Polygon Siskiu D5 (Red/Black)
87001209
A full-suspension XC trail bike that climbs like a hardtail and descends even better, built with modern geometry for confident handling on varied terrain.
Overview
The Siskiu D5 is built around an ALX XC Trail frame with a tapered head tube design that reduces flex for excellent front-end control. A slack head tube angle, long reach, and steep seat angle give the bike confident handling whether you're climbing or descending.
Polygon's Faux Bar suspension system provides maximum traction on the rear tire for steady handling on climbs and descents alike, paired with a SR Suntour XCM HLO fork with 120mm of travel. A Shimano 2x9-speed drivetrain delivers smooth, reliable shifting, and hydraulic disc brakes provide dependable stopping power.
It's built for riders who want a trail bike that tackles cross-country terrain with genuine confidence in both directions.
Why You'll Like It
Precise front-end control
The tapered head tube design reduces flex significantly, giving excellent control when the trail gets technical.
Modern geometry built for confidence
A slack head angle, long reach and steep seat angle tackle climbs and descents with equal confidence, not a compromise between the two.
Traction that holds under pressure
The Faux Bar suspension system maximizes rear-tire traction, giving steady handling through rough climbs and descents.
A smooth, dependable drivetrain
The Shimano 2x9-speed setup delivers reliable shifting across the full range of trail terrain.
Confident stopping power
Hydraulic disc brakes give dependable braking regardless of conditions.
Who Is It For?
The Siskiu D5 suits riders who want one bike that climbs efficiently and descends with confidence — genuine cross-country trail riding rather than a bike built for just one direction.
In India, that versatility makes it a strong choice for riders exploring the trail networks around hill stations or the Western Ghats, where a single ride often involves both technical climbs and rewarding descents.
It also suits a rider stepping up from a hardtail who wants the added traction and comfort full suspension brings, without jumping to a dedicated enduro bike.
Good to Know
Regular suspension maintenance keeps the Faux Bar system performing at its best — check air pressure and rebound settings periodically.
The tapered head tube pairs well with a slightly firmer tire pressure up front for maximum steering precision on technical sections.
