I’m looking at the Maxxis price list and the DHR II 29 x 2.4 WT DD is only available in Maxx Grip, not Maxx Terra.
However they do offer the 29 x 2.3 DD in Maxx Terra if that helps? Product code TB85927400
New Assegai and Dissector DDs are all Maxx Grip too.
The Aggressor comes in a 29 x 2.50 WT DD with dual compound or the High Roller II 29 x 2.50 WT DD is available in Maxx Terra.
Hope this helps.
