The Marin Tam 1 Full Suspension Mountain Bike - 2026 is a fast and capable full suspension bike built for XC laps, long trail rides, and rough terrain. Its Series 4 aluminium frame uses 120mm of IsoTrac suspension to give grip, speed, and control on uneven ground. A 130mm X-Fusion Rezza fork, X-Fusion Rezza rear shock, 65-degree head angle, and microSHIFT Advent MX 11-speed drivetrain give it a strong trail-ready build at a sharp price.
Key Features and Benefits:
- Series 4 aluminium frame with 120mm IsoTrac suspension: The light and strong aluminium frame uses Marin’s IsoTrac suspension platform to help the rear wheel track rough ground with more control. This improves grip and comfort, so the bike feels stable on XC routes, trail loops, and longer rides.
- 130mm X-Fusion Rezza fork: The Rezza fork gives 130mm of front travel and uses a Fine-Cut Damper with three-position control. This helps you tune support for climbs, flat trails, and rough descents, so the bike stays efficient and controlled across mixed terrain.
- X-Fusion Rezza rear shock: The rear shock uses 190x45mm sizing and three-position compression adjustment. This lets you set the suspension feel for the ride, so the bike can pedal well on smoother ground and stay active when the trail gets rough.
- 65-degree head angle: The slack head angle adds confidence on steep or loose sections. It helps the front wheel stay composed at speed, so you can hold your line with more control when the trail becomes harder to manage.
- microSHIFT Advent MX 11-speed drivetrain: The Advent MX drivetrain gives a wide and simple 11-speed setup with a matching shifter and rear mech. This gives dependable gear changes with fewer parts to manage, so you can keep your focus on the ride.
- Tektro HD-M535 hydraulic disc brakes with 180mm rotors: The hydraulic brake system gives strong and steady stopping power at both wheels. The 180mm rotors add control on longer descents, so you can manage speed with less hand effort.
The Tam 1 is built for riders who want a full suspension bike that can handle fast XC riding and rougher trail use without a high price tag. The IsoTrac suspension, slack head angle, dropper post, and tubeless ready wheels give it the control needed for technical ground. The 29" wheel setup and efficient 11-speed drivetrain also help it cover distance with less fuss.
Choose the Marin Tam 1 Full Suspension Mountain Bike - 2026 for a practical mix of speed, grip, and trail control. It gives you modern full suspension performance, solid components, and a ride feel suited to XC routes, local trails, and longer off-road days.

A bike has to go though a Pre Delivery Inspection (PDI Check) prior to despatch, ensuring the bike is thoroughly checked and set up prior to you receiving. This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
