Finally in our hands, for an in-depth test, the new enduro “monster” of the Yeti house with which Richie Rude, winning all the special stages of an Enduro World Series race, set a new record last October in Finale Ligure.
The new Colorado endurona is not simply a bigger-wheeled version of the well-established 6” SB27,5. The SB150 was born from a new project that incorporates all the concepts characterizing the Yeti full bikes and reinterprets them in a modern key, improving some details, where possible to improve a dream mtb, and significantly modifying the geometries. We remind you that, in the gravity field, carbon is used more for the design possibilities it offers and for the different dynamic response compared to metal frames than for the weight issue. The full carbon frame of the new SB 150 is the state of the art of fiber manufacturing and was developed by Yeti according to the standards downhill to withstand the heaviest stresses. At the heart of the shock absorbing kinematics, the Switch Infinity system remains unchanged, managing the 150mm of rear travel with its floating pivot in collaboration with the now metric Fox X2 shock absorber. At the front, the travel has been increased to 170mm. An important design work involved the central area of the frame, both as regards the main triangle and the rear end. The bottom bracket, which on the SB6 was placed exactly under the Switch Infinity, thanks to a revolutionized positioning of the pivots on the rear end, is now decidedly further back. Another innovation concerns the anchoring of the shock absorber to the upper pivot link, now no longer direct but connected to a Wishbone shock extension which, in addition to facilitating maintenance operations, has made it possible to find space for the water bottle. The particular "inverted hump" shape of the oblique tube and precisely, the high positioning of the shock absorber, have been designed to place the bottle cage in the traditional position, overcoming a defect of the SB6. The integrated cable passage has been further improved with perfectly connected inlets and outlets and internal guides that facilitate assembly operations.

VERSIONS AND COMPONENTS
The SB150 is offered in two different carbon versions, the Turq Series and the C Series. The T series is more rigid, lighter (- 250gr) and expensive, also due to the particular processing without residues in the internal part of the pipes. The cheaper C Series is offered in two trim levels, GX (€ 5.799) and GX Comp (€ 6.599), both with Fox Performance suspension and Sram GX Eagle groupset, the first with DT Swiss M1900 wheels and Sram Guide R brakes, the second with Dt Swiss M1700 wheels, Shimano XT brakes and Sram X1 carbon crankset. The Italian distributor DSB also offers a variant of the basic GX set-up with chassis "C" but equipped with Fox Factory suspensions at a price of 6.399 euros. The Turq Series frame is sold in three trim levels in addition to the frame kit (€ 4.399) with Fox X2 Factory shock. The X01 Turq (€ 8.299) and X01 Turq Race (€ 8.999) set-ups are equipped with Fox Factory suspensions, Sram X01 carbon crankset, Yeti Carbon handlebars and differ in brakes (Shimano XT 4 pistons the first, Sram Code RSC the second) , wheels (DT Swiss M1700 the former, XM1501 Spline One the latter) and lighter and more refined sprocket / stem cassette for the latter. Finally, the top of the range XX1 Turq (€ 9.999) equips the top of Fox for suspension and dropper, of Sram for transmission and brakes, Dt Swiss for the wheels and Race Face and Ergon for the rest of the components. With a surcharge ranging from 1000 to 1300 euros depending on the version, on the Turq Series you can have the optional carbon wheels.

GEOMETRY
The geometry of the SB 150 has been developed to perform at its best in enduro races. Compared to the SB6, the new SB150 shortens the undercarriage by 9mm which now stands at just 433mm, a rather interesting share for a 29 ”. The central area of the frame, completely redesigned, has allowed the bottom bracket to be moved back considerably, obtaining at the same time a shorter stay and a more vertical seat angle (76,9 ° in the L size tested). The steering angle is more "open" by one degree ... with its 64,5 ° it is among the slackest in the category. The reach of size L in tests of 480mm gives an idea of the front length (815mm the front-center) of this enduro beast which, despite the contained wagon, has an impressive wheelbase length (1248mm). The Race Face Turbine R handlebar of this set-up turned out to be excessively wide (800mm) for our testers ... never mind, in case of purchase, cutting it to a more suitable size is a simple operation.

WISHBONE SHOCK EXTENSION - The shock absorber is not directly connected to the connecting rod but is connected with this extension which, among other things, facilitates disassembly operations.
THE RESPONSE OF THE TEST
The very long reach and wheelbase would suggest a very relaxed riding position but, thanks to the almost vertical seat tube, the short stem (32mm) and the spacers under the stem that raise the handlebar (1075mm from the ground) and bring it closer to the rider, we found the exact same position (saddle / handlebar distance) that we set on our Yeti SB6 in size M. Thanks to the Infinity Switch, the efficiency of the anti-squat pedaling remains excellent, especially in steep sections and broken down where you can always keep an efficient and round pedaling, even when seated, without minimally inhibiting the work of the suspension. In this way, traction losses become rarer events than with any other system we have tried. In the raises standing on the pedals (race mode) it enjoys excellent support and is snappy and performing like few others while in the long rides on asphalt such as transfers, thanks to the very advanced position, we found it a bit tiring. We noticed that, compared to the SB6, the rear suspension is slightly more progressive and gives more support at mid-travel without losing the proverbial feel. This Sb150 impressed us for its speed and stability on the descent on the most technical beaten even though the expectations were obviously high. The ease with which you eat any type of obstacle allows you to choose the most profitable trajectories without breaking down or losing grip. The great work of the rear suspension, very sensitive to small bumps in all compression stages, keeps the wheel glued to the ground even when braking at the limit on uneven surfaces. Like her younger sister SB6, she loves to be ridden with her torso well loaded on the handlebars and is at its best on the steepest, albeit narrow and technical descents.

When the slopes are high, it surprised us by the ease with which it turns in the tightest hairpin bends as long as you load the front well ... in these situations it doesn't really seem to have a 29-inch under your ass with exaggerated travel and bus wheelbase. In the streamlined and not very steep sections, despite being extremely fast, it was a bit cumbersome in the changes of direction. Compared to the old model with 27.5 wheels, the SB150 is undoubtedly less physical and more intuitive… The short wagon makes it playful, easy to understand and to holler from the first meters of the trail. The Fox suspensions deserve a special mention as they work very well in harmony with the frame and provide an excellent front / rear balance making, among other things, incredibly easy landings from jumps. In conclusion, this new SB150 is such a fast racing monster that it will improve the performance of many enduro racers and entertain the most technical and powerful bikers even in bike parks. Despite being a competition mtb, compared to the old SB6 it has improved in terms of intuitiveness and ease of use but, for mountain rides with friends we would undoubtedly opt for the less extreme SB130. Our exceptional tester, multiple Italian enduro champion of the category, with the SB150 beat the kom on one of his home paths on the first attempt ... need to say more ?!
