I've temporarily sidelined the 44mm Rene Herse Manastash Ridge Extralights with Schwalbe SV-17 tubes on the Seven in favor of a pair of 44mm Rene Herse Snoqualmie Pass Extralights with Rene Herse
TPU tubes. This is the beginning of an experiment (probably at least a year) with the TPU (thermoplastic polyurethane) tubes. The Snoqualmie Pass tires are a known quantity, well-designed all-road tires with 2225 miles logged on the LHT. The TPU tubes are a novelty, with an intriguing technical story. I intend to ride them hard over the coming season. I got started with that this afternoon, making a quick run up the Minuteman to Lexington Center and back on the Seven. My initial impression was of swift comfort. We'll see what the verdict is in a thousand miles or so.
Meanwhile, the Mile 4.0 Cairn Builders are back to miniatures, and lots of them. I could get used to that. Story time!
