Kogel Bearings: Shimano GRX 12-Speed Kolossos Oversized Derailleur Cage

Kogel Bearings brought low friction and precise shifting to GRX 12-speed gravel bikes with this Kolossos oversized derailleur cage ($474.99). This upgraded cage fits mechanical 12-speed (RX820 series) drivetrains for Shimano GRX 1X rear derailleurs and is designed to enhance chain retention and reduce friction while shifting, even under load.

The overall length of the Kolossos is within a few mm of your stock cage, so ground clearance is not a concern. It is also equipped with road seals for optimal efficiency, but can easily be switched to cross seals for wet riding conditions.

Sueños de Colombia: Scarab Cycles Paramo Ultra Gravel Bike Review

The Paramo Ultra from Colombian bicycle builders Scarab Cycles is arguably the brand’s most versatile offering. With clearance for thicc tires, sliding dropouts, and comfortable geometry, the Paramo Ultra is inspired by the unrelenting high-elevation Andean mountain terrain where Scarab is based to provide a capable ride experience in even the most demanding pursuits. And because every Scarab is built to order based on a rider’s size, discipline, and style, no two builds are ever the same.

Josh has ridden a Paramo Ultra for the past six months both in Colombia where it was made and on his local roads and trails around the Sonoran desert. Below, he shares his thoughts on the build as well on Scarab’s overall approach to fabricating custom bicycles in the mountains outside Medellín…

Damn Well Good Enough: A Review of the Shimano Deore XT LINKGLIDE

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.

It Takes Two: John’s 1985 Steve Potts Signature

Marin County was a bustling time for the early mountain bike scene from the late 70s and well into the 80s. Names like Tom Ritchey/Gary Fisher/Charlie Kelly at the MountainBikes store, and Joe Breeze, Charlie Cunningham, and Steve Potts psychically and physically shaping the future of the then-fledgling sport with their fire-road ripping designs, torches and tig welders.

We’ve reported on Cunningham and Potts’ involvement in Wilderness Trail Bikes (known widely as WTB) over the past few years along with Mark Slate. In 1983, Cunningham, Potts, and Mark Slate founded WTB, and the trio began developing components in Marin, leaning on both builder’s fondness for innovation and exquisitely unique craft. While Steve loved to shape tubes with brass fillets, focusing on the form regardless of weight, Charlie would tig aluminum and shave grams anywhere he could. The two made for a dynamic duo of constructeurs.

By the time 1985 rolled around, mountain bikes were a legitimate tour de force within the bike industry. Even though they gravitated towards completely different frame materials and processes, Cunningham and Potts were credited with crafting some of the most iconic bikes of the era and still found the time to collaborate and share ideas.

As with many of the influential characters and pivotal moments in the early days of the almighty mountain bike, collaboration was key, and sometimes, it took two talented individuals to make a single bike…

1990 Klein Attitude Team USA

The mountain bikes of the late 1980s were not prepared for what the 1990s would bring to the American framebuilding scene, which was on the precipice of the aluminum revolution. Aluminum bikes were lighter and featured oversized tubing diameters, making a buff canvas for some wild paint jobs. This 1990 Klein Attitude is perhaps one of the most iconic bikes, donning the “Team USA” or “Dolomite” colors; green, white, and magenta—all sprayed on Klein’s thicc “Aluminum Power Tubing.”

While I was in Los Angeles, camping out at The Cub House, Sean got this bike all polished up for a quick shoot, so let’s check it out below!
