Warnings

info single-size-only — Only one size is in stock (52 cm | (28")).
info wheel-material-unknown — Wheel material could not be established.
info wheels-from-build-sibling — bikes-de publishes no wheel row for this bike. The wheelset "DT SWISS G1800 CL frontDT SWISS G1800 CL rear" is read from bikeexchange's listing of the same build and model year (Corratec Allroad C2); every shop in this crawl that names it agrees.
