The 989 RS MTB is the ideal choice for X-Country competition or long marathon distances. Its 29 » inch wheel size provides excellent traction and and makes clearing obstacles easier.
Featuring a HM (High Modulus) carbon monobloc frame, the 989 RS is a lightweight mountain bike that retains optimum rigidity. Its integrated A-STEM assures very precise handling. The chain and seat stays have been designed to filter a maximum amount of vibration. This comfort is enhanced by the use of the integrated E-POST R5 seatpost.
HM 3K Carbon Technology
HM: High Modulus. « High-end » fibers. Their stiffness is very high, 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, and therefore lighter (ie. a 1.5 fiber =1500 threads in 1 fiber).
For over 30 years, Look has developed a unique expertise and a vast experience that permits them to combine different types of fibers to achieve certain desired properties. We know how to vary the parameters of carbon composition to give a product a desired behavior.
The A-Stem is part of the LOOK DIRECT DRIVE concept, namely an optimization of all of the cockpit factors with the goal of providing a maximum amount of stiffness to enhance handling precision.
The A-STEM stem is made of forged aluminum, is invertible, and available in 2 different angled versions in a choice of lengths by increments of 10mm: +/- 5mm from 80 to 130mm and +/- 15mm from 80 to 120mm.
E-Post R5 Seatpost
LOOK’s carbon seatpost, the E-POST, is integrated and particularly comfortable thanks to its 3 elastomers that absorb shocks and vibrations.
The Ti version permits an aft saddle adjustment of – 15mm to -45mm as measured from the seat tube axis. Weight: 213gr.
The E-POST is also available in an R5 version which offers a fore/aft adjustability of + or – 5mm as measured from the seat tube axis by virtue of its reversibility (360° adjustable clamp). Weight: 196gr.
The R32 version is invertible and it is possible to adjust the fore or aft position + or – 32mm as measured from the seat tube axis (360° adjustable clamp). Weight: 216gr
Direct Drive Concept
The LOOK « Direct Drive Concept » is the optimization of all the parameters that make up the cockpit. This is notably done through the integration of the stem, as an extension of the bicycle itself, and also by the use of a short and tapered headset with a 1 1/2 inch bottom and 1 1/8 inch top. The total of these factors provide an excellent rigidity that is necessary for an optimal piloting position.
For its hardtail line, LOOK proposes two different wheel sizes: 27.5″ or 29″ wheels. Thanks to the 29″ wheels, LOOK MTBs have the characteristic of making clearing obstacles easier. The grip and inertia are higher and allow riding at a higher speed. The LOOK 29er MTBs are particularly recommended for people of average to taller height.
