The large box behind the saddle contains the crankset. I chose the 172.5 crank arm length with the more or less standard 53-39 chain rings. I chose the double front because I very early on determined that the hills in and around the area where I live can all be conquered with the gearing available with these chain rings. I can climb anything I come to around here in a 39x26 and actually I do almost all of my climbing in the 39x23.
Next is the rear derailleur, the mechanism for moving the chain to change the gears on the rear wheel. Next is the cassette or sprockets for the rear wheel. The cassette choice is the 13-26. This features 13, 14, 15, 16, 17, 18, 19, 21, 23 and 26 toothed cogs. I ride mostly in the 17, out in the middle of the cassette. I don't sprint much but when I do I usually get only to the 15 or very occasionally the 14. As I said above, I climb in the 21 and 23 with the 26 for the likes of the Myrtle Street hill.
Next over is the front derailleur, the mechanism for moving the chain between the rings on the crankset. The largish twin boxes hold the brake lever/shifter mechanisms and cables for connecting up all of the parts. The smallish box in front holds the bottom bracket.
A note on the saddle, I had been riding a fi'zi:k Plateau. The Selle Italia Flite is highly praised, generally considered to be one of the two or three top saddles available for this kind of riding. I wanted to try it out. I rode it a couple of hundred miles and just never really adapted to it. I found a new titanium rail Plateau on eBay for an excellent price and made the switch back to fi'zi:k. I have since also equipped my Michigan bicycle with the same saddle, albeit with the stainless steel saddle rails.
The bottom bracket tool is not a single use tool as it is also used to tighten down the cassette onto the rear wheel (same groove and spline pattern). You don't have to measure torque on this application, you just want it good and tight. I had messed with cassettes a few times previously and I already had the large box end wrench for this task.
Yesterday in Sedan FC Nantes and CS Sedan played 90 minutes of scoreless football and followed it up with 30 minutes of scoreless overtime football. The game was then settled by a penalty kick shootout. Sedan prevailed 4-2, eliminating FC Nantes from le Coupe de France. As noted by their manager after the result was final, FC Nantes is now free to concentrate on the item of overriding importance, the championship of Ligue 2 and return to Ligue 1.

Sort of fascinating, even to a mechanically challenged bicyclist. So you have the right tools and the experience to say, change out a bottom bracket, should it be necessary? What are the chances of stripping the threads during the process? Congratulations on the Record/Chorus choice. :-) Does the same logic apply to DuraAce and Ultegra on the Shimano side? SS
LOL. You guys are both bicycle geeks!
