YES. To encourage a good pairing with our wider drop bar we recommend sizing down. There is no exact rule that will tell you which size is best and in the end the decision will come down to personal preference. However, a basic guideline is for every 20mm wider your bar is, your stem should be 10mm shorter. For example, if you're currently riding a 42cm bar and your stem is 110mm, the 80mm Coast Stem would be our recommendation if you select the 48cm Coast Drop Bar.
