- Complete weight basis
- Manufacturer-listed weight for the 105 Di2 complete bike; size, pedals and weighing method are not stated
- Community model year context
- A promotional XHS post dated 2025-08-15 calls an R7170 Arrow the 2026 model and states 8.4 kg without a size or pedal basis. Equivalence to this official 2025 T47/UDH generation is unverified; the official 8.44 kg reference remains unchanged.
- Used market context
- An XHS listing dated 2025-11-12 asked CNY 7,999 for a used S-size R7170 Arrow with carbon wheels and an integrated bar. Its frame generation is unidentified; this historical asking price is not a current new-bike or exact-trim quote.
The official NEW 2025 ARROW page publishes the complete 105 Di2 build, T800 + T1000 frame and fork, T47 BB, UDH, 8.44 kg claim, geometry chart and a ¥12,800 price. The official route is a direct sales inquiry; no mainland China marketplace listing was verified. This is not the older press-fit T700 + T800 Arrow, which has different sizes, weight and 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.

Brand-authored history. States that GIRDER Bicycle Technology Co., Ltd. was founded in 2015, introduced the British bicycle brand GIRDER and handles design, R&D and sales; positions products in the CNY 5,000–20,000 range. Claims the brand dates back to the 1977 founding of the Edinburgh Bicycle Co-operative, that partners in Manchester created the GIRDER brand, and that authorization to enter China succeeded in 2014. These origin and licensing claims are company-reported and were not independently corroborated. The HTTPS certificate had expired on access; the page was read over HTTP.
GIRDER Arrow used R7170 electronic build listing
A public used-bike listing describes an S-size Arrow with Shimano R7170 electronic shifting, carbon wavy-rim wheels and an integrated handlebar, asking CNY 7,999 including advertised domestic shipping. This is a historical used asking price, not a completed sale, checkout, current new-bike offer or verified stock. No T47/UDH or press-fit identity is shown in the text; the exact generation remains unresolved. purchase source fit-height advice is not accepted. A later public listing posted 2026-06-06 (retrieved by the '格拉德 GLARE' query, not by an Arrow query) repeats the same terms: S size, R7170 electronic hydraulic-disc group, carbon wheels, integrated bar, used condition and CNY 7,999 with advertised shipping. It may be a relisting of the same offer; it is not independent corroboration and does not resolve the generation or show that the bike sold or remained available.
GIRDER Arrow marketed as 2026 with an 8.4 kg claim
A promotional public post markets a purple Arrow as the 2026 model and lists Shimano 105 R7170 electronic shifting, carbon handlebar, wavy-rim carbon wheels, XS/S/M/L sizes, reinforced rear stays and EPS molding, with an 8.4 kg complete-bike claim. Size, pedals, weighing method, T47/UDH identity and price are unstated. A second captured same-day post repeats substantially the same copy; it is not independent corroboration. This may refer to a related or renamed generation, but equivalence to the official NEW 2025 ARROW is unverified. Retain the official exact-page 8.44 kg value and model name; do not convert this rounded promotional number into an owner measurement. Generic strength, handling and noise-prevention wording does not establish measured stiffness or freedom from faults. Captured comments are partial.
