- Stiffness evidence
- De Rosa attributes additional rigidity to the high-module carbon frame and fork, oversized tubes, elliptical bottom-bracket area, and dropped stays; qualitative manufacturer evidence only, with no numeric protocol or independent exact-frame result
Current exact-family evidence establishes drivetrain options. The retained card does not select one, no controlled complete weight was found, and De Rosa currently publishes incompatible 30 mm and 32 mm clearance maxima.
Buying context
Before buying, verify Selected exact build, complete BOM, and controlled complete-bike weight; One reconciled manufacturer maximum tire-clearance value; Current mainland purchase source authority, warranty route, and final checkout conditions.
About DE ROSA
Price record and sources
These sources support this model page; individual claims retain the confidence of their cited source.
Official exact-model or exact-platform page used for image identity. Mainland price, stock, configuration and warranty evidence remain separately unresolved.
Current exact-family manufacturer page identifies a roughly 900 g carbon frame, an elliptical bottom-bracket area described as providing greater stiffness, Shimano 105 Di2 2x12, and a 32 mm tire maximum. The retained mainland card does not expose its selected complete build.
Current manufacturer white paper for the exact 838 platform states maximum tire clearance of 30 mm, conflicting with the live product page claim of 32 mm.
Current official regional material documents a Campagnolo Chorus New 838 build, confirming that the family is offered in more than one drivetrain configuration.
Current mainland index identifies a New 838 Shimano 105 HDB option but does not expose a controlled complete weight or enough configuration detail to select it for the retained card.
Exact-model manufacturer launch article identifies a high-module carbon frame and fork, oversized down and top tubes, an elliptical bottom-bracket area and dropped stays. Its lower-weight and greater-rigidity statements are qualitative manufacturer claims without a numeric protocol or independent measurement.
