Thank you for contacting us. The seat tube measurements listed for the 2018 AnyRoad Advanced 1 are correct. The near 2” difference in just the seat tube measurement severely changes the overall geometry of this bike. By significantly upgrading the frame material, from CoMax Composite to Advanced Composite, the AnyRoad frame was redesigned for optimum performance. The 2018 AnyRoad Advanced is a completely different bike from its 2017 CoMax counterpart.
The use of Advanced Composite for the 2018 AnyRoad has allowed fine tuning for best-in-class power transfer and comfort, while shedding overall weight. We hope you are able to locate a dealer nearby with an AnyRoad Advanced in stock to test ride.
