Pair of genuine Shimano replacement padsAlloy and Steel back plate using Ice-Tec heat radiation cooling fins with metal sintered braking compoundWill fit Saint BR-M820
Shimano SM-RT64 rotors offer secure and easy set-up with the proven Centre-Lock mounting system,Precision cut stainless steel braking surface improves pad clearing in muddy conditions while aiding cooling underhigh load,Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life,Alloy spider supports rotor surface, increasing rigidity and reducing weight,Comes complete with steel lockring,Average weight for 160 mm rotor with lockring is 153 grams.
Dura-Ace grade RT-CL900 Ice Tech rotors providing consistent braking performance through energy control, using 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,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 Center Lock system giving increased strength and security with an easy set-up.Precision cut braking surface improves pad clearing in muddy conditions while aiding cooling under high loadLarge alloy spider is a highly rigid and lightweight support for the rotor surfaceSuper polished braking surface gives excellent braking performance
Key Features:With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear,The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts,Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold,Sprinter single button shift switches are used to operate the rear derailleur with a tap of the thumb whilst in the drops, one shifter up, one shifter down,Can be used in conjunction with ST-9270 drop bar STI shifters,Shift switches with 100 mm SD-300 series E-tube electrical cables fitted.
Ultegra grade RT-CL800 Ice Tech rotors give excellent performance made from a 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,Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion,Using the proven Shimano Centre Lock system for excellent rigidity and security with an easy set-up,Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life,Large forged alloy spider supports rotor surface, increasing rigidity and reducing weight,Comes complete with alloy lockring.
SM-JC41 E-tube cable junction for internal wire routing,Junction is required for connection of rear mech, front mech, battery, and cable to battery indicator junction box,To be positioned neatly inside frame tubing when connected,Cables sold separately,Reliable and secure water resistant connectors.
Specifications:Group: Alfine Di2,Model: SG-S7051-8,Gears: 8.
Key Features:Di2 charger for the internal battery that will keep your Di2 system shifting,Di2 uses a powerful long-life 7.4V Li-Ion battery: keep it in top condition and ready for shifting with this specific Shimano Di2 charger,1.5 hour charge time,Plugs in directly to the SM-EW90 handlebar junction A,Can also be used for completing firmware updates when linked to E-tube software on your PC.
Features:The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you,Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads,Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever),The use of a single small and discreet internal battery is light weight, efficient and creates a robust and reliable system,One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain),500 times rechargeable life,Internal chip enables system wireless functionality of Bluetooth components,Battery is to be mounted with seatpost or frame/fork manufactures hardware normally inside the seatpost or seat tube/fork steerer,Reliable and secure water resistant E-tube terminals connection,Charging is done via stem junction or handlebar display,Battery weight is 50 grams.
Genuine Shimano replacement part
The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but gives effortless gear shiftsUltegra Di2 uses a fully removable individual cable system from the battery indicator junction box enabling fine tuning with the correct cable length to each component for easy and tidy fitmentEW-SD50 wires are required to connect the junction (either SM-JC40 external or SM-JC41 internal to the rear mech, front mech, battery and to the handlebar battery indicator junction boxEW-SD50 individual wires are available in varying lengths, there is no need (or facility) to cut these cablesReliable and secure water resistant connectors.
