Team effort for team jersey
After a concerted team effort involving students, adults and our volunteer designer Jennie Hermann, we have a design for the Gear Grinders' jersey. Thanks to everyone who made suggestions and pitched in to create a truly great jersey in a very tight time frame. These long-sleeved jerseys will not only look good for casual and recreational rides but will dazzle when the high school team takes part in upcoming races. A number of adults will be donning them, too. If there is sufficient demand, we can place a repeat order in the spring - delivery takes 8-10 weeks typically.
