Look ZED 3 Crankset
AERODYNAMIC CRANKSET, ULTRA LIGHT AND RIGID
The LOOK ZED 3 crankset is the latest development in LOOK carbon technology applied to transmission. It picks up the already exceptional characteristics of the ZED 2 whilst being more aerodynamic due to a carbon spider that covers both chainrings. This carbon shield is 100% monobloc with the rest of the crankset and includes the fixing points for both chainrings. The chainrings are thus fixed inside the crankset and it is necessary to remove the crankset from the frame to perform this quick, simple operation. The ZED 3 has been developed to be both the lightest and most rigid possible. It achieves the record weight of 360 grams (spider axle cranks but excluding chainrings), which makes this aerodynamic road crankset the lightest on the market. It is extremely rigid. The weight/stiffness ratio is by far the best on the market.
NEW THREADED CARBON AXLE WITH SELF ADJUSTING RINGS
Fitting, removal, maintenance and adjustment of the crankset are eased due to a new axle that allows removal of the crankset whilst leaving the 2 bearings in place in the frame. Automatic play compensation is also included: tightening the external ZED retaining ring automatically removes play. For yet more weight and accuracy gain the carbon axle is directly threaded (no additional aluminium rings).
COMPATIBLE WITH 110 & 130 BCD DOUBLE & COMPACT
The ZED 3 crankset's carbon spider accepts double (130 mm BCD) or compact (110 mm BCD) chainrings whose external surface is completely flat (this is the surface in contact with the spider). For the ZED 3 we recommend using LOOK chainrings whose design and rigidity have been developed to ensure perfect consistency. The special chainring bolts are delivered with the crankset.
To arrive at its exceptional characteristics the ZED 3 crankset uses MONOBLOC manufacturing technology. The two cranks plus the axle form a single carbon part moulded at very high pressure. The cohesion of the different carbon layers and the fibre orientations are optimised. The ZED 3 crankset has hollow cranks and the construction is not made heavier by any aluminium reinforcement. The axle has a special shape that allows the crankset to be inserted in the frame using a very precise sequence of movements.
