Ice-Tech FREEZA
SHIMANO’s ICE TECHNOLOGIES has realized the ultimate clad rotor, incorporating aluminum fins for enhanced heat control. With an increased surface area for heat dispersion, the rotor achieves a 50°C reduction in heat. This in turn generates a 20% increase in braking force durability and a 20% longer pad life.
Center Lock System
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.

Aku maticu prosim obsahuje balenie? S vnutornym ci vonkajsim ozubenim? Potrebujem tento kotuc dopredu aj dozadu a predpokladam ze vpredu na 15mm osku musi byt vonkajsie ozubenie a dozadu na 12mm osku vnutorne?
Zdravim, z obzka vyplyva, ze ma matica vonkajsie ozubenie. Na mojom starom bicykli znacky Trek som mal vonkajsie ozubenie aj v predu aj v zadu, takze problem s tym nepredpokladam.
Dik, len som cital v inych vasich prispevkoch ze obrazky su len ilustracne preto som si chcel byt isty. Objednal som radsej jednu vonkajsiu maticu zvlast keby prisli vnutorne, uvidime.
Kotuce prisli a obsahuju iba maticu s vnutornym ozubenim.
To je zvlastne, ked som ich bral ja, tak boli naopak, je mozne, ze shimano zmenilo. Mrzi ma teda dezinformacia. prijmite nase ospravedlnenie.
Ved v pohode, nic strasne sa nestalo len teraz potrebujem tu vonkajsiu maticu lebo to tam neviem namontovat
Dobry deň,chcem sa opytať či mate kľuč CL na takyto typ kotuča resp,na kotuče z vonkajšim dražkovanim?aka je cena a či je dostupny?
ďakujem
Dobrý deň,
Na maticu s vonkajším drážkovaním sa používa kľúč na stredové zloženie Hollowtech II a teda napr. https://www.mtbiker.sk/shop/servis-a-trening/naradie/stahovaky-na-stredy/shimano-tl-fc32-kluc-plochy-na-misky-hollowtech-ii.html
kotuc predavate s maticou ako na obrazku (vonkajsie utahovanie)?
Dobrý deň,
áno, kotúč je s touto maticou.
dakujem za info ...spolieham sa teda na to a objednavam 2ks
dobry den, dnes mi boli kotuce dorucene a napriek Vasmu uisteniu nemaju pozadovanu maticu.
Dobrý deň,
spoliehali sme sa žiaľ na informácie od dodávateľa a jeho obrázok k danému produktu. Po prekontrolovaní sme zistili, že skutočne je reálne pribalená iná matica a tak sme obrázok upravili. Ospravedlňujeme sa Vám za nesprávne informácie.
Tovar nam samozrejme mozete vratit na nase naklady, navod ako postupovat najdete u nas na webe - https://www.mtbiker.sk/shop/informacie/vsetko-o-nakupe.html
Dobrý deň,
dá sa ešte kotúč objendať?
Dobrý deň,
bohužiaľ dodávateľ nevie, kedy bude kotúč opäť naskladnený. Môžete si ho zatiaľ pridať do wishlistu.
All the answers to questions about delivery, payment, security, returns, warranty and much else.



The picture is incorrect, the wheels came with a nut with internal teeth. So for the front 15mm axle you need to get another nut with external teeth. Otherwise, great discs, well made.
