ดิสโรเตอร์ XTR, SMRT99, IceTech, 180mm. (Center Lock) Shimano XTR SMRT99 IceTech Center Lock Freeza Brake Rotor (180mm) Shimano XTR RT99 IceTech CL Disc Rotor Nobody puts more thought into brake rotors than Shimano, and the SMRT99 XTR Race Centerlock Rotor is proof of that. The hybrid steel and aluminum construction saves weight and manages heat buildup. Even better, it's been topped off by Shimano's lightweight and userfriendly Centerlock hub rotor interface. Now, you may be wondering what IceTech construction actually means, or then again, why it matters? Basically, IceTech rotors consist of two stainless steel braking tracks that are bonded to an aluminum innercore. XTR SMRT99 Ice Tech rotors providing consistent braking performance through energy control, using revolutionary stainless steel alloy 3layer 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. Features: FREEZA rotors allow the alloy core to extend out from the braking surface as a fin to providing added cooling Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion Rotors are durable lightweight and rigid, using the proven Shimano CentreLock system giving increased strength and security with an easy setup Precision cut and drilled braking surface improves pad clearing in muddy conditions while aiding cooling under high load Large alloy spider is a highly rigid and lightweight support for the rotor surface Super polished braking surface gives excellent braking performance Average weight 126g for 160mm Specifications: Diameter: 140mm, 160mm, 180mm, 203mm Compatibility: Shimano Centerlock hubs Attachment Type: CenterLock Material: Aluminum Recommended Use: Mountain biking A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on DuraAce and XTR products). ช่องทางการติดต่อ ลูกค้าสามารถสั่งซื้อได้ที่ 1.www.thaibikeshop.net2.https://www.facebook.com/thaibikeshop.net 3. กดเพื่อดู Line: xxxxx4. โทร กดเพื่อดูเบอร์โทร xxxxxx095 หรือ กดเพื่อดูเบอร์โทร xxxxxx7105.หรือมาเลือกรับสินค้าที่หน้าร้านนะครับ ร้านอยู่หน้าสถานีรถไฟสามเสน ถ.เทอดดำริห์ (แผนที่ครับ)Searh ใน gooale map ว่า thaibike หรือ thaibikeshopร้านไทยไบค์ ไทยไบค์คลับhttps://goo.gl/maps/a8ukyUUt9VP2อ่านเพิ่มเติม
