OK, before I start turning any screws I figured I'd ask ...don't wanna screw up anything! [rim shot]

I'm still very much transitioning from a comfort bike to my Tricross, so I don't want to be hasty and adjust based on anything that will correct itself as I acclimate. In fact, due to one reason or another I've put only 76 miles on the bike since I got it last month.

However, a few things I've noticed, which were repeated on my 28 mile ride today...

• I tend to migrate forward on the saddle as I ride. I don't slide off at all, but I have to consciously get my sit bones back where they belong every so often (an inch or two, maybe ?).
• When I'm 'forward', I notice a little more relative weight on my hands, naturally. When I move back, the wieght balance between saddle and bars is much better, best I can tell.
• My elbows become somewhat sore after a while, but that may be because I'm not altering position often enough (although I find that a bit hard to believe).
• I've not experienced any hand/wrist numbness worth reporting.
• Best I can tell, my knees are pretty much over the pedal spindles, if you subscribe to that school of thought.
• My saddle is level and its height is good, based on both ball-of-the-foot and instep measurements.
• I can't really use the 'hands off the bars' test, yet. Although the Tricross is far from a twitchy race bike, it is certainly more responsive than my previous bike and I'm not quite 'there' yet. However, I don't feel like I'm falling forward if I briefly take my hands off.
• It has an 8-position (shimmed) Specialized stem. It's in the low position, but not quite as completely low as it will go.
• The saddle is about 1.5" above the bars.

Whew! That's a list!

Based on that, I'm wondering if I need to try just a tiny bit of nose-up on the saddle, or if the stem needs to be flipped. I'm hesitant to un-level the saddle, as from what I've seen this can often address symptoms instead of causes. However, the reason I mention it, is that the saddle (a stock Specialized model that eventually may or may not be replaced) has a bit of upslope on the rear under under my sit bones. I wonder if that's contributing to my forward motion.

I realize I need to build core strength (not to mention, toughen up my posterior!!), fully acclimate and all that stuff, but feedback on cause and effect would be welcome.

Thanks!
