Mine were buggin me a little on my Strada. I realized I was about a 1/4 inch off on my seat adjustment then it was all better. Hard to believe a 1/4 inch over extended would do that but it did.

You know thinking about it now, I did just set it up like a road bike not figuring in the cleat postion for my SPD's. I never thought about the fact that the cleat is more in the middle of the shoe VS the toe. Also I think the angle of the seat if you go to far throws your knee position out of whack i. Although I never had a problem before and I have been riding recumbents for sheeezz since 1989 or so. Hmmm LOL
 
Oh yeah it probably did not help that I had two variations of SPD's and the ones on the bike were different then my Shimano cleats. Sooo zero float I am sure did not help either. I really hate that there are like 5 different types of SPD's. You would think I would have checked after I had the same issue with a spin bike not long ago. Some how I always rationlize it out as a stiff pedal or something.

I put that same crankset on Terrie's SXP when we got it -- figuring that the 165 with lower gearing would help a bit instead of the 175, since she's anything but a power rider, and is 5'5" vs my 6'1"...
 
I used to be able to hit 35-36 mph on the proto Xstream during the "final sprint" section of the GDB Mesquite ride, but top out at 21-32 on my current bike...  I think it's a combination of 559 (now) vs 650 (then) wheels, slightly less aero position (seatpad foam addition raised me up a bit vs. the pedals), and also being in not-quite-the-same shape as back then.
 
Hope you never have to use the 22/34 combo, Jay -- you may be able to spin, but the steering at that low speed will become quite the challenge! Dan Schaaf (Squarecorners) told me that John Schlitter suggested to him to drop one hand off the bars and steer with one hand when doing <5-6 mph climbing - it will reduce the steering wobble at really low speeds  -- and it works!

You're using PLATFORMS on the Xstream???

The bike has the custom cassette that Terry P. installed, when he owned it. The largest cog is 30T. Just to make it easy on my knees, I've used the 22/30 combination riding up the WR Trail detour paths either side of NW Hwy, and experienced no excessive wheel flop. I'm remembering a super-steep hill at Lancaster that almost ate my lunch. At the bottom I shifted to a 30/30 combination (Smallest chain ring was 30T), and before I reached the top was having thoughts of getting off and walking. I think I could easily take it with the 22/30 combination. I'll have to try that one-hand, low-speed steering method.
