185毫米盤(pán)式制動(dòng)器

Assembly file of a floating rotor bicycle disc brake. It's the same, six point mount IS2000 standard design (44mm PCD) as the previously uploaded 203mm disc. Suitable for rear wheel mount/fit on downhill bikes. For a smaller size (160mm) the spider center section would require a complete re-design, however, no one uses 160mm discs on a downhill bike, so, the work would be just for fun, no practical gain.
