The Siskiu DSE FS is a big-wheeled mountain bike designed for full-throttle trail riding. Its combination of high standard components and modern trail bike geometry make for an exciting bike that’s kind on the wallet.

How Polygon has managed to build such a loaded trail bike with a truly affordable price tag is beyond us. The Siskiu DSE FS puts the bang into everyone’s buck!

The Siskiu DSE is designed to be ridden fast and furiously on UK trails. Its 29inch wheels and supple air sprung suspension, courtesy of a Suntour Raidon 32 Boost fork and RockShox Deluxe rear shock, iron the bumps out of the trail to keep you charging. Thanks to plenty of reach and a relaxed head angle, the DSE fires down descents like a missile, but it’s a proper climber too. Once you have raised the TransX dropper post and flicked-through the Shimano Deore gears, it’s surprising how easily this bike ascends steep terrain. Grippy Entity Performance tyres and dependable Shimano Deore brakes provide excellent control and reign in the speed with just one or two fingers on the brake levers.

This is a full-suspension bike for beginner and intermediate mountain bikers that are serious about progressing their skills and need a bike that is up to the job.
