Product Details
Frame/Shock
Series 4 Aluminum Frame – Alpine Trail models feature Series 4 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing, giving riders the highest-end alloy frame that Marin offers.
MultiTrac Suspension Technology – MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks.
148x12mm Boost Thru-Axle
Marzocchi Bomber CR Coil Rear Shock – Coil is back, and not just for gravity riders. Supple on the small bumps with a smooth stroke to eat up rock gardens and big hits, you can rely on Bomber CR coil to lose none of its exemplary performance over the longest descents. Whether you’re looking to breathe new life into your old ride or searching for a rear shock for your new bike you can set and forget, the Bomber CR is your low-maintenance, high-performing coil solution.
Shock Adjustments – Coil Spring Preload / Low Speed Compression / Rebound

Marzocchi Bomber Z1 – The Bomber Z1 is designed for riders ready to get rowdy. Silky smooth travel with the traction and stiffness where it matters.

And so is the Bomber Z1.
