The Specialized Tarmac SL8 is renowned for its lightweight design, a critical factor for performance in road cycling. A specific build of the Specialized S-Works Tarmac SL8, equipped with Shimano Dura-Ace Di2, in a 52 cm frame size, has been observed to weigh 6.62 kg (14.7 pounds). This measurement typically excludes pedals and bottle cages, which are considered accessories.
Factors Influencing Tarmac SL8 Weight
The exact weight of a Specialized Tarmac SL8 can vary based on several key factors. While the frame itself is engineered for minimal weight, the overall bike weight is significantly impacted by the chosen components and accessories.
- Frame Size: Larger frame sizes naturally use more material and therefore weigh slightly more than smaller frames. A 52 cm frame, as noted above, is a common mid-range size.
- Component Group Set: Different group sets (e.g., Shimano Dura-Ace, SRAM Red, SRAM Force, Shimano Ultegra) have varying weights. High-end electronic groupsets like Dura-Ace Di2 or SRAM Red AXS are often among the lightest.
- Wheelset: Wheels are a major contributor to a bike's overall weight and rotational mass. Lighter, more aerodynamic carbon wheelsets can significantly reduce the total weight.
- Tires and Inner Tubes (or Tubeless Setup): The choice of tires and whether the bike uses traditional tubes or a tubeless setup can add or subtract a few hundred grams.
- Finishing Kit: Components such as handlebars, stem, seatpost, and saddle also contribute to the final weight. High-end carbon fiber versions of these parts are typically lighter.
- Accessories: Pedals, bottle cages, bike computers, and other add-ons are not usually included in the stated bike weight but add to the ready-to-ride weight.
Specialized Tarmac SL8 Weight Overview
To provide a clearer picture, here's a summary of the reference weight for a common high-performance build:
| Model Variant | Group Set | Frame Size | Weight (kg) | Weight (lbs) | Notes |
|---|---|---|---|---|---|
| Specialized S-Works Tarmac SL8 | Shimano Dura-Ace Di2 | 52 cm | 6.62 | 14.7 | Without pedals or cages |
It's important to note that Specialized designs the Tarmac SL8 to balance aerodynamic efficiency, stiffness, and low weight, making it a competitive choice for various road cycling disciplines, from climbing to flat-out sprints.
