A road tubeless update: currently pretty frustrated with this technology. I love it in theory, but I can't rely on them to keep a good seal. Front tire developed a leak after being perfect for many months; rear tire was problematic for a while before that. I had put a tube in back, but the sudden problems with my front wheel on Saturday meant doing a fast descent in a race on maybe 30 PSI and then pushing that squishy tire up the big climb. I'd be interested in ideas or thoughts on tubeless. For now, though, back to tubes.
