977 XC SIZING With the 979 and 977 MTB models, made with LOOK carbon technology, discover the pleasure of riding off the beaten track The 977, with its 27.5″ wheels is recommended for short to average height mountain bikers and has the particular features of being very responsive when accelerating and having great handling. Technologies HM UD Carbon Technology HM: High Modulus. « High-end » fibers. Their stiffness is very elevated, on average double that of HR fibers. The HM fibers permit more rigidity without the added weight. LOOK bicycles are made with either HM 3K or 1.5K fibers, the latter having a finer weave, therefore lighter (ie. a 1.5 fiber =1500 threads in 1 fiber). The unidirectional fiber sheets, also known as UD: The carbon fibers on the sheet are all orientated in the same direction. A tube or any other carbon fabricated product, is made up of a succession of layers, one of the principal fabrication secrets and one of LOOK’s strengths, lies in the choice of fiber orientation for each layer. This allows a very precise control over the desired behavior for each manufactured piece. For over 30 years, LOOK has developed a unique expertise and a vast experience of combining different types of fibers to achieve specific desired properties. We know how to vary the parameters of carbon composition to give a product a desired behavior. DCSC Concept The LOOK DCSC2 concept (Dual Comfort and Stiffness Concept 2) is the union of all the factors leading to the the successful creation of the ideal compromise between stiffness and flexibility. The headset, for example, is high enough for a comfortable riding position, and the carbon chain and seat stays adopt a flatter in shape. This flattening of the tube section is done without diminishing their diameter and boosts the lateral and vertical stiffness by 25%. The vertical flexibility is also improved in the process. 27.5’’ Wheels For its hardtail line, LOOK proposes two different wheel sizes: 27.5″ or 29″ wheels. LOOK MTBs with 27.5″ wheels are recommended for those who are looking for comfort, stiffness, and handling. Using this wheel size lightens the bicycles overall weight making for a more dynamic ride. These sized wheels are particularly suggested for people of shorter to average height.
