires active rider engagement to maintain control on rough descents.
Fit is heavily influenced by Wilier’s proprietary Urta Bar, a one-piece carbon stem and handlebar combination featured on many builds. This integrated cockpit drops the front end with a -17-degree stem angle, reinforcing the bike's racy, aerodynamic riding position. Because the frame sizing is known to run small, riders between sizes often need to size up to achieve their preferred reach without feeling overly pitched forward.
Builds
The Urta SLR is positioned as a premium race platform, and its build options reflect a high-end, uncompromising approach to component selection. The lineup centers around Wilier’s HUS-MOD carbon frame, which utilizes a flat-mount rear brake to save weight and a simplified linkage design where all pivot bolts use the exact same bearing size for easier maintenance.
Available configurations focus on elite-level drivetrains and suspension. The highlighted Shimano XT Di2 build pairs electronic 12-speed shifting with Fox Factory suspension, utilizing a 100mm Fox 34 Step-Cast fork and a Float DPS rear shock, both featuring Kashima coating and remote lockouts. This build rolls on Miche 966 SPR alloy tubeless wheels wrapped in fast-rolling Vittoria Saguaro tires.
A defining feature of the upper-tier builds is the inclusion of the Urta Bar integrated carbon cockpit, which significantly reduces weight while increasing steering stiffness. While the entry price is high, the value lies in the sophisticated frame construction and the inclusion of specialized components that are ready for marathon or World Cup racing straight out of the box.
Reviews
Reviewers consistently characterize the Urta SLR as an uncompromising climbing specialist that rewards aggressive pedaling. Testers praise the bike's immediate acceleration, with one noting that it "takes off uphill like a rocket" (Magazinebike) when pushed out of the saddle. The suspension kinematics receive high marks for balancing this efficiency with active traction. Even with the shock left open, the rear end remains stable under heavy power, yet testers found it offers "significantly better suspension" (Bike-test) than many direct competitors when absorbing high-frequency chatter.
On descents, the consensus points to a traditional, demanding ride character. The relatively steep front end requires a skilled pilot, as the steering "demands attention to handling" (Magazinebike) and lacks the passive stability of slacker modern alternatives. While the frame and integrated carbon cockpit help "take the sting out of the trail" (YouTube), the bike is not designed to mask rider errors on steep, technical terrain.
Reviewers also highlight a few practical tradeoffs. The stock lightweight race tires prioritize low rolling resistance but offer minimal sidewall protection for rocky trails. Additionally, multiple testers warn that the frame sizing runs small, suggesting riders pay close attention to geometry charts to avoid a cramped cockpit.
