2021 Specialized Allez vs 2020 OPEN MIN.D.
The M is the OPEN MIN.D. size closest to your 54 Specialized Allez. 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 OPEN MIN.D.
Compared with the Specialized Allez in 54, the OPEN MIN.D. in M places the top of the head tube 10 mm lower and 7 mm further back, relative to the bottom bracket. Its wheelbase is 13 mm shorter, which can contribute to quicker direction changes.
