\n\t\t\t
• \n\t\t\t\tFREEZA rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling
\n\t\t\t
• \n\t\t\t\tIce Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion
\n\t\t\t
• \n\t\t\t\tWith internal lockring housing the magnet necessary for speed sensor function on Shimano STEPS equipped E-bikes allowing frame clearance for wider tyres
\n\t\t\t
• \n\t\t\t\tRotors are durable lightweight and rigid, using the proven Shimano Center Lock system giving increased strength and security with an easy set-up
\n\t\t\t
• \n\t\t\t\tPrecision cut and drilled braking surface improves pad clearing in muddy conditions while aiding cooling under high load
\n\t\t\t
• \n\t\t\t\tLarge alloy spider is a highly rigid and lightweight support for the rotor surface
\n\t\t\t
• \n\t\t\t\tSuper polished braking surface gives excellent braking performance                                                                                          
\n\t\t\t
• \n\t\t\t\tSize options: 160mm, 180mm or 203mm

\n\t\tRT-MT900 Ice Tech E-bike rotors with built in speed sensor magnet providing consistent braking performance through energy control.

\n\t\tThe RT-MT900 uses the revolutionary stainless steel / alloy 3-layer sandwich construction that manages heat while riding. The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round.
