Description

YOUR RIDE, YOUR RULES

The Polygon Siskiu D7 SE is the perfect full-suspension mountain bike for riders of all levels. Whether you're new to the sport or seeking a playful and efficient bike, the Siskiu D7 SE delivers. With 120mm off travel, a durable frame, and modern geometry, it effortlessly handles everything from cross-country loops to technical descents, providing a confident and enjoyable ride for all.

VALUE MEETS PERFORMANCE

The Siskiu D7 SE is designed to conquer climbs with its wide-range 1x drivetrain and efficient pedaling platform. It's also equipped with a dropper post for added maneuverability on the descents, giving you the confidence to tackle technical terrain and flowy trails. The Siskiu D7 SE delivers a capable and affordable ride with quality air suspension and modern geometry.

A TRUSTED BRAND

Polygon is a factory-direct brand with over 30 years of experience crafting high-performance bikes at competitive prices. Vertically integrated manufacturing ensures quality and cost savings. Their mountain bikes have been tested on the world stage at events like Redbull Rampage and the World Cup circuit, boasting a 5-year frame warranty for peace of mind.

INDUSTRY REVIEWS

"Whether you're just getting into the sport or upgrading to your first full-suspension bike, we feel this is one of the best values out there. The Siskiu D7 performs much better than we expected, with a slick aluminum frame, modern trail riding geometry, and quality components like a dropper post—all at a budget-friendly price."

ONE-PIECE LINK

Sometimes simple is better! The linkage-actuated single pivot offers active and progressive suspension making for a supple ride on technical sections and a playful ride on flow trails, while the one-piece pivot bridge reduces flex and saves weight.

SUNTOUR RAIDON BOOST FORK

With extensive adjustability options, including air pressure, rebound, and compression, riders can fine-tune their suspension to perfectly match their riding style and terrain.

ROCKSHOX DELUXE SELECT+ SHOCK

The DebonAir air spring offers easy air adjustment to match rider weight and riding style and impressive suppleness. It features external rebound and compression adjustment for on-the-fly fine-tuning, and the ability to tune progression with volume spacers.

DROPPER POST

Featuring 150mm of drop for smaller frames and 170mm for larger frames, a dropper post allows riders to quickly lower their saddle for improved maneuverability and control on descents.

SHIMANO DEORE 1X11 DRIVETRAIN

Boasting a massive 11-51T cassette, rivalling the range of many 1x12 systems. Enjoy the simplicity and reduced weight of a 1x setup, plus smoother shifting and improved chain retention compared to traditional 2x drivetrains.

Assembly

Your bike needs minor assembly before riding; use the tools and videos included.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.

Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
