Lighter wheels are faster. Shedding weight at the rim is really what matters though. Stan’s Alpha 340 road rims do a great job of this at <400g. Run them with tubeless road tires and you’ll feel the full effect. There has been some concern about their durability and road tubeless in general. Because these are a lightweight rim they aren’t for everyone. This means no Clydesdales. Using an appropriate nof spokes always helps life expectancy. Road tubeless is for real. The problem is, unlike mountain wheels, you need both a specific tubeless rim and tire. I’ve got these great lightweight rims in stock waiting to be built up for your order. Buying some speed is going to cost you a bit less too. $65 each while they last.
