Eastway have looked closely on making the Zener's geometry as comfortable and as fast as possible. So whether you are going out for that quick short hack or that long weekend 100 miler the Zener will make sure that you have completed the ride with pace and ease. Shimano 105 Drivetrain Light action Vivid Shifting is just one of many features taken from Shimano's top end groupsets, making the 105 11 speed 5800 groupset a performance option for the masses. The shifters and derailleurs incorporate Shimano's Vivid Shift technology, with a light but positive feel all the way through the 11 speed drivetrain, giving you the gear you want, when you want it, with the minimum of effort. With its two piece hollow axle design, the Shimano Hollowtech II chainset is both stiffer and lighter than a square taper chainset. Using a Pressfit bottom bracket shell also provides increased stiffness and bearing life over standard cartridge units. With 50/34 compact gearing, you can tackle even the steepest climbs with confidence. Shimano Hydraulic Disc Brakes Using the all new Shimano BR505 dropbar hydraulic disc brakes give the Zener the stopping power it needs down the hills. The dual piston caliper ensures even brake wear and a greater performance. Its index shifting mechanism offers the 11 speed drivetrain an economical brake/gear lever but a smooth and elegant gear change. Ritchey Finishing Kit Finishing the Zener off is a set of bars, stem and seatpost from the Comp series by Ritchey in black. Light weight, strong and reliable are the best way to describe this kit. Topping it off Eastway have supplied a custom colourway Fizik Aliante saddle offering maximum comfort.
