World Championship level performance does not come easy, JConcepts developed the Blockers tire for the highest level of competition. During the IFMAR Worlds in Perth, Australia, JConcepts had a handy option ready for main event track conditions. The Blocker, a relative of the popular tires, Stalkers and Reflex, have an even tighter tread pattern for long main events or very abrasive conditions.
The design team checked over the carcass dimensions, profile, overall height and width to assure the best balance of weight and drivability. The Blockers began with a Stalkers style pin which has slight angle on each side for separation at the top. This fine detail gives increased bite in wet conditions providing some versatility to the design. As the pins meet the base of the tire, the spacing tightens considerably giving a stable footing for the Blockers.
A lot of technique is used in designing tires, however, the Blockers simply use more pins. The technique and experience comes into play when deciding where and how many. The JConcepts professionals analyzed the latest race worn tires and simply knew what to do. Using softer compounds such as blue and green, the tire has incredible stability and flexibility for fast qualifying. The additional pin real-estate provides a lot of cushion for extended main events and when paired with long-wear compounds such as R2 and O2 the race pace can be pushed out to 45-60 minutes with ease. The stacked row configuration and simple connected pins offer massive forward acceleration.
The aligned rows allow some surface drift making the tires forgiving in sand and bumpy track sections. The outside pin has been clipped to help drive-ability and ease the initial turn-in drivers often have concern for. The JConcepts tires include the Dirt-Tech closed cell inserts made famous by their gray color and durability. The package is complete with re-sealable, zip-top packaging and backed with JConcepts customer support and racing heritage.
At the races –
The Blockers, in the hands of Ryan Maifield, took the Pole Position at the 2018 IFMAR World Championships in Perth, Australia. In a last minute move, the top JConcepts pilot “went for it” and prepped and mounted Blockers for the all-important Semi-Final event. Ryan simply outperformed the competition taking the quickest time of the event and placing himself out front for the 60 minute A-Final event.
