Product details

IN STORE PICKUP OR LOCAL DELIVERY ONLY

Whether you're exploring singletrack at Hydraulink Trails or climbing the fire roads around Knox Mountain, the Marlin 6 Gen 3 is built to help riders level up their trail skills. Its updated, slacker frame geometry improves control on descents, while a RockShox Judy fork smooths out rough terrain and tubeless-ready Bontrager Kovee wheels reduce flats and rolling resistance. A 10-speed Shimano CUES LINKGLIDE drivetrain delivers smooth, durable shifting, and an internally routed dropper post lets you move your weight back with confidence as the trail gets steeper.

KEY FEATURES

Frame: Alpha Silver Aluminum frame with internal derailleur, brake hose, and dropper post routing, rack and kickstand mounts, and 135x5mm ThruSkew

Fork: RockShox Judy, coil spring with preload and TurnKey lockout, 100mm travel, wheel size matched to frame size (27.5"/29")

Drivetrain: Shimano U6000 10-speed shifter with a Shimano CUES U6000 GS rear derailleur, LINKGLIDE LG300 11-48t cassette, and 30T U4000 crankset

Brakes: Shimano MT200 hydraulic disc brakes, 160-180mm Shimano RT26 rotors depending on size

Cockpit: Bontrager alloy handlebar (size-specific width and rise), Bontrager Comp stem, and a TranzX JD-YSI34 dropper post (100-150mm travel depending on size)

Standout feature: An internally routed dropper post comes standard, paired with tubeless-ready wheels and a RockShox Judy fork — genuine trail-progression spec at this price point

WHO IS THIS FOR?

The Marlin 6 Gen 3 suits riders progressing beyond an entry-level hardtail who want a dropper post and tubeless-ready wheels for more confident, technical descents on trails like Hydraulink or Knox Mountain. Its slacker geometry and upgraded suspension make it especially appealing to riders who've outgrown a basic mountain bike and are building real trail skills.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

HOW TO SET UP

Our team will set up your RockShox Judy fork's coil spring preload for your weight, and get your tubeless tire setup dialled in on the Maxxis tyres for local trail conditions. We'll also set up your TranzX dropper post and handle contact point fit — saddle height and handlebar reach — so your pedaling and descending position both feel natural. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.

Q2: Is the Marlin 6 Gen 3 right for Hydraulink or Knox Mountain?
Yes — with a RockShox Judy fork, tubeless-ready Maxxis tyres, and a dropper post for more confident descents, the Marlin 6 is well suited to the singletrack and fire roads found at Hydraulink Trails and Knox Mountain.

Q3: How do I set up the suspension on the Marlin 6 Gen 3 for my weight and riding style?
