Cara Naik-in Average Speed Sepeda MTB Kalau sudah Rasa ke-Entengan Polygon Siskiu D7

Polygon Siskiu D7 saya sempat di modif pakai chain ring 32t dan sproket belakang 11-36t

siskiu D7 2017

Untuk average speed dengan kombinasi seperti ini hanya dapat kisaran 10-12km/h (ya orang nya juga sambil jalan juga menaik kan kekuatan fisik)

Nahhhh

Karena ingat aslinya MTB siskiu D7 old pakai chain ring dual speed (36t & 22t), sproket belakang 11-36t.

Akhirnya saya putuskan mengembalikan dia ke fitrahnya.

Alhasil average speed saya naik 2-4km/h, lumayann. Kok bisa? saya bandingkan dengan trek yang sama persis dan kondisi cuaca hampir sama, jam juga mirip2 lah.

Full spec Polygon Siskiu D7 2017

This year the lightweight frame continues with its 120mm, linkage driven single pivot suspension system that has minimal pedal bob. The D7 frame, like the D6, has been improved. Polygon have added a single piece linkage which has resulted in reduced lateral flex in the rear triangle and improved the linear movement and performance of the shock. Furthermore, the frame continues to internally route all gear cables, resulting in a frame with really clean lines.

The D7 does feature upgrades over the D6, mainly come in the form of branded components. Rockshox now supply their Rockshox 30 Silver Solo Air fork and its a superb addition to this bike – as the forks are known for their linear, plush and predictable feeling

The Suntour EpiXon rear air shock features a hydraulic speed lockout and rebound adjust so you can customize the sensitivity to each and every trail you encounter.

As a nod of the head to performance, it is now a double chain ring crankset, reducing the weight and unwanted duplication of gear ratios, commonly found in triple ring cranksets.

The crankset features a hollowtech spindle, external bearings, and with Shimano Deore now branding the crankarm, you can rest assure that there is the Shimano guarantee of compatibility with the Shimano Deore cassette and Shimano Deore XT rear derailleur. The clutch on the rear derailleur continues to be a well-deserved asset on the bike, removing any unwanted chain slap.

Keen observers will note that Shimano hubs have now also been spec’d on the bike, these free rolling hubs add to the reliability of the entire package.
