The 675 is the latest edition to the LOOK cycles line up. Born from a completely new manufacturing process: The frame starts draped over mandrels before being placed into the molds for moulding. This technique increases the stiffness of the frame and the overall strength and durability.
For the first time on a road bike, LOOK has completely integrated the stem into the frame design. As well as the aesthetic impact this integration allows them to apply there Direct Drive concept. They achieve this by using a short head tube tapering from 1 1/2“ at the bottom to 1 1/8” at the top and relinquishing the need for spacers. With a shorter head-tube, oversized bearings and a stiffer stem, the whole cockpit is stiffer and more accurate. The A-Stem allows for precise height and length adjustments without having to add spacers.
The 675 is designed in a very sporting spirit whilst being comfortable. The geometry takes this double objective into account and, for example, adopts a fairly high head tube to favor comfortable positions. The fork dampens vibrations, the seat and chain stays use a carbon composition and a shape ensuring a 25 % difference in lateral and vertical stiffness. This is the second-generation DcSc (Dual comfort and Stiffness concept) concept. This concept is based on flattening the tube sections without reducing their diameter. The lateral rigidity is improved, also improving the vertical flexibility.
