The reviewer shares his 4-5 year experience with the Dengfu R01 Ultralight frame, covering the ordering process, a detailed physical inspection, weight measurement, and a CT scan analysis of the carbon layup and potential voids.
AI Summary
Pros
- Good price ($550 for frame set, $619 total with shipping/fees)
- Flawless and fast email communication with the seller
- Quick shipping (about 1.5 weeks to Europe)
- Frame was well-packaged and protected
- Frame fits the reviewer perfectly (58cm for 193cm height)
- No major complications over 25,000 km of use
- Never had any creaking issues with the bottom bracket
- Frame weight is roughly below 1000g for an XL size with some components still attached, close to the claimed 850g ±50g
- Fork weight is 336g (with bearing race attached)
- Bottom bracket has an aluminum shell molded into the frame, which the reviewer believes contributes to high tolerances and plain faces
- Most tube areas (down tube, head tube, top tube, seat tube) show nice carbon layup with no or minimal voids
- Some mating areas (e.g., seat tube/top tube junction, brake caliper mount) look well-connected and reinforced with no critical voids
- Overall, the reviewer is pretty happy with the frame apart from the bottom bracket area
Cons
- Bottle cage nut corroded and became stuck in the frame, a minor complication
- Bottom bracket is BB30, which requires adapters for Shimano's 24mm axle, which the reviewer finds not ideal and would prefer BB86
- The reviewer states the stiffness is 'not that great' due to the BB30 design
- Maximum tire clearance is 25mm (28mm does not fit)
- CT scan reveals voids in critical mating areas: significant voids in the lower part of the bottom bracket area, some voids in the chain stay/bottom bracket junction, and larger voids in the seat stay merger region
- The bottom bracket area is described as 'not optimal,' 'not very well made,' with 'lots of voids' that decrease stiffness
- Some voids are present in the drive-side chain stay (a normal tube area where they shouldn't be)
- Internal cable routing through the chain stay can be tough due to folded carbon layers
- The reviewer concludes the build quality is 'not the highest quality' and notes that voids at mating areas were expected, though not all are critical
Key Points
- Frame ordered in September 2017
- Ridden for roughly 25,000 km over 4-5 years
- Raw carbon matte finish, no custom paint
- Full internal cable routing
- BB30 bottom bracket
- Standard 27.2mm seatpost
- Size: 58cm (fits reviewer at 193cm)
- Max tire clearance: 25mm
- Frame weight claim: 850g ±50g
- Actual measured weight: below 1000g for XL with headset bearings, derailleur hanger, and bottle cage attached
- Fork weight: 336g (with bearing race)
- Bottom bracket features a molded aluminum shell
- CT scan used to inspect carbon layup and voids, with voxel sizes as small as 0.3mm for detailed regions
- Critical mating areas inspected: bottom bracket, chain stays, seat stays, top tube, seat tube junctions
