|I'm thinking of doing an 80km time trial in a couple of weeks, mostly for training benefits and general kicks. About what intensity should I try to maintain? I'm thinking about 5 bpm below my lactate threshold heart rate. Input? Thanks.|

|If you stay below your AT, and keep enough sugar and water (and trace nutrients) in your body, supposedly you could ride indefinitely. As long as you have a good handle on what your AT (or LT) really is, it sounds like a good plan.
Have you tried this in training? Wouldn't hurt, even if for only half the distance.
|Thanks Doug. Another Question||Jon Billheimer|

|I haven't done any extended sessions like that recently, but did do some of these kinds of rides a few years ago when I was training for a double century. If you can keep from going into overtraining, they make you monstrously fit. I know the theory about fuelling the aerobic engine. However, it never works that way in reality. There's all kinds of speculation why. One is that central fatigue sets in, i.e. hormonal and neurotransmitter deficiencies in the nervous system. Who knows? |
BTW, even with a 2-lb. Bianchi frame, how did you ever build up a bike to weight 14.1 lbs.? And did you experience any component failures?

|I know what you mean about the fatigue. Also, the basic premise of having an ample supply of all essential nutrients is actually pretty tough to meet. Plus, muscle fibers just get irritated, causing discomfort and reducing power.
The Bianchi: the frame and fork (fork is very important) are very light; DA downtube shifters and non-STI brake levers; DA crank, bb, derailleurs, cassette, chain, with full SRP Ti and Al bolts; SLR 138 gram seat; USE Alien carbon seatpost; Easton carbon bars; ITM Millenium stem with Ti bolts; one 2mm carbon spacer; Velocity Arrowhead rims, 15/17 spokes, American Mfg. light hubs, Speedplay X/1 pedals; Cane Creek single pivot brakes with Ti hardware; minimal cables; Supersonic tires w/ Lunarlight tubes; that's it!
All this stuff is pretty straight forward; had some trouble with the rear wheel staying true, but fixed now. I would not use this as a road racing or all around bike; it's pretty much for hill climbing in special events that allow support and bike swaps.

|Doug, if you don't mind and please pardon me if you do answer this question? How much did it cost you to build up a 14.1 pound bike? That's a serious investment! Kind of a dollars to grams ratio, I guess.
That bike must climb like a dream.

|I built this one up over 2 seasons, and the bike has been in at least a dozen permutations.
It's really not that expensive. In fact, if you were starting from scratch, not much more than an off the shelf bike. The only outrageously expensive parts were the SRP bolts, at about $220 total, which saved about 90 grams over all. The Easton handlebars are a bit expensive, about twice a 'normal' bar.
The EV2 frame and American Classic wheels ( http://www.amclassic.com/wheela.htm ), the two most significant components, were actually pretty cheap, at about $1000 and $500.

|I find it fun to build a bike up from scratch. Instead of relying on maunfacturer's spec, and to be able to pick every part as you would like it to be. I bet it was entertaining just to weigh (no pun intended) you options here, and build up the bike as you saw fit. It's a sublime thing to see a bike that has been created by your own personal tastes for the purpose you wanted it to fit. Building it yourself is half the fun.|

|You should see the Excel spreadsheets analyzing Campy, Shimano, and other parts by weight and price. Yes, I did a lot of research here. Most people don't understand that building a super light bike, or any other specialty bike, is a hobby almost independent from riding it, and a whole lot of fun. I've gotten a lot of use out of my gram scale and hanging digital scale. Has it made me faster? Not much.
Problem is, as soon as you get it built, someone comes out with some lighter parts, or you hear of something you never knew of before. From that respect, it's an expensive hobby.

|I wouldn't mind having a look at those spreadsheets if it's not a state secret. Sounds interesting.|

|Is it Excel sports that has the spreadsheets that you are referring to, Doug? I would be very interested in taking a look at that information if you could point me in the right direction.
Cycling is a great sport. Wrenching on bikes is a great hobby too. I enjoy building a bike up with the parts that I envision will create a great ride. It's also great to know that your machine is ready to perform at it's best. There is something relaxing about working on your bike, and knowing where the work will take you. The only negative about being into the machine and it's parts is like you mention, it does get expensive with all the new stuff that comes out. I suppose that I could spend my extra cash on worse things though, and I do feel that I get my moneys worth for what I get.

|If you want, I'll email you the Excel (as in Microsoft) spreadsheets. They don't have current information, but you could use them to plug in your own. Just give me your email address. Thanks.
