2019 Specialized Shiv TT vs 2020 Cervélo P-Series

The 48 is the Cervélo P-Series size closest to your XS Specialized Shiv TT. We match frame stack and reach. This is a geometry comparison, not a fit recommendation; stem, spacers, handlebars and saddle setup also affect your riding position.

What changes on the Cervélo P-Series

Compared with the Specialized Shiv TT in XS, the Cervélo P-Series in 48 places the top of the head tube 3 mm lower and 6 mm further forward, relative to the bottom bracket. Its wheelbase is 19 mm longer, which can contribute to stability at speed.
