Training wheel etiquette

My normal wheels are 60/90 and I've logged thousands of miles on the road without giving it a second thought.  In fact, I'll put in a few short rides with my disc before a race to make sure that all is functioning properly.  I think that you are way overthinking this.

Don't worry about it, buy, install, train, race! I ride with some roadies time to time, one rides a 5k bike with $2.5k worth of deep Zipp's, never races or anything.  Another guy has some 60mm HED and so forth.  I have a pair of FLO 60/90 and they're going to become my training & racing wheels.  Was on an older pair of Felt 40mm TTR2 but its a PITA to keep adjusting the brakes due to rim width diff so the FLO's are going on permanently.

Deeper may be faster but you need to know the conditions you may experience.  Will you ever see 10*, 15*, 20* yaw angles?  Even if you do it's probably not all that much, so the faster front wheel may be the one optimized for 0*-10* and again that depends on the tire used with the wheel.  Have you seen FLO's new wheel data and other aero info?  Good stuff, and if one believes the data they have, their fastest wheel in most prevalent conditions (0-10*) with their recommended tire would probably be the 60 front.

Those who know what you are running are just as likely to think you have them out for a test or check out ride before a race if they even give it a second thought.  Those who have no idea what carbon wheels are will just think your bike looks pretty cool.

Bottom line the only thing most people will probably be thinking is "why do these people insist on being out in public wearing spandex."

I don't ride with my race wheels in training for the following reasons...

1.  I can't afford to be replacing race wheels if I trash them in training.
2.  I train a lot...and I have broken many spokes, cracked a few hubs, and bent a few brake tracks just in the last 5 years.  I have completely trashed 4 training wheels.
3.  I run fast tires and latex tubes on my race wheels.  I prefer not to swap them out each time I go between training and racing.
4.  I use a different cassette for training than I do racing...so another thing I prefer not to always have to swap.
5.  I bought race wheels with the intention of going fast during races.  I have no desire to use them in training unless I know I'm going to be riding with guys who are much faster than me and I need all the help I can get just to keep up.
