Burke 20 - Shimano Alfine Di2 11-speed


Once you've tried electronic shifting, you won't want to go back!

Hit the town in style with ALFINE Di2 - a high grade groupset built for the sophisticated urban rider. Along with its premium build quality, ALFINE Di2 brings you finesse, versatility, and effortless operation with an electronic drivetrain. ALFINE Di2 11-speed presents a clean look and a wide gear range that serve to enhance any bike.

The internally geared hub is controlled by mountain-style electronic shifter via wires.  A battery, mounted on the downtube, provides power to the shifter, hub and a small bar-mounted display that indicates what gear you’re in and how much battery is left. When the battery runs low, simply plug in the charger.

The internal geared hub offers a very wide 409% gear range, more than enough for even the hilliest commute. But the real attraction is the simplicity and shifting precision, with no derailleur and cables that frequently need careful adjustment.

Weight of bike: ~ 10.5 kg (23.1 lb) excl. saddle

Gear range: 24.9 to 102 gear inches. See here.

Warranty: Limited Lifetime Warranty on frameset. Standard manufacturer warranty on components.
