Sizing Comparison

The Liv Langma runs about 5-8mm shorter in reach at equivalent stack heights compared to the Tarmac, reflecting its women's-specific design. A Langma S roughly corresponds to a Tarmac 49-52 in terms of stack, but with noticeably shorter reach. Women transitioning from a unisex bike should expect to feel more comfortable reach-wise on the Langma without needing a shorter stem swap.

Verdict

The Liv Langma is the clear choice for women who want a bike designed specifically for their body proportions-shorter reach, narrower handlebars, and women's-specific contact points come standard. The Specialized Tarmac offers broader size availability and proven race performance but requires swapping saddle and bars for most women riders. Women under 160cm will likely find a better fit in the Langma's XXS, while taller women who prioritize race geometry may prefer the Tarmac's aggressive positioning.
