天下一穴2代: textured front blocks and rear ridges

Images were selected by position and quality; individual human review is pending.

Codex checked this text against the source; independent human review is still pending.

Ride Japan's 天下一穴2代 weighs approximately 456g, up from about 400g for 天下一穴1代. Firmness is similar to the earlier model, with softness around 3. Oiliness is slight and odor somewhat stronger than before. The tested package included the unit and 1 sachet of lubricant; accessories may vary by batch. Composition was not verified.

Channel changes

The front retains transverse-ridged blocks but reduces the dotted blocks found in the earlier model. The rear now uses continuous elongated ridges instead of the earlier difficult terminal narrowing. Front fine-friction feedback resembles the predecessor, with looser contact and some empty space improved by air removal. Rear feedback is continuous over smaller contact areas and stronger than at the front. 四重螺旋, 八重螺旋 and 金之螺旋 serve as ridge-design references, not confirmation of identical construction.

Within stronger-feedback models, the source prefers the revised rear to the predecessor. Individual perception varies; a high score does not establish universal fit. Bending changes texture contact direction. The source's explicit procedures are not treated as instructions here.

Durability and cleaning

Removing the terminal narrowing simplifies cleaning compared with the earlier model, but the two-layer material should not be inverted. Layer separation is a stated possibility that could shorten service life, not damage observed in this test. Powder-maintenance compatibility was not verified.

All scores are out of 5: headline recommendation 5; experience 4 graphically, with audience-specific written recommendations of 5 for stronger-feedback preferences, 4 for texture exploration and 3 for sensitive first-time users; durability 4 graphically; ease of cleaning 3.5 in the text; intensity 4 at the front and 4.5 at the rear; tightness 3 graphically, above 3 after air removal; softness 3 graphically. Audience recommendations are not substituted for a single formal experience score.
