2025 Sea Otter Finds – Day 1

By Sheri Rosenbaum
It was great to see so much excitement within the cycling industry at this year’s Sea Otter Classic, There were so many brands launching new helmets with the focus on safety, cooling, and aerodynamics. Sustainability was also a focus, with brands not only talking the talk, but walking the walk. I lost count of the number of brands launching ePumps, hopefully making CO2 cartridges a thing of the past. Read more.
Randonneuring Rookie: Tales From the Long Road

By Sheri Rosenbaum
With origins in late 19th century France, Randonneuring grew out of interest in touring the countryside by bicycle. It is a long-distance cycling sport where riders attempt courses of 100K with options of 200K+, passing through predetermined “controls” (checkpoints). Riders aim to complete the course within specified time limits and receive equal recognition regardless of their finishing order. Riders may travel in groups or alone and are expected to be self-sufficient between controls. Randonneuring events can be ridden on paved, gravel, or mixed surfaces. Randonneurs USA (RUSA), the national body that sanctions randonneuring in the US, introduced a new gravel program in 2022. Read more.

Does washing my rain jacket hurt its water-shedding ability?

QUESTION: I recently bought a rain jacket for cycling, which I also wear as a windbreaker, but it’s a bright neon yellow color and it’s already looking dirty. I haven’t wanted to wash it so as to keep it water repellent, but a fellow rider tells me that washing it won’t hurt its ability to shed rain. Can that be right? —Neil S.
RBR’S STAN PURDUM REPLIES: Your friend is right to a point. It is important to wash your rain jacket periodically because sweat and oil from your skin deteriorates the breathable waterproof membrane and dirt can clog zippers and cause them to wear out. However, over several washings the Durable Water Repellent (DWR) finish on the outside of the garment diminishes. Fortunately, the DWR finish can be restored by means of a spray. Read more.
