Our Radar Roundup compiles products and videos from the ‘net in an easy-to-digest format. Read on below for today’s findings…

Ultradynamico Mars JFF 29×2.22″ $65

We love our Ultradynamico tires but always wanted the rubber barons to make a 29er tire for touring bikes or monster gravel bikes. After many late-night texts, our wants and desires were met this week with the announcement of the Mars JFF 29er tires. Check out the full scoop at Ultradyanmico.

e*thirteen Helix R and Helix R3 Direct Mount Rings $69.95 – 94.95

If you have SRAM or e*thirteen Helix, TRS, LG1 or XCX direct mount cranks then e*thirteen has a few options for you. The new Helix R or Helix R3 AL-7075-t6 aluminum chainrings will mount to all the above. These rings come in a highly CNC’D technical finish and will match e*thirteen cassettes perfectly. Check out the full drop at e*thirteen.

Curve’s Kevin of Steel Gravel Bike $6,799 – $8,299.00

Anytime someone does a Land Cruiser homage, you know John will catch it. Our friends at Curve Cycling just announced on Instagram its Kevin of Steel gravel bike is back for a limited time in limited quantities. Available in four build kits, five sizes, and a beautiful Desert Tan paintjob with a Curve Land Cruiser homage graphics package. See the full drop at Curve.

Bjorn Probka Cork Saddle $300

Bjorn is perhaps best known for its high end carbon saddles and so we were surprised to come across this cork saddle. Cork is resilient, moldable, and comfortable with excellent damping qualities. While the pricepoint is still high end, we can’t wait to see these saddles on some show bikes in the future! See more at Bjorn.

Frontier 300 2022

Another Coast to Coast? Yes, ……… and No. While the Frontier 300 does stretch from the Irish Sea to the North Sea, the challenge is more about what lies between those shorelines. The route doesn’t link together iconic roads or tourist honeypots, but journeys through the heart of the old Border Marches, to reach the Salsa beach welcome – food, fire and frontier hospitality.
