De Rosa

De Rosa-Compatible Components

De Rosa builds Italian road bikes from Cusano Milanino, balancing racing spirit with a strong design culture. 70 stands out as the flagship road racer when you want an uncompromising, race-first feel for big days. Idol brings a sharper, race-driven road vibe, while 838 keeps things simple and fast for everyday road riding. Framesandgear keeps De Rosa shifting on point with direct-mount hangers for 838 and Idol, plus a rim-brake option.

Framesandgear offers a wide range of derailleur hangers for De Rosa road bikes, covering both standard disc and rim-brake dropout designs. Additionally, the range supports Shimano drivetrain mounting patterns across every model listed. Each hanger uses high-grade aluminium (7075) CNC machined for strength, fit precision, and low weight. Moreover, all products in the De Rosa collection target precise derailleur alignment on road frames, matching the exact dropout standards and Shimano shifting.

Product Types

Direct Mount Derailleur Hangers

Direct mount derailleur hangers attach directly to disc-brake frame dropouts and guide Shimano derailleurs with no separate link hardware. This type improves drivetrain alignment and chain line under shifting load. Furthermore, various colours — including red, black, oilslick, rose, gold, orange, celeste, silver, purple, green, grey, chrome, and blue — reflect bike aesthetics while keeping consistent fit.

Rim Brake Direct Mount Derailleur Hanger

Framesandgear also offers a rim brake direct mount hanger for De Rosa bikes that do not use disc brake frames. This single-product type secures derailleur placement and shift precision on older rim-specific De Rosa frame designs.

Key Features & Advantages

All De Rosa hangers share CNC-machined aluminium 7075 construction manufactured from a single block. Additionally, the components deliver lightweight strength, accurate shifting, and easy installation without adapters. Moreover, the design enhances the fit between the hanger and frame dropout for strong, stable shifting.

Compatibility

Products in this collection fit De Rosa road bike models that use direct mount derailleur hangers, including IDOL and 838 disc brake frames. Also, the rim brake hanger fits De Rosa frames with rim brake dropouts such as the SuperKing, SK Pininfarina, and Orra. Every option matches Shimano drivetrain standards.

Framesandgear also offers complementary parts that pair well with bike builds using other branded parts:

• Universal and brand-specific computer mounts
• Titanium bolts and accessory hardware
• UDH hangers
• Aero-profile mounts supporting various bar shapes

Moreover, these options help maintain a consistent Framesandgear aesthetic and functionality throughout the cockpit.

Shipping & Support

Framesandgear ships worldwide with tracked delivery. Each component is supplied with the required mounting hardware where applicable, making installation straightforward. Technical support is available to confirm compatibility, with replies typically within one business day.
