The Radavist

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.

After the bike industry woke up from its fever dream of futuristic mag wheels, Spinergy held on for one more go with their fiber-spoked SPOX lineup. Unfortunately, those first-generation SPOX would join the rest of those early carbon wheels to be remembered as educational, innovative, but ultimately failed experiments. But a lot has changed since then. Fiber technology has made huge leaps, and it’s now possible to weave a spoke that is stronger and lighter than steel. Berd spokes have been twisting our expectations for the past year, but Travis Engel was more curious about what Spinergy has learned in the past decades. Their MXX 30 mountain bike wheels, laced with their unique PBO spokes, make some bold claims. Travis spent a couple months on them to see if they delivered.

With so many options for handlebars these days, it’s difficult to stand out in a crowded market. With their new Loam Carbon Handlebar, PNW Components claims they have achieved the optimal combination of compliance, comfort, strength, and value. Available today, the Loam Handlebar is offered in either 38mm or 25mm rise, trimmable 800mm width, and 35mm clamp diameter. Josh and Andrea recently installed the Loam bars on her Ibis Ripmo and, below, offer an overview and first ride impressions…

⌀22.2mm or 7/8″ bars were all they had back during the genesis of the almighty MOUNTAINBIKE. Riders would take the entire cockpit off their dirtbikes and flat track racers: Magura L363.20 bars, Magura brake/clutch levers, and even Magura grips, mounting them to SR or Cinelli quill stems. A lot has changed since the late 1970s but one thing remains: people love these small-diameter clamp bars for their mountain cruisers, klunkers, hardtails, and rigid MTBs. You know, the bikes that get ridden super hard!

Paul Component Engineering offers their normal Boxcar stem in a ⌀22.2mm clamp, but today they announced a 6-bolt faceplate Boxcar Limited stem ($147.50 – $166.50).

John got his hands on one before the drop and has some photos and thoughts below…

Launching today, the LeMond All-Road Prolog E-Bike is the dropbar sibling of the original super-commuter/hybrid Prolog, which we reviewed last year. Equipped with Shimano GRX di2 and Mahle X35+ rear hub motor, the complete carbon build weighs in at under 30lbs. Richard Pool (aka Bicycle Crumbs) has been putting the Prolog AR through its paces in Portland, OR for the past few weeks and, below, provides a first look at the bike’s tech/design, and proposes which types of riders it’s best suited for…

Earlier this year I was able to spend some time on the Chris King GRD23 wheelset. It was during the tail end of Portland, Oregon’s rainy season and I rode the wheels, photographed them, and started typing, yet I kept thinking about the wheels and have revisited this “short and quick” review many times over. I was just trying to figure out what I was hung up on or why this particular review was so difficult. Even though I had almost nothing but good things to say. Sometimes it turns out that great products are simply hard to talk about.

The GRD23 is Chris King’s first foray into their own “house” wheels. Featuring a FusionFiber rim (we will get to that) with, you guessed it, a 23mm internal width paired to their legendary center lock R45D hubs. King’s design intent for these was for an all-road wheelset or a perfect wheelset for someone who wants to swap between their slightly-plump-road bike and their gravel bike.

Note: since I did the testing and took forever to wrap this up they have followed up with the deeper more road oriented ARD44.

Created by two climbers turned Physical Therapists, Wave Tools Therapy offers two portable soft tissue massage and myofascial release tools that lower the barrier to entry for routine bodywork. Hailey Moore has been using the original Wave Tool for years and, below, shares a brief review on why it and its successor, the Arete Scraper, should be essential for every cyclist.

In our current climate of cycling innovation, where maximizing gear range and number of cogs is top priority for many, singlespeeders are often left out. Teased earlier this year at Sea Otter Classic and available for sale today, Wheels Manufacturing flips the script with the SOLO-XD Single Speed Conversion Kit, which offers a reliable solution for converting both XD and XDR driver-equipped hubs to carrying a single gear. Josh recently received a SOLO-XD kit and, below, outlines the installation process and a review after riding with a “dinglespeed” setup for a couple of weeks.

Today, Shimano released the long-awaited mechanical 12-speed versions of their popular GRX gravel-focused drivetrain. With three 12-speed varieties to choose from (two 1x configurations and one 2x) and a list of desirable accouterments (optional dropper lever, interchangeable derailleur cages, refined wheelsets, updated ergonomics, and more), Shimano is covering a lot of ground in this new generation of gravel components. Josh recently had a chance to click through and pedal the wide range GRX RX820 groupset and, below, details the full product launch along with his first ride review…

Founded in 2013 by a group of mechanical engineers with a bad cycling habit (or, maybe the other way around?), Redshift Sports specializes in designing and manufacturing component systems to increase speed and comfort on the bike. In this review round-up, Hailey Moore assesses a handful of Redshift’s products—the Quick-Release Aerobars, Shocktop Pro Suspension Seatpost, Cruise Control Drop Bar Grips, and the Kitchen Sink Handlebar—and how they might benefit road and gravel-oriented riders as part of Redshift’s intended systems, or as standalone additions to any all-road setup.

Does it get much better than small makers addressing niche demands within a niche sector of the bike industry? I don’t think so. One of my favorite parts about running this website is showcasing and highlighting cottage industry bike businesses. Shovel Research is a small machine and fabrication shop that makes well-designed products that address a niche demand. One of which is its Rod Steward, a bag support designed for the Fab’s Chest by Ron’s Bikes, but as I found out on my Rivendell Bombadil, it works well with a Rivendell Sackville BagBoy bag.

Let’s check out a quick review below…

In the hunt for a better way to carry bear spray on his bike (or even carry it at all) Pat Valade found the Kermode Bearspray holder from Ghost Rider Equipment. An adaptable, light, and elegantly simple way to lash a can of bear spray to almost anywhere on your bike. And it’s designed and manufactured in British Columbia. Continue reading below for Pat’s thoughts following a few recent trips using the Kermode.
