Summary

The Specialized Tarmac is celebrated as a top-tier race bike, offering a blend of lightweight design, aerodynamic efficiency, and responsive handling. It's praised for its comfort and versatility across various terrains, making it a favorite among competitive riders. The inclusion of disc brakes in newer models has been highlighted for improving braking performance without sacrificing speed.

Pros
  • Lightweight and aerodynamic design

  • Responsive and precise handling

  • Comfortable for long rides

  • Improved braking with disc versions

  • Versatile performance across terrains

Cons
  • High price tag

  • Firm ride quality on rough surfaces

  • Some models may feel twitchy due to short wheelbase

Key Quotes
The Tarmac Disc Pro delivers the high performance you’d expect from the top-of-the-line S-Works Tarmac, at a much more affordable price.
Bicycling
Specialized claims the new S-Works Tarmac SL6 is substantially lighter, slightly more comfortable, far more aerodynamic than the previous generation, and the handling has mellowed just a bit as well.

Specialized Tarmac SL5 Comp Disc review

Jul 2018 · Guy Kesteven

Sort the cockpit and the Tarmac is a well balanced, responsive, race-style all-rounder. Buy if you want to cruise the flats and dance up the hills with added disc brake control on the descents

Highs
  • Naturally lively and responsive race all-rounder with fatigue-reducing forgiveness

Lows
  • Slightly soft at full power and the short stem makes for a cramped and twitchy feel
