According to Alex the owner of RSD, the Sergeant can be run 27.5 plus, 29er, or 29+. If set up as 29+, the bottom bracket height rises by 10mm. This is fine by me, as I'm sick and tired of pedal strikes where I do the majority of my riding here in Bellingham.I wasn't aware the Sergeant could accommodate 29+. Is that only for ti-frame models? or applicable to the standard aluminium? If common to the aluminium, I will go buy the Sergeant. I was torn between this and something like the Stache 7 which takes both sizes.
Here is the pic sent to me by Alex of a Sergeant set up as 29+. I posted it earlier but here it is again. There's no difference between the specs for the Ti and Alum...just a drop in weight and of course some nice Ti-'give' to the back end.
Others might be bothered by this setup thinking it might be too short a wheelbase, or the xtra 10mm rise in bb height, but my style of riding is mostly super fast going uphil, and moderate on the downs. My jumping and freeride days are over...lost interest, and also have a former back injury that only flairs up if I start riding too aggressive on the downs... I'm more into all day rides in the saddle, lots of climbs, lots single track, mid size jumps are ok, but no more big stuff.
...So for me the 29+ Sergeant will be perfect. Alex talked me out of the Big Chief 29+ and pushed me toward a Sergeant with 29+ setup...as I'm 5'8" and the Sergeant will end up being more manouverable for me.
