The SD Expert stem is a budget friendly option perfect to run as your race stem when you're moving up into the 1-1/8th steerer tube size. Combine it with a SD Expert bar to freshen up your cockpit without breaking the bank. Available in two sizes, the 40mm option is one of the shortest 1-1/8th stems out on the market. Great for when you're moving up a frame size and want to keep things tight.
