Yeah, it won't be an issue for me. However, I had noticed that, and measured just out of curiousity. I'm actually 2.5-3cm behind the center of the BB. That last side-view picture is a bit deceiving too, the fence line makes it look almost inline, but the front wheel is slightly downhill. If it did become an issue for some event, I could slide the saddle back a couple cm and sit a little further out on the nose. The no-slip on the nose of the Prologo is nice for that, I didn't feel myself shifting around at all.
I did get out on the road for a short time yesterday. I've got a nice, slightly rolling road where I can put some real miles in. I noticed a few things. First, I rolled over some reflectors in the road and almost immediately ejected the water bottle. I'd really like some opinions from anyone with similar experiences (or disimilar, maybe mine is defective, twisted out of the mold or something), or on an aero bottle/cage that actually holds in place.
Second, the disc was surprisingly hard to control. I've never ridden anything deeper than the 404s, but never had any issue at all with them in some pretty strong crosswinds, but man, I really felt like I was fighting it yesterday. It seemed like once I got up around 27-28mph I got a strong gyroscopic effect; I was trying to counter-steer for the crosswind and it didn't want to let me
Now, this road runs north-south with winds out of the west, so I expected the crosswind, but didn't think it would be that difficult to control (and the wind wasn't that bad yesterday either). I'm 5'10" 155lbs so not heavy, but not terribly light either. I kept thinking maybe the cover wasn't screwed on tightly and it was gapping open at some point, but I checked and all the fittings were tight. Only other thing was I didn't cover the slot for the valve stem, myabe that didn't help? In any case, I'll take it back out this afternoon and give it another run, maybe I just need to get used to it.
Everything else felt great, it's going to be a lot of fun to ride. I'll do some short TT intervals today, I didn't really push anything difficult for too long yesterday, losing light too fast
