Official ROAD CORSA page; GIRDER sells by direct inquiry and no mainland China marketplace listing was verified. See docs/research-girder-range-inventory-2026-10-24.md for related generations kept separate. Two XHS posts are CORSA family context only: a 2025 bike-store post naming 7120 carbon without generation or wheels, and a 2026 used listing with Tiagra 4720 and a 105 crank whose original or modified package is unknown; neither changes this build's specification or price.

About GIRDER
GIRDER (格拉德) is sold in China by 苏州格拉德自行车科技有限公司, a Kunshan company recorded in a public directory as established on 2015-01-27. The company's own site says it licensed a British brand, tracing it to the 1977 founding of the Edinburgh Bicycle Co-operative and to partners in Manchester, with China authorization in 2014. We found no independent evidence for that origin or licence, so it remains a company claim. A 2016 Biketo article calling GIRDER a domestic brand was published under GIRDER's own byline, not as independent reporting.

GIRDER CORSA 7120 carbon road bike store post (2025-04)
A bike-store post titled as a value carbon GIRDER CORSA road bike states only '7120' equipment and full-carbon construction. Both official CORSA builds use Shimano 105 R7120 mechanical 2×12 on a carbon frame, so this post cannot distinguish the NEW 2025 T47 generation with 50 mm carbon wheels from the earlier press-fit generation with alloy wheels. No price, size, wheel package, weight, clearance or shell standard is stated. Two captured comments only ask the price and about the frame; no answer was captured. Value-claim wording is not accepted.
GIRDER CORSA used listing with Tiagra 4720 and 105 crank (2026-04)
A condition-qualified listing offers a GIRDER CORSA carbon drop-bar road bike with a Shimano Tiagra 4720 group, a 105 crankset, hydraulic disc brakes and carbon wheels, with shipping offered and the price left negotiable. It does not say whether this is an original GIRDER package or a modified bike, and it names no frame generation, size, weight or clearance. It is not a specification for either official R7120 CORSA build. Subjective ride, shifting, braking and lightness praise is not accepted.
