Tyee Signature Spec 1

The Tyee 5 leverages Propain’s direct-to-consumer model to deliver high-end componentry at competitive prices. The current lineup highlights two distinct Signature Spec builds that cater to different budgets while maintaining aggressive enduro intentions.

The Signature Spec 1 serves as the entry point, utilizing a Marzocchi Bomber Z fork and Bomber CR coil shock to provide reliable, supple suspension performance. It features a SRAM Eagle 70 Transmission for precise electronic shifting, Magura MT5 brakes with 203mm rotors, and Crankbrothers Synthesis Enduro Alloy wheels.

Stepping up to the Signature Spec 2 brings significant upgrades to the suspension and rolling stock. This build features a RockShox ZEB Ultimate fork and Vivid Ultimate rear shock, offering extensive damping adjustments for riders who want to fine-tune their setup. The drivetrain moves to a SRAM GX Eagle Transmission, while braking is handled by SRAM's powerful Maven Silver four-piston calipers on 200mm rotors. It rolls on a durable DT Swiss EX 1700 wheelset. Both builds are equipped with a OneUp V3 dropper post, ensuring reliable saddle height management across the range.

Reviewers consistently praise the Tyee 5 for its remarkable climbing manners, largely credited to the PRO10 suspension's high anti-squat values. Testers noted a "near-complete lack of pedal bob" (Enduro MTB), making the bike feel taut and responsive under power. This efficiency means riders rarely need to reach for a climb switch, even on long fire roads or technical singletrack ascents.

However, that firm pedaling platform introduces a distinct tradeoff on descents. With an air shock, the rear end can feel slightly harsh over rapid, successive hits. Testers observed that the bike tends to "skim over the tops of the bumps rather than consume each and every one" (BikeRadar), rewarding an active riding style over passive plowing. Swapping to a coil shock dramatically alters this character, improving small-bump sensitivity and turning the bike into an "aggressive rocket ship" (Theloamwolf) that tracks much better through rough rock gardens.

Handling is generally viewed as stable and balanced, though the long wheelbase on the 29-inch models requires deliberate input in tight switchbacks. While it may not be the most agile option for slow, janky terrain, the supportive mid-stroke gives the Tyee a lively, poppy feel on faster, flowing trails, allowing riders to easily generate speed out of corners and rollers.
