Handlebar
The reviewer mentions the OG-EVKIN HB-1300 Carbon Road Bike Integrated Handlebar as part of the build. They state that OG-EVKIN sent them these handlebars for free, noting they would normally cost around 120 quid. They highlight that these are a fully carbon integrated bar and stem, which allow for internal cable routing and have provisions for mounting a computer underneath.

Dengfu R12 DISC
Frame
The reviewer provides a long-term review of the Dengfu R12 DISC frameset, which they have owned for over a year and ridden for about 5,000 km. They discuss the ordering process, customization, and overall experience. They state it is a direct-to-consumer Chinese brand's flagship frameset at the time of purchase, costing $750 USD. They ordered it raw/unpainted in size 56 to custom paint it themselves. They praise its stiffness and lightweight nature (approx. 1100g for size 56), ease of front derailleur cable setup, and overall solid performance with no squeaks or issues. They note it feels like a 'go-kart' and is very snappy. However, they point out design flaws: the front derailleur hanger limits chainring size to a maximum of 52 teeth, and the claimed 32c tire clearance is inaccurate, with 30c being the realistic maximum. They also mention quirks like bare-bones customer service and packaging, and that some sizes were out of stock. They compare the customer service experience unfavorably to brands like Winspace and Yoeleo, but conclude the frame is worth the price for performance-oriented riders.
