OK, for starters, my body is dragging around an extra 20lbs since my dog crash 3yrs ago during my century *sigh*, BUT, can we please still entertain my mind's wondering here that my new wheels might be part of the drag I'm feeling on my bike...

For those of you that have had aero to semi-aero wheels vs traditional rim depth clencher... do you think you can really feel the difference?

I finally switched my stock wheels on my Orbea from the semi-aero Reynold's Solitudes http://www.reynoldscycling.com/index...m&p_itm_pk=603, to some Easton's, EA90 SLX http://www.eastoncycling.com/en-us/ea90-slx-698.

And upgraded tires, from Victtoria Rubinos http://www.biketiresdirect.com/produ...bino-road-tire, to Schwalbe Ultremo http://www.biketiresdirect.com/produ...cher-road-tire.

I think I have them mechanically installed properly. The rims on the semi-aero Reynolds were definately narrower. And I had to do a brake adjustment to open things up enough to get the Eastons in without things rubbing.

At first I hated the Reynolds being semi-aero. I noticed more side wind resistance being out in the open MidWest farm fields. But now I'm thinking maybe that little bit of aero helped the overall speed?

The weight I'm carrying is on-going nagging issue related to getting myself medically healthy enough to really ride and train like I used to. But the wheels overall have me wondering now. Thanks for any insight!
