By the way, I thought Claude's idea of changing all the fasteners on her bike to use similar tools was brilliant. You would think that bike manufacturers would have figured that out. This is especially true for bikes that cost $1,500 or more. I think when you are spending 15 times as much as a cheap bike from Walmart, you should expect 15 times the design considerations.
I also don't bring enough tools to anticipate repairing a bottom bracket, though I have had crank axles come loose on me twice which was maddening. Thankfully, it was an ashtabula crank and I could fix it with tools borrowed from a farmer along the way.
I tell, you, there is something to be said for those old bike designs that could be repaired 100% with a collection of average handyman's tools. Today's bikes are almost completely dependant on the special tools found at good bike shops.
Schwinn and Raleigh both tried that "our stuff only" hanky panky back in the 60's and '70's. By the '80's, they were both bought, sold, and dead only to be reborn in name only.
