With 180 mm of travel, the bike is ready for both climbing and also descent.
Yes, this is not a prototype, but a bike that ready for daily riding and also racing. With radical geometry, the Square One EX9 looks very different than other bikes. This radical geometry looks complicated, mostly on the suspension system used, the Naild R3act Suspension. The one makes the bike different is the rear triangle. 
Talk about Polygon Square One EX9's geometry, sure it is really interesting as the bike adopts different approach on the tubing. The tubing is really unusual than others, the bottom bracket also unusual and different, but it said that this bottom bracket offers better impression. The company even claims that the rear shock is effective when the bike is riding the steep uphill section.

This performance can not be separated from the suspension system, the Naild R3act Suspension.

Polygon said that the Naild offers very interesting and out of the box suspension system, which is they called genius.

Look Closer: Calibre Bossnut - A Budget Trail Bike

When we're new to mountain biking and find that good bike has crazy price (most of them), a good hardtail can be good first decision before upgrading along with skills. But among the mainstream and popular brands, there are some good brands that build good bikes, and if someone wants to be anti-mainstream, underrated companies can be the option. Calibre Bossnut, really a budget trail bike anyone can buy.
A budget bike does not always the bike performs not good or equipped with second-class parts (for some, second-class parts is meaningless). So, what about the Calibre Bossnut's performance? First, let's check the appearance, in general. The Calibre Bossnut frame layout offers nice geometry for trail riding and have been tested in UK.
This is a trail bike, so the company puts a 130 mm travel for 27.5 wheelset, which is really nice combination as trail bike. Made of aluminum material, the frame has 67 degree of head angle, slack enough and that's reasonable reach to get best positioning when riding the bike. The bike also has large space to accomodate big tires.

What about the parts then? 

This a budget trail bike is using good parts from good companies. For the suspension system, the Calibre Bossnut is using Rockshox suspension, the combination of Sektor fork and Monarch shock. For some, these suspension maybe second-class parts, but they both are good suspension and perform well. For the drivetrain, when most bikes are using 1x11 or 2x11 speed, the Calibre Bossnut still using the Shimano Deore 2x10 speed, combined with Shimano Deore brakes. Is this cons? It depends on the users.

On the wheels, the bike is using the combo WTB rims 27.5 inch with Shimano Deore hubset, and laced with WTB Vigilante 2,30 tires. Ritchey will complete the steering parts, starts from handlebar and stem. The manual seatpost also stock from Ritchey, with WTB saddle. 

With little modification and upgrades, this budget trail bike the Calibre Bossnut will ready to blast most of trail riding, all mountain or even the enduro. Just add dropper post and put a shorter stem, the Calibre Bossnut is reall budget trail bike monster.

The first one, DVO Onyx is a downhill fork, with 203 mm of travel and the brand says that the Onyx is the bigger version of Diamond, their enduro/all mountain fork. But that's reasonable because the Onyx uses the same compression bladder. The Onyx has high-low speed compression damping, rebound damping, air volume adjust and their Off the Top adjuster. The OTT allows the riders to increase or decrease the suppleness of the fork. Sounds awesome, but the Onyx DC is priced about $1,700 which is pretty good if compared with Rockshox or Fox suspension.

The Beryl is basically the Diamond, but with lesser feature; minus external adjuster. It has 35 mm black stanchion, which seems now getting popular, and 15 mm Axle. The Beryl is using the simpler damper which called the D2. On the market, the Beryl will be priced at $750, way cheaper than the Diamond, and will face to face with Fox Float 34 Grip and Rockshox Yari.

Production Privee Shan Nº5

Most people known the company as the steel hardtail maker, with their popular Shan, Shan GT, and another. But, the company just makes a big surprise few times ago when they build a full suspension bike prototype. And the show continues, they really build a full suspension bike and showing it in Taipei Cycle Show 2017, with the Production Privee Shan Nº5.
With the carbon trend on mountain biking industry, the steel bikes still there with their fans. It may heavier than the carbon, but surely the steel bike will be last longer than the carbon. For the Production Privee, this Shan Nº5 is really inspired by their hardtail Shan with more development in various parts. And the result, a 138 mm of travel suspension bike, all around bike, more fun, simple, and reliable. 

The Shan Nº5 is adopting the single pivot with Fox Shock DPS on the rear shock. The main pivot has the same size with the BB shell, pretty big and different than others. As all around bike, the Shan Nº5 accepts the fork from 140 mm to 160 mm of travel. The Shan Nº5 also compatible with 27.5 or 27.5+.  For the fans, the bike is available in frame only option to allow fans to build as they want, but it comes with Fox DPS Shock, about 1,899 Euro.
