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."

SHIMANO CUES 1X11 DRIVETRAIN
Boasting a massive 11-50T 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.

ROCKSHOX RECON FORK
One of the most underrated performers in the RockShox range. It packs a massive punch with its air spring design, 120mm travel, adjustable rebound, and compression dials for fine-tuning.

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.

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.

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.
