Track Theorem Delta
The Track Theorem Delta attacks medium to heavy oil with an aggressive skid/flip motion. At its heart is the asymmetric MC² core, wrapped in the all-new Super Response Hybrid (HK22) coverstock — a hybrid that gets cleanly through the fronts, then flips hard off the friction for a sharp, angular breakpoint.
Tuned to a 500, 1000, 1500 Siaair / Factory Compound finish, the Theorem Delta stores energy down the lane and releases it with a strong, defined backend when it sees dry boards. Dressed in a striking Black / Indigo / Blue colorway and backed by Track's 2-year limited warranty, the Theorem Delta is an Upper Mid workhorse for bowlers who want length with a violent finish.
