Trek 4300 with disc brakes: Held up great despite being aluminum.
Michelin City Slicker tires: Amazing, only punctured twice, and never changed. Unfortuantely, I think they've been discontinued.
Brooks B-17 saddle: Great.
Blackburn rear rack: No problems.
front suspension-compatible rack: Can't remember brand. Only had to replace part that mounted it on fork.
2 Totonka Land Cruiser rear panniers: Attaching clips were plastic but held up well. Clip that attaches at bottom eventually was ripped out, but it's an easy sewing job to re-attach it.
2 Arkel front panniers: Only could be better if they were waterproof. Canadian brand, might be hard to find elsewhere.
OGC handlebar bag: Great mounting system. Zippers eventually failed.
Blackburn frame-mounted air pump: Great.
2 water bottles: I wouldn't recommend putting sweet drinks in your bottles, mine eventually got moldy.
Trek headlight: I sent this home after a few months, although it would have been usefull in dark tunnels.
Trek rear light: Great.
front and rear fenders (the cheap plastic kind): Highly recommended to keep you a bit dryer on wet days.

2 carabiners for attaching gear: Useful.
Finish Line cross-country lube: Good lube.
small shammy for wiping down bike: Useful.
Camping Gear:
North Face Slickrock 2-man, 3-season tent: Got a bit wet under long rains, but was great after I rigged up my ground sheet as an extra roof layer. I'd take it again.
North Face Superlight down sleeping bag: Very warm.
MEC silk sleeping bag liner: Recommended to keep your bag clean and for hot nights.
Ultralight 3/4 Therm-A-Rest: Great, was all the padding I needed.
MSR Whisperlite International camp stove: Wroked great at all altitudes, just needed to be cleaned a couple of times.
pot and pan: Another smaller pot would have been more useful than the pan.
Outbound Aurora candle lantern: I eventually sent this home and just used my headlamp. Unneeded extra weight.
2 butane lighters: A must.
Swiss army knife: Infintely useful. Scissors come in very handy.
camp soap: Great.
small shammy: Great, all you need is a very small one. Highly recommended.
Nalgene 4-litre water bag: Kept getting holes in it. I threw it out and started using simple plastic pop bottles.
Platypus 2-litre water bag: Ditto above.
Petzyl Tikka headlamp: Amazing, lasts forever.
Katadyn Mini water filter: Good filter, but I only used it twice. Doing the same route another time I'd only take water purifying drops.

MEC Sentinel Gore-Tex pants: Great.
MEC cycling rain jacket: Great.
light fleece sweater: Great, I wore this everywhere.
North Face long-sleeved base layer: Great.
zip-off hiking pants: Good for hiking, superfluous for anything else when you have the gore tex pants as well.

reflective leg band for cycling with pants: Unnecessary if you're riding in tights.
Smith sunglasses: Great.
Trek Fast Eddy cycling gloves: Great.

Repair Gear:
bike tube patch kit: A must.
Park Tools multi-tool: Get the one in the neoprene pouch rather than the one built into a plastic case.
3 cone wrenches: One doubles as pedal wrench. Occasionally useful and very lightweight.
Phillips screwdriver: Useful, but try to get a Swiss Army knife that has one already.
spare nuts & bolts: Never used, but you never know.
tent repair kit: Ditto above.
Blobb Ding-All wetsuit and board repair: Useful for repairing water bags, but my advice is leave them all at home and use pop bottles.

first aid kit: Again, don't leave home without it.
sewing kit: Very useful.

mini tripod: Very useful for solo riders.
solar-powered battery charger: Useful, I attached it to the tops of my panniers with heavy duty velcro.

mini cassette recorder with cassette: Never used.
money belt: I wore it while riding, just in case.
Travel International maps: Great.

Lonely Planet South America: Useful, but it's up to you whether it's worth its weight.
mini Spanish-English dictionary: Geat.
journal: A staple.
Moleskine notebook: Invaluable.
2 pens: Because they tend to run out of ink at the least opportune times.
travel toothbrush, toothpaste and floss: Becasue no one wants stinky breath.
contact lenses & solution: Solution is hard to find and expensive in Bolivia.
sunscreen: A must.
insect repellent: Wasn't used as often as I would have thought, but useful nonetheless.
