    Strengths:    Suspension, remote seatpost, brakes, lite, excellent climbing/descending, tubeless ready.


    Weaknesses:    Fork, external cables

    Bottom Line:   
    I also wrote the review below but needed to make a couple of corrections (don't do this late at night!) and part of it was deleted when I posted it (?):

    I'm riding the 2015 model that includes the X-fusion 02RLX shock with climb/trail/descend settings and Velvet RL2 fork with lockout. The bike comes with tubeless ready rims/tires so I just added Stan's tubeless valves and sealant and I was good to go. I didn't weigh the bike but figure it's around 29lbs (no pedals or accessories), which is pretty good for a trail bike, especially an aluminum frame in this price range. The 650b (27.5-inch) wheels accelerate quickly and get over roots and rocks well. A 29er might be a bit better over bumpy terrain but the 650b rolls faster and the bike climbs extremely well. The bike's geometry is slack enough and the wheelbase short enough that you will find it handles tight downhills and turns with ease. In the trail or pedal mode the 02RLX shock has very little bob that gets you over rough terrain and up most climbs pretty easily. I have tried the climb mode but find it unnecessary on all but the steepest or smoothest climbs. The open mode is very plush, it has good mid-stroke feel and the shock is progressive for excellent handling on the descents. The Velvet RL2 fork is excellent but I'd like to see more adjustability in keeping with the rear shock. Really, just nit-picking, but it could be more adjustable. Still, a really good fork, simple and reliable. I am 5' 11" and ride a larger, I swapped out the stem (100mm) for 60mm and went with a slightly wider bar . 720mm (stock is 700mm). This made the cockpit a bit tighter and provides better control. I'd also like to see internal cables for better protection but have not had the cables hang up on anything to this point. The brakes are excellent, good control and modulation, lots of stopping power. Not sure how they are on extended downhills but perfect here in Southern Ontario (Canada). The bike also includes a Kind Shock (KS) eTen remote dropper post. It is a simple, cable actuated dropper that is easy to use and has been very reliable. It has just over 100mm of travel so you can drop it out of your way on descents then adjust it to any spot in between for trails and climbs. You know what they say about droppers, once you have one you’ll never want to be without one, and this is a great feature not typically seen in this price range. Overall, a great trail bike, climbs/descends well, and a lot if fun to ride!!!

    Strengths:    The it factor , just feels right . Good geometry , frame design puts your weight where its is supposed to be . The bottom end acceleration from a stop is great , Breaks are very good

    Weaknesses:    I have not found any yet , would have preferred a single gear up front , a shorter stem "personal fitment " , and maybe better tires , but these are all easy upgrades

    Bottom Line:   
    Great bike for the money . Im 160 and 5 8 , bought a medium 17" , I was weight forward with the stock 90 mm stem an seat neutral position . I changed the seat to the rear and bought a 60 mm stem fitment is now tuned to me , bike is "flickable" , turns well , stable , and absorbs log overs and roots very well

    Strengths:    This bike does everything well. It's very stable in the turns, climbs like a goat, outstanding descender.

    Weaknesses:    NONE

    Bottom Line:   
    This bike is outstading for the price. This bike can do just about everything. I use it for trail riding mostly and it does not dissapoint one bit when I use it for downhill. The suspension is great and has surpassed my expectations. It feels very plush on the descents and does not move much on the climbs. There is nothing bad I can say bout this bike. If you want a do it all bike, I definitely would recomend this bike for sure.
