A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

Key Quotes
The Marin Rift Zone 2 is in the latter category.. A category that happens to be the option for any person getting their first high-end full-suspension mountain bike.
Beta logoBeta
The new “Rifty” has a slightly higher initial leverage ratio and larger volume canister for good small bump compliance.
Bikerumor logoBikerumor
Its geometry and suspension give it a real descending bias, and for that reason I loved it, just keep some money aside to change out the tyres and add a dropper.

Marin Rift Zone XR first ride review - MBR

Nov 2022 · Danny Milner

From a brand steeped in heritage comes a bike that focuses on the stuff that matters: suspension, handling and price. Check out our guide to the best mountain bikes Need to know Alloy trail bike with 130mm travel Revised frame geometry and kinematics over previous generation Updated frame detailing with bespoke protection, SRAM UDH hanger and internal cable routing Three spec levels starting at £1,695 for the Rift Zone 1 (Rift Zone 2 is £2,195) Jr version comes with 26in wheels Sometimes the simplest ingredients make the most delicious dishes. The Spanish turn a tomato, a clove of garlic, some salt, olive oil and a slice of crusty toasted bread into a moorish appetiser that distils the essence of Mediterranean flavours. Italians can effortlessly convert some fresh pasta, a drizzle of olive oil and a shaving of truffle or parmesan cheese into a plate that tastes as good as any Michelin-starred dish. Which brings us to the new Marin Rift Zone, an unassuming trail bike, that’s plain vanilla next to the likes of Trek’s feature-laden Fuel EX and Specialized’s manipulatable Stumpjumper Evo, but has been infused with the flavour of a freshly scraped pod rather than the blandness of a drop of essence. Although outwardly similar to its predecessor, the Series 3 6061 alloy frame has been reworked with new tubing and forgings. The seat tube reinforcement strut has also been replaced by a gusset, there’s a slightly shallower bend to the seat tube, the internal cable routing has been improved and the non-driveside chainstay is no longer elevated. It still gets a chunky tapered head tube, radically sloping top tube and Marin’s MultiTrac single-pivot suspension design, where the vertical shock is driven by a rocker link. Shock length and stroke remains the same compared to the previous model (210x50mm), but Marin has teased out another 5mm travel to bring it up to 130mm. Although most, if not all, of this extra travel will be down to the chainstay lengths having been extended to 430mm across the size range. As the old Rift Zone was not lacking in length (at the front at least), Marin has not felt the need to comprehensively overhaul the sizing. Instead reach numbers grow by 5mm across all the sizes except the XL, which goes up 10mm. As head tubes have also been extended by 10-15mm, and the seat tube has been steepened by 1º, the seated riding position shouldn’t actually feel too different. But by stretching what was one of the shortest chainstays on the market, the new Rift Zone should feel more in proportion than it used to. The head angle remains a balanced 65.5º, at 337mm (measured), the BB height is thankfully not as tall as advertised, and Marin must be commended for keeping the seat tubes stubby and the standover generous. Which means the profile of the Rift Zone not only resembles an old four-cross bike, but it can be thrashed around like one as well. Consumers get to choose between …Continue reading »

Highs
  • Exploitable handling, whatever your level. A bike that can grow with your skills. Fun to ride. No gimmicks.

Lows

Highs
  • Fun and unusual synthesis of parts and geo

  • Great build kit

  • Adaptable frame platform

Lows
  • Mix of progressive and dated geometry

  • Heavy and sticky for a short travel bike

This short-travel shredder takes a modern trend and brings it to the entry level. The Marin Rift Zone 2 does (almost) everything.

Highs
  • Unbeatable value

  • Smart spec

  • Forgiving but familiar geometry

  • Supportive suspension

  • Oddly shaped brake levers

  • Shimano chain and crank would have been nice
