The only concern I might have with Dissector’s and Rekon’s vs DHF or DHR II’s is traction.
I ride typical east coast trails (Connecticut). While there is some form of flow in some instances, the trails are predominantly slow rolling tech.
Most of the trails are undulating hills – constant up and down (100-200 yards either way) over the course of any particular trail and the climbs, more often than not, are as techie as the flats and downhill sections.
That being said, I am, like most riders in this area, trying to find the right balance between faster rolling tires and those that offer enough traction for the endless rock gardens and quick and constant sprint climbs.
You suggestions are well taken. A 2.6 front and 2.4 back seem like the best selection. When I do upgrade the bike (1×12 to replace the 2×10, new wheelset and new fork), I’ll absolutely upgrade the Rockshox Revelation to either a Rockshox Pike or Fox 34 (140) or Fox 36 (150).
