im less curious about the sora junk and more so in the soft tail. it looks like an engineers worst nightmare, but 25 year warranty pretty much takes care of that and for $650 retail, asumming they're being honest about the weight, it doesn't look half bad...

When you say "an engineer's worst nightmare" I assume you are concerned about the flexing forces on the chainstays leading to breakage. Well think about a normal coil spring - nothing but a rod of steel, wound into a spiral, flexing up and down ad infinitum. You just need to choose the right steel. You dont make a softtail out of Reynolds 853.

My girlfriend has a KHS softtail MTB and loves it. I've ridden behind her and watched the softtail in action (no jokes here please!) and it absorbs bumps well without creating any noticeable bobbing due to pedalling forces. It's not a full suspension bike, it just takes the harshness out of big hits and absorbs "trail buzz" completely. She used to own an aluminium hardtail MTB with a suspension seatpost and she says she would never go back.

My only concern is with the elastomer bumper in the shock. It seems to be rated for a light to medium weight rider. No optional aftermarket bumpers seem to be available. I've seen heavier softtail riders blow through what little travel they have by just sitting on the bike. So if you're a heavyweight you might need to do a little research.

But dont be concerned about steel being able to flex, otherwise the suspension springs in 95% of the world's cars would be collapsing underneath us.

I second OffRoadTourer's comments about absorbing the buzz while smoothing, but not eliminating, big hits. I've had the '01 Team model Cyclocross ST (TrueTemper OX vs. the Reynolds of the CX100) for about a year; my take on it is that it's like generously increasing the vertical compliance of a good steel frame like a VooDoo Wazoo. I'm up in the Clydesdale range and I was worried about the lack of heavy-duty bumpers for the shock, but it still works well for me. One trick, passed on to me by a guy from KHS, is to place a nickel in the shock tube, beneath the elastomer, to give a bit of "pre-load". Haven't tried it myself, but he swore a lot of people were doing it.

One thing to watch out for, if you do go for the CX100, is to be careful about the sizing. I got a medium frame, based on their published geometry, but found that some of the measurements must have been outside-to-outside, rather than center-to-center, as virtually everyone else does it. This means I wound up with a significantly shorter top tube than I expected, but it's been OK.

If you don't mind what is the standover on your medium?
I've been thinking about the Team ST that is on Ebay, but it's a large.
Trying to get an idea how the sizing runs.
