Hey guys- I was about to post a thread with almost the same question. I'm sure the OP will eventually have similar questions, so I don't feel like I'm thread-jacking too bad.
Most stock bolts are steel. Ti will be at least as strong as steel but 1/2 the weight. Aluminum will be much weaker (maybe 1/2-1/3 as strong), but also 1/3 the weight. That makes it suitable for low-load apps like bottle mounts and shift-lever clamps. Be aware though that Shimano levers usually require a smaller bolt head diameter. I couldn't find it at Toronto in aluminum, but they have it in Ti.
I've been pricing stuff out and found Toronto Cycles has an equal or better deal on just about everything but the rotor bolts. J&L on ebay seems to be the best deal for those...

My question though is this: How do I get the damn washers off of my old bolts? They seem stuck on there good. Should I bother ordering Ti washers, or will the local Ace Hardware have everything I need in steel for cheap?
2nd question: I have a 180mm front rotor. The bolts are exactly 1.5" long- 38.3 mm However, I can only find bolts in 35mm or 40mm. 35 mm might not be deep enough, and 40 would require a ton of washers. Ideas?
3rd question: for the steerer clamp bolts, mine seem to be M6x18mm, but the head is rounded, rather than tapered or non-tapered. They also stick out a couple of threads, so I'd like some 17.5's or 17's. I want to stick with rounded heads as it seems better if I smack my knee into them. Any idea where I can find something like this.
