When we race indoors during the winter we used the "old" Trinity Bomb One Blue (Ultra Stiff) inserts in our Pink Taper Pin slicks.
Trinity has now come out with an insert that is hard as concrete and requires massive amounts of time to dremel and shape the insert.
I was hoping JConcepts would come out with a Foam that was the equivalent of the "old" Trinity Bomb One Blue before Trinity changed the foams. Thank you!!
