Chumba Slackr Hardtail Review: Re-Centering Hardtail Geometry

John took a Chumba Slackr hardtail home from the 2024 MADE Bike Show to review. Since then, he’s squeezed every bit of riding potential on the bike before winter set in early in Santa Fe, putting it and himself through a multitude of rides in the Southern Rockies. Find out what epiphanies he’s had while riding this Austin, Texas-welded titanium hardtail below…

Trek Teases Steel Full Suspension PipeDream

Trek Teases Steel Full Suspension PipeDream

Trek just teased this steel (and carbon) full suspension “PipeDream” prototype on its Instagram, designed by Trek employee and industrial designer Kyle Neuser and built in-house by Trek’s prototype lab. Inspired no doubt by the work and growing popularity of steel full suspension bikes from the likes of REEB, Cotic, Starling, Chromag, and more, Kyle was lured to experiment with the natural damping of steel with the geometry of the Trek Top Fuel.

This steel frame uses a carbon swingarm from a Top Fuel and rocker link, exposed cable routing, and bolt-on aluminum shock mounts. The PipeDream is finished with a paint scheme inspired by Trek’s steel bikes from the ‘80s and ‘90s. If Trek were to pony up and make a production run of these bikes, would it ignite a race for more metal full-suspension bikes? Hey, Specialized, you won’t! Let’s see it!

2024 Rocky Mountain Instinct Review: A Cosmic Trigger

John likes to review a carbon full-suspension bike at least once a year to challenge his opinions on his preference of chassis material, and this summer’s bike is the 2024 Rocky Mountain Instinct. Thanks to new geometry, details, and a simplified RIDE-4 adjustment, the Instinct proved to be a very capable 140/150 trail bike. Perhaps the bigger picture of this review is John’s ever-questioning of his quasi-religious, cult-like zealotry for metal bikes…

Artificial Selection: A Revel Bikes Tirade 29er Hardtail Review

Announced today, the Revel Bikes Tirade is a 29er, 140-millimeter travel titanium hardtail, unlike anything the brand has offered in the past. With generous tire clearance, beautiful cable routing, and more, it’s clear Revel has used merged its own design prowess, learned through making phenomenal full-suspension bikes, and the re-labeling of its titanium brand, Why Cycles, to force an evolution of the almighty hardtail. Read on for John’s nerdy science talk intertwined with commentary on how hardtails are still having a moment in 2024 below!

First Ride Review: Introducing the Updated 2024 Pivot Switchblade

The Switchblade has been one of the best-selling bikes in Arizona-based Pivot Cycles‘ lineup since the first version dropped nearly eight years ago. Utilizing a DW-Link platform, it was one of the first full-suspension bikes to incorporate Super Boost rear spacing with either 27.5+ or 29″ wheels. Its last major overhaul was back in 2020 – which saw the bike grow bigger, longer, and lighter – and today Pivot introduces the next iteration of the Switchblade with geometry and kinematic advancements they claim “sets a new bar for how a 140-150 mm travel Trail/Enduro bike should ride.” This launch also celebrates the 35th anniversary of the first bike built by Pivot’s founder/CEO Chris Cocalis back in 1989: the Sun Eagle Talon.

Josh Weinberg, who lives just up the road from Pivot HQ in Phoenix, AZ, recently spent a couple of days getting to know the new Switchblade on some of his favorite trails and, below, shares a first look at the new model and some initial ride impressions…

Speed Metal: A REEB Steezl Review

There was a very broad range of very specific questions rattling around in Travis Engel’s head as he waited for the REEB Steezl to arrive. A lot more questions than normal. Usually, all he has to do for a bike review is keep riding it until he can put all its variables into context. The REEB Steezl, on the other hand, was top-to-bottom known-unknowns. It’s a U.S.-made steel full-suspension mountain bike, compatible with multiple shocks, multiple chainstay lengths, and made of multiple frame materials. Things got interesting. Hold my REEB.

Josh’s Favorite Products of 2023

It’s been a wild year around these parts. In addition to the organizational changes we experienced with this website, I feel fortunate to have met and collaborated with many amazing people in addition to traveling to some truly remarkable places. My list of favorite products ended up being rather eclectic, but I think it reflects the wide range of material we get to cover here. Of course, music was an integral backdrop to my work – on rides, traveling abroad, and with my family at home – so I have joined some of our other contributors in offering a selection of favorite tunes, alongside a handful of products, below.

Episode IV: A New Hope Tech 4 V4 Hydraulic Disc Brake Review

Earlier this year, UK-based Hope Technology released an updated version of their popular four-piston hydraulic brakes, the Tech 4 V4. The 2023 version is equipped with the same robust CNC-machined aluminum, easy adjustability, and stopping precision that contributed to the success of previous models. But where the Tech 4 V4 seeks to improve on the Tech 3 V4 generation is in its all-new lever design and revised caliper that promises increased power and improved ergonomics.

While it’s no secret we’re big fans of mechanical brakes here at The Radavist, we can also appreciate the confidence-inspiring feel of a solid four-piston hydraulic brake, particularly on full-suspension bikes. Josh Weinberg had years of experience using the preceding Tech 3 V4 on his 150 mm travel Oddity hardtail so, naturally, he wanted to see how the updated version performed over a long-term testing period aboard his Starling Murmur.

A Multi-Bike Review of the Tumbleweed Big Dipper Drop Bars

A Multi-Bike Review of the Tumbleweed Big Dipper Drop Bars

Wide bars are becoming more and more prolific in the drop-bar MTB, touring bike, and even gravel bike subgenres. A craze that began with the Crust and Ron’s Bikes Towel Rack bars has now become widespread in the industry, with multiple brands putting their spin on an ultra-wide offering. Among these is Tumbleweed, who have worked to design a model suited for the Stargazer touring bike (one of my favorites in that subcategory of drop-bar bikes). Fittingly dubbed the Big Dipper Bars ($115), I’ve been stealthily test-riding them on two recent review bikes. I have some thoughts on the Big Dippers and the appropriate application for wide drop handlebars in general. Let’s check it out below!

The Dust-Up: We Need A Better Way to Measure MTB Seat-Tube Angle

Today’s edition of The Dust-Up is a nerdy little tour through the world of effective seat-tube angles. Travis Engel thinks that the way we measure them is a little … obtuse. That number on your bike’s geometry chart may not mean what you think it means. He informs his opinions by talking to some mountain bike brands who are taking a fresh look at this deceptively complex dimension.
