Presently I’m running the following on 29er stans flow internal 29mm.
‘Dry’ season – 2.5 DHF front, 2.4 dissector rear on 29er
Wet season – 2.5 Shorty front, 2.4 dissector rear.
The dissector seems to be a rare tyre that manages to roll fast enough in the dry and grip well enough in the wet. For me at least. YMMV.
The dry season one is buggered in a single season though, and thats -maxx terra.
Im about to try newest generation Magic Mary and Nobby Nic to see if the rubber compounds and carcasses are up to their promises of improved durability.
The DHR2 2.3 was as quick as the Dissector, possibly gripped slightly better in the corners, but lacked the cush of the extra volume in the chunder and suffered accordingly. More pressure to protect against pinch flats stole some of its grip and made it more uncomfortable. It did get even faster though.
