The Allez lineup is structured around practical, durable componentry, with a significant performance jump between the base and mid-tier options. Entry-level builds rely on an 8-speed Shimano Claris drivetrain paired with mechanical disc brakes. While functional, these mechanical calipers require more frequent adjustment and lack the outright stopping power of hydraulic systems. Moving up to the Sport or Comp tiers introduces 10-speed or 12-speed shifting alongside hydraulic disc brakes, which reviewers strongly recommend for their superior modulation and lower maintenance.
Across the standard Allez builds, Specialized utilizes its own Axis Sport alloy wheels and 30mm Roadsport tires. These components are robust and tubeless-ready at the rim, but they add considerable weight. To keep costs down, Specialized also substitutes third-party parts like SunRace cassettes and Praxis cranksets on several models, though these rarely impact shifting reliability.
Mechanics and home wrenchers will appreciate the frame's straightforward standards. A threaded BSA bottom bracket, a standard round seatpost, and external cable routing at the handlebar make routine maintenance and fit adjustments simple and inexpensive, avoiding the high labor costs associated with fully integrated cockpits.
