Cal,
One thing I loved about working in a shop way back when, was that I had access to the exact spec parts I wanted. When I was racing, I had 5 serious bicycles, 2 of them were road bikes, the other 3 were cyclocross. The road bikes were: a Titan Epsilon SL (re-badged DeRosa) decked out with full Campy Record (Chorus crankset,) and a Vitus 979 with a Campy mix of Nuovo Record and Triomphe (Triomphe was the lightest full range gruppo that Campagnolo made and why my bike weighed less than 17lbs.)
The Cyclocross bikes were the John Waite 1x8 (handmade steel,) a Haro CX (rebadged KHS) with full Dura Ace, and a Felt Breed singlespeed. I used the Titan and the Haro for racing, everything else was for training and fun. The great thing about all these bikes is that since they were all 700c, I could (and did) build all my wheels to perfectly interchange with each other so I didn't have to adjust the brakes if I needed either a spare or just wanted to change tires by changing wheels. This was extremely convenient and it was as if I was my own support van. The last CX race I went to I showed up with 2 extra wheelsets in case I needed them or wanted a change of tires, or in case one of my teammates needed a wheel. It was my planning and access (as well as experience working with each of the rims) that enabled me to create a whole modular stable of 5 bikes that could interchange any of the wheels I had, with the exception of my Suntour track wheels. I'd say, even beyond gearing, having exactly matching brake profiles for all my wheels was one of the best long-term racing plans I made. I was planning on taking the Haro and the Felt singlespeed to the 2010 CX nationals out in Bend, Oregon until that car door dislocated my left shoulder on November 29, 2009. After that I was medically ordered to stay off the bike for a while (and physically unable to ride too.) I lost my job at the shop because they wouldn't put me up front in the retail/customer service part and I couldn't lift a bike into a stand and lock it in to be a mechanic. I was recently talking with Bethanne how that otherwise minor bike wreck changed my life and it's had a lot of downhill ever since. Only since 2017 when the VA helped me back into grad school, has it really begun to look up.
Anyway, if you can have all your wheels interchange with as many bikes as possible it is a game changer. I know you have 24", 26", and 700c wheels, so you can't easily interchange them all, of course.
