Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimum Hollow gear construction for optimized rigidity, lightweight and durability Durable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier body HG 12-speed chain compatible Available in 28T/30T/32T/34T/36T
XTR RT-MT900 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 load Large alloy spider is a highly rigid and lightweight support for the rotor surface Super polished braking surface gives excellent braking performance

Customisable Pin Height The height of the pins in the Shimano GR500 Flat Pedals can be set to 3 different heights so, no matter what type of riding you do, these pedals can be customised to suit your needs. Incredible Grip in Harsh Conditions Shimano has taken its popular Saint MX80 pedal as a platform for the GR500 pedals so the shape will feel familiar to many. However, when the pins are set in the highest setting, they are 5mm longer than the pins in the MX80 to provide incredible grip in the harshest conditions.
This is perfect if you wish to run multiple satellite shifters or simply tidy up the routing of your internal Di2 cables. Works with the SM-JC40 external or SM-JC41 internal junction box.
The long pulley cage allows a large gear capacity, so even riding heavily loaded bikes are not a problem.

There aren’t many times a replacement part actually improves your bike but put one on your bike and you’ll wonder why you didn’t install a NINJA sooner. The bearings are housed in an alloy shell and wrapped with plastic and fibre. This fusion of the three materials provides the bearings a solid platform to sit on and extends their lives. A lot of people would be satisfied with this, but they went even further by extending the alloy shell so the right and left sides lock together. This locks the frame, cranks and bottom bracket together and provides unparalleled stiffness.
