BikeRadar describes the Roubaix SL8 Expert as having a plush Future Shock front and a stiffer-feeling rear. This is qualified qualitative operating evidence for the Roubaix SL8 platform, not a numeric frame test or proof that every Tiagra component build feels identical.
Frame stiffness status
Qualified qualitative platform evidence: BikeRadar describes the Roubaix SL8 Expert as having a plush Future Shock front and a stiffer-feeling rear. This supports an operating stiffness/compliance distinction for the Roubaix SL8 platform, not a numeric frame test or proof that every Tiagra component build feels identical; compliance evidence is kept separate from any numeric frame-stiffness claim.

The exact Tiagra page publishes the complete 2x10 drivetrain and a 9.46 kg size-56 production-painted weight basis. The dated China catalog offer is CNY 15,990 alongside CNY 17,990; a 2026-09-24 official-homepage search result repeated this product card, but the exact China detail-page recheck exposed no price, selected option, stock, or purchase control. Stock, offer duration and final dealer checkout remain unverified, so no observed_price is assigned. BikeRadar adds qualified qualitative Roubaix SL8 platform evidence, not a numeric Tiagra-build test. See the B26 recheck and B71 result for route and price provenance.
