3T Extrema Italia vs Cervélo Áspero: geometry and fit comparison
Matched sizes, stack and reach deltas, and a fit check against your own body instead of guessing from two separate size charts.
The 3T Extrema Italia is built as a all-road geometry frame, the Cervélo Áspero as a race geometry frame. The Cervélo Áspero cockpit runs about 21 mm longer, a noticeably more stretched position. Across matched sizes, the 3T Extrema Italia stack sits about 12 mm taller than the Cervélo Áspero, which generally means a more upright position before spacers.

FAQ
Which has the taller front end: 3T Extrema Italia or Cervélo Áspero?
Across matched sizes, the 3T Extrema Italia stack sits about 12 mm taller than the Cervélo Áspero, which generally means a more upright position before spacers.
Can the same rider take different sizes on these two bikes?
Yes, and it happens often: frame labels are not standardized. Use the matched-size table for geometry, then run the fit check below with your own measurements for each bike.
