Wondering how well you can fit a stock Gunnar? Use the handy form below to find out. Enter your saddle height (in millimeters). Then select your Gunnar model/size, select your stem and fill in the amount of headset spacers (in millimeters). When you press the Go button, it gives you a fit up sheet. If the Saddle Top to Bars and Saddle to Bar Drop matches your targets for these values, you’re in! Need help?
