Shimano Dura Ace SM-RT900 アイステック フリーザ センターロックローター
- Dura-Ace SM-RT900 アイステック ローターが、エネルギー制御により一貫したブレーキング性能を提供、革新的なステンレス鋼 / 合金 3 層サンドイッチ構造がライディング中の熱を制御
- ステンレス・アルミ・ステンレスの 3 層クラッド材を採用。ブレーキングで発生する熱はアルミ製のコアから素早く放散され、表面温度は従来型のローターより約 50°C 低くなります。アイステクノロジー採用パッドと併用すると、約 100°C 低くなります。この放熱性能により、あらゆる場面で安定したブレーキングが実現します。
- FREEZA ローターにより合金コアが膨張してブレーキング サーフェスから突出し、センターロック マウント アダプターに対するフィンとなって、さらなる放熱に寄与
- アイステクノロジーが採用されているローターではパッドの寿命が延び、ノイズが低減します。また、優れた放熱性能により、フェード現象が発生しづらくなっています。
- ローターには実証済みの Shimano センターロック システムが使われていて耐久性があり、軽量かつ剛性が高く、簡単なセットアップでさらなる強度と安全性が得られる
- 精密カットされドリリングされたステンレス鋼ブレーキ面が、パッドの泥づまりを防止し、高負荷時の冷却を促進
- 大きな合金スパイダーが高硬度かつ軽量のローター面を支える
- 超研磨仕上げブレーキング サーフェスにより最高のブレーキ性能を実現
- 平均重量 94 グラム (140 mm)
RYAN CHEN I had 6 bolt wheel before so this wasn't an option but now I will surely enjoy the Ice Tech Freeza tech on my downhill. I am a heavy rider at 95kg and I am a downhill specialist so a rotor is a must for my ride
Clifford These offer a worthwhile improvement in braking over Ultegra rotors. An added bonus is that the black finish continues to retain its appearance better, in my opinion, than the silver finish on the Ultegra rotors. Summary - better performance, better long term appearance.
Tim Replaced my Sram rotors with these Dura Ace 140's for use with my Etap HRD brakes and ZIPP 303's, they work really well, no compatability problems with the Sram brake pads. Added bonus they look cool.
Mr Sawyer Good quality item, much nicer looking than the Ultegra item
john Great rotors, work well in all conditions
Vincent Best looking pair of rotors, imo. Went with the 140mm for both front and rear because where I ride (Singapore) is mostly flat.
Nigel G look great and perform better
Mr Goodrich Look great, and just bedding in. No squeal, and braking good.
Stu Howarth Great rotor. New to the world of disc brakes and wow what a difference. Dura Ace look brill too. Can’t wait to race on them!
Robert Great looking rotors that work well too.
Mr Cox Not fitted yet but I’ve used them before and was impressed.
STEPHEN Quality part from Shimano. Easy to install. It looks fantastic on my bike and preforms well.
Mark Fantastic rotors, I have the ultegra ones too and these a big upgrade from those. Powerful braking, sleek and durable looks. Usual excellent service from Merlin too.
Mrs CHARD Purchased these rotors as replacements for my daughters road bike, that she uses for races and training, when she returns to the UK as she is based in Belgium and is a member of a UCI team and they use and swear by these Ice Tech Freeza Rotor. If it's good enough for them it's good enough for us. If your on a budget you could buy the ultegra version. Merlin cycles is great for us because if they advertise it they have it in stock , delivery is quick and fast which is what you want, from a bike shop.
Mr Coelho Jorge Very powerful braking and looks very very good on the bikes instead of the Ultegra ones.
Dean Great rotor and still silent with running the harder pads. Plus look really good.
Richard Didn't like the look of these at first but two years on they have gorwn on me and offer very dependable service. Never had one go out of true without some missap involved. They still shout in very wet conditions - although the 140mm are quicker to howl when wet than the 160mm. Love 'em now.
Michael Great rotors. Squeal free and look awesome too.
Mark Stunning looking rotors, definitely add a touch of class and hopefully performance to your ride.
Mr TOMKINS-GALLIMORE If you want to stop quick, buy these!!
Mr Pape Awesome rotor, black finish looks great and prevents brake fade by a noticeable amount when you use the metal pads as well.
Mr king Awesome, so light and easy to fit with Center lock. Amazing stopping power, well worth the price tag. Completes any bike!
