Polygon, the Indonesian Bicycle brand has come out with complete range of 2021 models in India. Polygon’s top end full suspension MTB range is the Siskiu series. We got the opportunity to test ride the Polygon Siskiu D5 (2021) and here is what we thought.
Weight: 14.8 kgs
Usage: Sport/Trail Racing
The Polygon Siskiu D5 (2021) is a fast and compact full suspension MTB packed with performance focused components and is the perfect entry into XC trails.
The Polygon Siskiu D5 (2021) is built on a full Alloy frame. This bicycle is built for cross country and hardcore trail rides on the roughest of terrains. The frame geometry is aggressive yet comfortable to ride thanks to its low and slanting top tube. This low top tube also makes sure there is more standover clearance which makes it safe when riding on bumpy trails.
The Suntour XCM front suspension fork comes with a massive 120mm travel which functioned smoothly during the test ride. The Suntour Raidon Air E2E rear suspension comes with a lock-out which reduced the suspension’s work rate by 80% and thus making it useful for flatter trails.

This XC full suspension MTB which I test rode came with Red as the primary colour with Light Grey as the secondary colour. The gloss finish paint job quality was shiny and the graphics were aesthetic. The internal cable routing for the gears not only made the bicycle look neat but also protected the cables from dirt and damage.
The Siskiu D5 comes in 1 colour variant; Matte Red with Light Grey graphics
The gearing on this XC Trail Full Suspension MTB is handled by Shimano Alivio at the front and rear as derailleurs. This 2x9-Speed derailleurs were smooth and precise in shifting during the test ride and was suited well for trail rides which require constant change in speed. This 2x9-Speed drivetrain gave enough depth of speed for steep climbs on trails and also quick accelerations. The Alivio RapidFire shifters were easy to use and were very responsive.

Shimano’s Hydraulic Disc brakes are top end performance brakes specifically made for fast trails. These brakes on the Siskiu D5 were very responsive and transferred the braking power accordingly in a balanced manner.
The Entity Expert Alloy handlebar was wide and this length helps in keeping the bicycle in full control on fast trail rides and races with sharp corners.

The Siskiu D5 rolls on a pair of Spiderbait 27.5” x 2.25” MTB tires. These tires were heavily treaded with enough rubber compounds to keep the tires safe from smaller punctures. The 27.5” circumference helps with fast rolling on the roughest of trails.
The Entity Void saddle was ergonomically designed specifically for cross country trails with the perfect length and width.

This Full Suspension MTB is built with performance focused components like the full Alivio drivetrain and the powerful Shimano Hydraulic Disc brakes. The 120mm front suspension and smooth rear suspension made the ride less bumpy and in full control on fast trails. Priced at Rs.85,990(as on 12th March 2021) the Polygon Siskiu D5 (2021) is the perfect choice for anyone looking to buy a Full Suspension MTB for trail rides and entry into the world of cross-country XC trails races.
