Regardless, that general design has been around for at least twenty years. It works. Sure, the pivot placements change, but the two that matter as far as wheel path goes are at the BB and DO. The big S has the arguably better DO pivot locked down. What are you gonna do, eh?

Having the linkages and shock low down and central are a good idea. It's probably a good ride assuming the geometry they used handles well and the shock rate is well thought out. Again, I'd try to find one and take it for a ride.
Pivots only count if they control wheel movement - shock mounts usually don't. And on the Sortie, the rear axle is mounted to a simple swing arm, or single pivot. The rest is just shock linkage, and doesn't affect wheel path. It's just a fancy "faux"-bar system.

Big-S got the "Horst" link nailed, it's a true 4 bar linkage - axle is on the seatstay part. I remember when Turner bikes had a license to build that system - then figured a "faux"-bar was almost identical, given all the control features built into rear shocks these days. Nowadays, they use the DW-Link, which uses a separate rear triangle attached to the main triangle with 2 short links. Most "2 short links" systems (Niner, Giant, VPP, DW) work well enough that you don't need lockout/platform settings unless you're out of the saddle stomping.

Right, that's what I said about the pivots controlling wheel path, isn't it? I suppose you are right, with this design it's only the one pivot at the BB controlling that.

Anyway, I'd only ever heard of a single pivot being referred to what Santa Cruz did for the longest time, which interestingly is the other style of suspension DB is using.

My wife got a Diamondback road bike recently. Was hard to find anything local that fit her! Anyway, it's entry level so nothing fancy but it seems nicely built. She likes it but she's not a particularly demanding customer.

that's the only size I have, I'll post pics if I ever get home long enough to go pick it up. And no it won't help the framing costs or the art conservationist who did work on it too

Looks great except you don't want to lay your bike down on the drive side. Lots of fiddly bits that could get bent and then you're really hosed. AMHIK

I'd rather place my bike gently on the drive side than mess up my brake disc.
I find my derailleur more forgiving and less irritating to deal with.

Of course it would be better to just keep riding until one reached their destination.

Which side has the more expensive bits on it?

...more expensive bits that can and will tear up chains, derailleurs, and dropouts. DAMHIK
