All-new Marin Rift Zone trail bike gets shreddy-er, from 29er to kid’s models

The 2023 Marin Rift Zone alloy mountain bikes are all-new from the ground up, but they call it an evolution, not a revolution. The goal was to simply take one of their most popular models and make it more capable without changing its playful character.

Travel is bumped up 5mm to 130mm in the rear, with longer 140mm forks on all full-size bikes, and 130mm forks on junior bikes. The geometry was modernized with a 1º steeper seat tube and 0.5º slacker head angle, and 430mm chainstays across the board.

This aligns the model across 29er, 27.5, and Junior (24/26) models…giving them each the same kinematics, look, and feel for all wheel sizes. It makes for great “adult” bikes, and even better kids’ bikes.

The new “Rifty” has a slightly higher initial leverage ratio and larger volume canister for good small bump compliance. A very linear overall curve keeps it predictable throughout the travel. Anti-squat is about 112% at 30% sag, with virtually flat anti-rise to avoid brake jack.

It all adds up to suspension good enough fro Martha Gill to take the win at the 2022 Crankworx Rotorua Dual Slalom on this bike.

The bikes fit up to 2.5″ tires, shown here with the Maxxis Assegai 29×2.5″ that come stock on the top model.

What about the carbon models?

For now, the carbon Rift Zone bikes, which were added to the line in 2019, carry over unchanged, still with 125mm rear travel and 130mm forks. But you can probably see where this is headed.

Upgraded Junior models for the kids

Marin Rift Zone 26″

Geometry is a bit different for the smaller bikes, with a 65.5º head angle, 76º seat angle, and 425mm chainstays.

The Junior and base level “1” come with a proprietary bolt-in 9mm rear axle to keep costs low, but both are upgradeable to a standard Boost 148×12 boost thru axle on both, too. Yes, Boost on a kids bike, which makes it easier to find parts since non-boost MTB hubs are getting harder to find.

2023 marin rift zone JR 24-inch

Marin Rift Zone JR 24″

26” and Junior (24″) bikes’ X-Fusion Velvet forks get a damper that’s tuned for lighter riders so it’s more compliant and actually works for smaller riders. The JR gets 155mm cranks, 26” gets 170mm cranks. MSRP is $1799 for both.
