Our Standard bobbin is probably the most popular of all the models we sell. More than likely, that&';s because it&';s the model that works for just about any fly pattern you may want to tie. From small midges up through bigger saltwater flies, the Standard does it all. With a premium-quality ceramic tube, it&';s also going to be very durable. And of course, it wouldn&';t be a Rite Bobbin without the one-of-a-kind brass tension adjuster, allowing you to have more control as you tie. This is a must have for any serious tier.
