I see TS26 fits to Dot, sport 2015, phil&teds nav. Will it also fit my red classic, sport, dash, explorer, hammerhead or black classic?

TS26 will not fit on a red classic, sport (pre 2015), dash etc is because of the metal hinge plate; this prevents the travel system from sliding in far enough for the nib springs to engage.

TS26 will fit but has not been safety tested for explorer, black classic, or hammerhead. We should not be recommending use of it with these models.
