- Tire clearance basis
- Bike Insights' exact 2025 DA54 record reports 32 mm and attributes its geometry data to alvas.bike; the live manufacturer text shows fitted 28C tires but does not state the maximum
- Reference_builds
- Current global Ultegra Di2/Vision SL60 and Australian 105 Di2/Helux R60 builds prove multiple regional trims; neither is assigned to the dated mainland listing
- Stiffness evidence
- No exact-model numeric stiffness test or sufficiently specific independent frame-stiffness assessment was found; regional marketing and general responsiveness impressions are not treated as measurements
The original ALUMS text was a transcription error; current manufacturer and regional records consistently use ALVAS / 爱瓦士. The global and Australian pages publish different complete builds, so the retained CNY 11,439 listing remains trim-ambiguous. A reviewed Australian Ultegra build weighed 8.4 kg with pedals, but that value is not transferred to the mainland listing.
Buying context
Before buying, verify Exact mainland drivetrain, wheels, cockpit and complete-bike weight for the selected listing option; Primary confirmation of the secondary 32 mm maximum-clearance value and meaningful frame-stiffness evidence; Current domestic warranty route and final checkout conditions.
About ALVAS
Price record and sources
These sources support this model page; individual claims retain the confidence of their cited source.
Current exact-model manufacturer page supports the ALVAS spelling and DA54 identity, ALVAS X1 carbon frame and fork, T47 bottom bracket, UDH compatibility, fully internal routing, a current Ultegra Di2 reference build with Vision SL60 wheels, and fitted 700x28C Michelin Power Cup tires. It provides no complete-bike weight or maximum-tire statement, and its component table mislabels FD-R8150 and RD-R8150 as Shimano 105 even though those part numbers belong to Ultegra; the part numbers are retained without repeating the label error.
Current official Australian DA54 105 Di2 page supports a high-modulus ALVAS X1 carbon frame, T47 bottom bracket and fitted 700x28C tires. Its Helux-wheel regional build is materially different from the global Vision-wheel build and is not assigned to the dated mainland listing.
Exact 2025 DA54 geometry record attributes its data to alvas.bike and reports a 32 mm maximum tire width across XS-L. The live manufacturer product text currently publishes fitted 28C tires but not the maximum, so this value is presented as secondary database evidence rather than a direct manufacturer claim.
Index of an exact-model independent video reports an Australian Ultegra/Helux review bike at 8.4 kg with pedals and 7.77 kg after modifications. That regional build does not establish the weight of the dated mainland listing and is retained only to show why weight cannot be transferred between DA54 trims.
