Verticale SLR Shimano Ultegra Di2 R8170

The Verticale SLR is positioned as a premium superbike, and its build ladder reflects that top-tier pricing. The range opens with Shimano Ultegra Di2 and SRAM Force AXS configurations, establishing a high baseline for electronic shifting and hydraulic braking. From there, the ladder steps up to flagship groupsets, offering Shimano Dura-Ace Di2, SRAM Red AXS, and Campagnolo Super Record Wireless.

Wilier provides options with and without power meters on the Force and Dura-Ace tiers, while the Red AXS build includes a power meter as standard. Across the board, the builds prioritize climbing utility, outfitting the bikes with wide-range cassettes and compact or semi-compact chainrings to suit steep mountain terrain.

Nearly all builds roll on Wilier’s in-house Miche Kleos RD 36 carbon wheels, with higher-end models featuring CeramicSpeed bearings. While the frame clears 32mm tires, the stock builds are equipped with high-volume Vittoria Corsa Pro tires that provide a crucial layer of pneumatic suspension. The proprietary V-Bar cockpit and a narrow, custom carbon seatpost—available in zero or 15mm setback options—are standard across the entire lineup, ensuring the core aerodynamic and ergonomic features remain consistent regardless of the chosen drivetrain.

Reviewers consistently praise the Verticale SLR for its highly reactive, traditional climbing feel. The frame’s stiffness translates into a "pulsating surge forward" (Cyclist Magazine) under hard pedaling, rewarding out-of-the-saddle efforts with immediate acceleration. Rather than feeling brittle, the chassis manages to filter out harsh road buzz effectively, with testers noting it feels surprisingly "planted and smooth" (Bike Rumor) over broken tarmac.

Downhill performance is a standout trait. The bike tracks predictably through high-speed, technical corners, possessing enough front-end stiffness to "hold the line without faltering" (Escape Collective) even on rough, off-camber exits. However, this climbing and descending prowess comes with a clear tradeoff on the flats. Without deep aerodynamic tube shapes, the bike requires more effort to maintain high speeds in the valleys compared to modern aero-allrounders.

The primary criticism across multiple reviews centers on the stock Miche Kleos wheelset. Several testers found the wheels slightly heavy for a premium climbing bike, describing them as "underwhelming for the price" (Cyclist Magazine) and noting they lack the lively sensation present in the frame itself. Despite this, the consensus remains that the frameset is an exceptional, highly focused tool for the mountains.
