The Radavist

If you own a car, you change your oil. And not just because it’s part of adulting. Even if you know nothing about engines, you probably know what can happen if you push it too far. Debris will eventually build up, viscosity will eventually break down, and the more miles your car travels in that condition, the fewer miles it will last. But if you own bicycle suspension, the specific reasons for performing regular service may not be quite so clear.

Travis Engel knows a lot more about shocks and forks than he does about rods and pistons, but he doesn’t know exactly what happens when he blows past the manufacturer-recommended 50- and 200-hour service intervals. And like many riders, he pretty much always blows past them. So, he did some research and is here to tell us what we are (and aren’t) risking when we ignore the proverbial sticker in the upper left corner of our suspension’s proverbial windshield.

This is normally something we’d include in our Radar Roundup but it’s too good of a deal to wait until tomorrow. Kona is currently offering an N+1 sale. Buy any Process bike and get one free. This is a wild deal and indicative of what the cycling industry is dealing with right now but there’s no reason you shouldn’t be taking advantage of these offerings. Especially from a brand like Kona.

Roll on over to Kona to take advantage of these wild times.

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.

“Sky Island” is the twelfth layout of the Radavist 2023 Calendar. It was shot with a Canon R5 and a Canon f2.8 24-70, on Mount Lemmon, AZ. Photographed by Josh Weinberg.

“The sky islands of southern Arizona provide such unique terrain. During The Radavist’s editorial team week, Josh, Travis, Spencer, and John have been hustling to produce photos for our Reportage pieces. Here’s a sampling of what’s to come.”

When Brooks England decided to resurrect the legendary B72 saddle ($190), the brand reached out to John to use his 1980 Ritchey as a model to showcase the saddle’s history of being mounted to some of the first mountain bikes. Then, to offer a modern comparison, they built up a stunning Stooge Cycles Speedbomb. The resulting builds are eerily similar in some ways and worlds apart in others, yet the Brooks B72 looks right at home on both bikes. Let’s check out the new B72, including John’s quick review, below.

Normally, this review would get shuffled into a Radar Roundup. Let’s be real, it’s just a mountain bike grip. But Travis Engel has been using the new Race Face Chester for a few weeks now, and he thought it deserved a spotlight, thanks to its two available sizes and surprisingly clever design. Also, the next Radar Roundup isn’t until Monday, and the Chester launch will probably be old news by then. It’s just a mountain bike grip.

Prioritizing longevity and smooth shifting, Shimano’s LINKGLIDE technology offers an alternative to the weight and speed focus of most 12-speed drivetrains, with a new cassette designed to last 3x longer than their HYPERGLIDE+ technology. It uses an 11-speed chain, a new tooth design, and Shimano’s legacy HG freehub to achieve these feats. Whether it’s going on a new bike or bringing an old rig into the 1x world Shimano’s new LINKGLIDE technology might just be the right fit for you.

November 2nd is International SingleSpeed Day. It’s a celebration of Paul from Paul Component Engineering and his good friend Amanda‘s birthday.

The rules for celebration are simple: everyone, ride your singlespeeds! Gravel, road, or MTB; we’re all in on the one-gear birthday party celebration! John and Parker went out in Santa Fe for a sunset ride in the Dale Ball Trails, and they got some fun photos, so let’s check them out below…

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.
