Polygon Siskiu T8 (Purple/Black)
8994981039659-2025
A full-suspension trail bike for riders who want one machine to confidently tackle both climbs and technical descents, with a FOX fork and 4-piston brakes for genuinely aggressive terrain.
Overview
The Siskiu T8 is engineered with progressive geometry, modern suspension travel and a build that lets you push into more aggressive terrain while remaining versatile enough for everyday mountain-trail use. A FOX 34 Rhythm fork handles the front end with genuine trail-focused performance.
A Shimano SLX 1x12-speed drivetrain delivers smooth, simplified shifting with reduced maintenance, and powerful Tektro HD-M745 4-piston hydraulic disc brakes provide superior stopping power when the terrain gets technical. A dropper seatpost allows quick saddle height adjustments while riding, matching the bike's progressive intent.
It's built for riders who want one bike that confidently handles both the climb up and the technical descent down.
Why You'll Like It
Progressive geometry built for confidence
Progressive trail geometry gives a stable, confident ride on steep descents without sacrificing climbing manners.
A trail-tuned fork
The FOX 34 Rhythm provides ample travel and genuine control on rough terrain, not just a token suspension fork.
4-piston stopping power
Tektro HD-M745 4-piston hydraulic disc brakes give superior stopping power for genuinely technical descents.
SLX-level shifting
The Shimano SLX 1x12 drivetrain delivers smooth, simplified shifting with meaningfully reduced maintenance versus a 2x setup.
A dropper post for real technical capability
Quick saddle height adjustments while riding let you adapt instantly as the terrain changes.
Who Is It For?
The Siskiu T8 suits riders who want to confidently tackle both climbs and technical descents on one bike — a true all-rounder built to push into more aggressive terrain.
In India, that suits riders exploring genuinely technical trail networks in the Himalayan foothills or Western Ghats, where a single ride often mixes demanding climbs with rewarding, technical descents.
It also suits a rider stepping up from a shorter-travel or lower-spec trail bike who wants a genuine step up in fork performance and braking power.
Good to Know
The FOX 34 Rhythm fork rewards a bit of setup time — dialing in air pressure and rebound to your weight makes a real difference on technical terrain.
The dropper post is operated by its own lever at the bar — get familiar with the actuation point before a technical descent so it becomes second nature.
