MarKnig is an Amazon-direct brand selling a short list of 700c road bikes and 26" hardtail mountain bikes, typically one adjustable frame per model rather than a full size run. Listings target roughly 5'2"–6'0" with seatpost and bar height, not S/M/L. This page has MarKnig’s road and mountain tables. If only one size exists, standover and maximum rider weight on the product page decide the fit.

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.
Height
Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.
Inseam
Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.

Use your height on the Road and Mountain charts on this page (160-183 cm on the road table). When two sizes overlap, cycling inseam and standover pick the side. Then check stack and reach for the exact MarKnig model.
Not safely. MarKnig Road and Mountain charts on this page are separate. A MarKnig One Size (700C) on the road table and a MarKnig 26" Wheel on the mountain table are not interchangeable.
The Road and Mountain charts on this page include One Size (700C) (160-183 cm on the road table). Verify the current MarKnig listing before purchase.
