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.

Cheap Tricks: Trickstuff Brakes Are Too Expensive, So We Tested Their Brake Pads

Known for their outstanding power and beautiful finish, Trickstuff brakes are masterpieces. They’re also pricy and hard to find, especially in North America. But it’s not just about what’s on the outside that counts. The pad material Trickstuff developed is also pretty special, and you can get their pads for nearly any brand of brake. So Travis Engel slid some Trickstuff Brake Pads into his Shimano SLX brakes, and started stopping.

Specialized Aethos Review: Shining a Light on Road Riding w/the Aethos Disc Road Bike

Road bikes. We don’t really talk about them so much over here at the Radavist – anymore. There was a time however where we’d post galleries from road adventures and still to this day, one of my favorite rides I did in California was on all pavement. Still, there have been a few defining reasons for the wane of the road bike’s popularity and it wasn’t until I accepted the offer to review the lightweight Aethos road bike that I began to mull over these reasons. A 16lb road bike is both terrifying (am I going to break this thing?!) and a joy (WOW! this is incredible) to ride but what does the state of road cycling look for me, personally, and how did this review shape my perspective of drop bars after a long hiatus from enjoying the pleasures of road riding? Read on to find out.

The Pursuit Cycles LeadOut AR Prototype and Hand “Painted”

The Pursuit Cycles LeadOut AR Prototype and Hand “Painted”

During the fabrication of a Pursuit Cycles, Carl Strong’s custom carbon brand, each of the six sections of the MUSA carbon frame come out of the mold and then are printed with some stats. This includes mold number, frame size, layup version, and a number of parts made from that mold, then finally weight is handwritten on. Eventually, when the frame is complete and getting prep for paint these notes are removed. As this bike was one of the firsts Lead Out ARs to be produced this idea hooked me, I loved the process and tracking, I wanted to play into that. Taking some inspiration from recent sneaker trends as well. I decided on a Helvetica style to the point design.

Spaghetti Western: A XCR Tommasini X Fire Disc Road Build

What do you call a stainless Italian disc road bike, built with Cinelli and Campagnolo, right here in Santa Fe? Spaghetti Western? Sure, why not?

Mellow Velo, purveyors of modern bikes, with a long history of building up classic Italian road racing machines, recently completed this build for a customer back on the East Coast. Adam, the owner of the bike, refinishes mouthpieces for saxophones, so as you can imagine, he has a particular penchant for procuring pristine pedal machines like this one. Luckily for him, David from Mellow Velo has a soft spot for modern Italian-made frames.

Nao’s Own Tomii Cycles Chubby Road

Yesterday we took a deep dive into the shop of Tomii Cycles. Typically, builders use their own bikes to experiment and explore ideas, concepts, and construction techniques they’ll later use on their client’s bikes. This reasoning is why I always gravitate towards a builder’s own bike when I’m visiting a shop.
