The current official R20 page identifies the model and publishes an R7 numerical geometry drawing. The drawing does not state linear units. Its current page offers customization and a contact route but no price or exact quote; current indexed catalog results expose prices for other Dengfu models only. Construction, weight, maximum clearance, other standards and package contents remain unverified. Fifty stiffness-specific areas found no controlled numeric result or sufficiently specific independent exact-frame assessment. Batch 35 recheck: Dengfu's current policy provides two years for carbon-frame defects to original purchasers buying directly from Dengfu Sports Equipment Co Ltd; buyer-paid shipping and exclusions apply. This brand policy does not establish eligibility for any specific R20 order or third-party purchase.

The exact R20 Disc Gravel Bike Frame page links the manufacturer image https://dengfubikes.com/static/upload/image/20260502/1777696457547181.jpg, titled R20 Gravel Geometry R7. Visual transcription: columns are SIZE, ST, TT, HT, HA, CA, BB drop, RC, FC, FL, OFFSET, WB, STACK, REACH, STR. Rows: 47/XS 450, 514, 105, 70°, 74.5°, 80, 436, 595.5, 399, 55, 1018.5, 535, 366, 1.46; 51/S 470, 531, 120, 70.5°, 74°, 80, 436, 603.5, 399, 55, 1027, 551, 373, 1.48; 54/M 490, 552, 140, 71.25°, 73.5°, 80, 436, 612.5, 399, 55, 1036, 573, 382, 1.50; 57/L 520, 572, 165, 71.75°, 73.5°, 80, 436, 629, 399, 55, 1052.5, 598.5, 395, 1.51.

Dengfu carbon-frame warranty policy recheck
Current manufacturer policy states two-year coverage for carbon-frame defects for original purchasers who buy from Dengfu Sports Equipment Co Ltd; shipping is buyer-paid. Crash, misuse, neglect and unauthorized modification are excluded. This does not establish eligibility for a specific R20 order or third-party purchase.
Dengfu R20 current official product and price-route recheck
Accessed 2026-09-24. The current exact R20 page calls the product an R20 Disc Gravel Bike Frame and says it can be customized; it exposes manufacturer contact and message routes but no price or exact quote. Current indexed Dengfu store/catalog checks surfaced prices for other frames, not the R20. No currency conversion or other-model price is assigned.
