Shimano Dura-Ace/XTR RT-MT900 Ice Freeza Technology road and mountain bike disc

Disc brakes are becoming the norm. In competition or intensive use, rapid heat dissipation is essential. The Shimano Dura-Ace RT900 disc is based on the technical characteristics of the XTR mountain bike version, which offers high-level performance. On the road, very high speeds can be reached. At the bottom of a hill, the disc must not overheat. The Ice Technologies Freeza brake disc technology allows heat to dissipate quickly to maintain braking performance on long descents. The high-temperature paint on the disc also improves heat dissipation.We recommend mounting 140mm at the front and rear for maximum weight savings and/or 160mm front/rear for optimal braking, or 160mm at the front and 140mm at the rear for a combination of lightness and efficiency.lt;span>
