Bianchi Oltre vs Specialized Tarmac SL9: 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 Bianchi Oltre is built as a race geometry frame, the Specialized Tarmac SL9 as a race geometry frame. The Specialized Tarmac SL9 cockpit runs about 17 mm shorter, a noticeably more compact position. The Specialized Tarmac SL9 stack is slightly taller, about 9 mm, which is not enough to change the position by itself.
For the Bianchi Oltre in 47, 50 there is no Specialized Tarmac SL9 size with a comparable position: the range simply does not reach there.
