Ice Technologies

The Shimano RT-CL700 Disc Brake Rotor uses a three-layer brake-track construction consisting of:

Stainless steel outer braking surface
Aluminium internal core
Stainless steel outer braking surface

The aluminium core conducts heat away from the braking track more quickly than a conventional solid-steel rotor. This helps control temperature during repeated braking and extended descents.

Better heat management can provide several practical benefits:

More consistent braking power
Reduced likelihood of brake fade
Improved modulation during sustained braking
Reduced heat transfer into the caliper and brake fluid
Lower risk of pad glazing
Potentially longer brake-pad life
More predictable lever feel on demanding descents

The Shimano RT-CL700 uses Ice Technologies construction but does not feature the additional exposed Freeza cooling fins found on selected higher-tier Shimano rotors.

Optimised 3D aluminium carrier

The braking track is connected to a structurally shaped aluminium carrier. Shimano has designed the carrier in three dimensions rather than using a simple flat spider.

Rotor size guide

140mm

The 140mm Shimano RT-CL700 Disc Brake Rotor is the lightest version and is primarily suited to the rear of lightweight road bikes. It works best for lighter riders, flatter routes and applications where reducing rotational weight matters more than maximising heat capacity.

160mm

The 160mm version is the most versatile choice for road and gravel bikes. It offers stronger heat management and braking leverage than a 140mm rotor without a major weight increase. A 160mm front and 160mm rear setup is a dependable option for heavier riders, hilly terrain and long Australian descents.

180mm

The 180mm rotor provides greater braking leverage and thermal capacity for demanding gravel, cross-country mountain biking, trail riding and lighter e-bike applications. Frame, fork and caliper-adapter compatibility must be checked before increasing rotor size.

203mm

The 203mm version is intended for mountain bikes, e-bikes and heavier riders requiring maximum heat capacity and braking leverage. It is not suitable for every frame or fork, and the manufacturer’s approved maximum rotor size must be followed.

The Shimano RT-CL700 Disc Brake Rotor is ideal for cyclists who want quieter braking, improved heat management and easier Centre Lock servicing without paying for a flagship rotor.

Cleaning and maintenance

Clean the rotor with isopropyl alcohol or a dedicated bicycle disc brake cleaner.
Use a clean, lint-free cloth reserved exclusively for brake components.
Keep chain lubricant, grease, degreaser and silicone spray away from the braking surface.
Do not touch the braking track with oily or contaminated hands.
Inspect the rotor regularly for scoring, cracks, heat discolouration and distortion.
Measure rotor thickness at several points using a suitable micrometer or digital caliper.
Replace the rotor when it reaches Shimano’s marked minimum thickness.
Check lockring torque after initial installation and periodic servicing.
Inspect brake-pad thickness and replace pads before the backing plate reaches the rotor.
Bed in new pads and rotors with a series of controlled stops before demanding riding.
Avoid dragging the brakes continuously on long descents where safe braking technique allows intermittent braking.
Do not cool a hot rotor suddenly with water.
Never attempt to ride with a cracked or severely warped rotor.
Wear clean workshop gloves when handling a new rotor.

Brake-pad bedding procedure

A new rotor must be bedded in to transfer an even layer of pad material onto the braking track.

BikeRadar examined the Shimano RT-CL700 Disc Brake Rotor in video coverage published on 21 March 2026. The publication positioned it as a meaningful update for Shimano 105-level braking systems, drawing attention to the revised appearance, three-dimensional carrier and technology carried over from more expensive Shimano rotors.

Shimano RT-CL800 Ice Technologies Freeza Rotor

The Shimano RT-CL800 is the natural upgrade for riders considering an Ultegra or GRX-level rotor.

Advantages of the Shimano RT-CL800:

Freeza construction provides additional heat-dissipation surface

Excellent option for long alpine descents and racing

Advantages of the Shimano RT-CL700:

Lower purchase price
Same convenient Centre Lock interface
Excellent thermal management for most riders
Available in a wider selection of larger sizes
Stronger value for training and everyday use

The Shimano RT-CL800 is better for weight-conscious road builds and repeated mountain descending. The Shimano RT-CL700 offers better value for regular road, gravel and trail riding.

Shimano RT-CL900 Ice Technologies Freeza Rotor

The Shimano RT-CL900 is the flagship Dura-Ace and XTR-level alternative. It prioritises minimum weight, maximum cooling and premium materials.

Advantages of the Shimano RT-CL900:

Flagship heat-management construction
Lower weight
Premium finishing
Designed for elite competition use

Advantages of the Shimano RT-CL700:

Considerably more affordable
Less costly to replace after wear or damage
Suitable for a broader range of everyday bicycles

Shimano SM-RT70 Ice Technologies Rotor

The Shimano SM-RT70 is a long-established Centre Lock Ice Technologies rotor commonly supplied with Shimano 105, SLX and GRX-level systems.

Advantages of the Shimano SM-RT70:

Proven and widely available
Often less expensive
Strong replacement option for older bikes
Broad compatibility

Advantages of the Shimano RT-CL700:

Newer 3D carrier design
Improved resistance to thermal distortion
Designed to reduce brake noise and rotor rub
More contemporary appearance
Wider size selection

The Shimano SM-RT70 remains a dependable budget replacement, while the Shimano RT-CL700 is the more refined performance upgrade.
