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

Sour Bike Ready to Ship (and On Sale!) Frames

Sour Bike is on a roll this year with a lot coming up next year! To close the year out, the brand has a small rolling stock of frames at its facilities in Dresden that are ready to ship. Sour builds everything in-house, so sometimes there’s a wait time for us to weld and powder coat everything, but these frames are done, powder coated, and ready to go out the front door and under yer butt for 2024!

All the frames carry the same warranty as usual, and are mostly colors we wanted to test out, or frames used to fill out a painting schedule.

Sour can ship these globally as a frame or frameset, or your local dealer can build these up to a complete frame, including Sour’s dealer/distributor in Bend, Oregon, Chariot Bikes.

Check out the full inventory at Sour Bikes.

Rolf Prima Debutes Vigor FX and Polished Vigor Rim Brake Wheels

Rolf Prima just rolled out a limited edition run of polished silver Vigor and Vigor FX road Wheelsets. The Vigor is RP’s long-standing best-selling wheelset. With a thirty millimeter depth, paired-spoke design and fast-spinning USA made hubset made by White Industries, it rivals the weight and speed of many carbon offerings at a fraction of the cost. The polished aesthetic adds a classic touch to a cult-classic.

The FX, the single-speed/fixed version offers the same unique profile and ride quality in a simple-yet- classy one-gear variety. This limited run was inspired in collaboration with their long-time Japanese distributor, now available state-side while they last.

Get yours at www.RolfPrima.com. Both versions are rim-brake only. The Polished Vigor sells for $1,199.00 and the FX for $1,099.
