2020 Cervélo P-Series vs 2019 Specialized Shiv TT

The M is the Specialized Shiv TT size closest to your 54 Cervélo P-Series. 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 Specialized Shiv TT

Compared with the Cervélo P-Series in 54, the Specialized Shiv TT in M places the top of the head tube 20 mm lower and 7 mm further back, relative to the bottom bracket. Its wheelbase is 15 mm shorter, which can contribute to quicker direction changes.
