So, given that I'm already so skinny my wife would kill me if I lost any weight, and that this race is really my only one each year - I train for it exclusively through the spring and summer, and finally that I'm turning 50 with in a year, and want to treat myself to something really silly - I thought of putting together a crazy light bike just for this race. And I don't want to buy anything new for it - just very light used stuff, so it shouldn't cost too much.
So here's what I'm thinking: I buy a used super light frame (maybe a Scott CR1 Limited?) and then turn it into a minimalist single speed, with no derailleurs, no brakes, tubular tires on super light rims, and shortened handlebars.
What do you think? Could I get down to 8 or 9 pounds total? Is it hard to use a standard carbon frame as a single speed - should I replace the dropouts so they're more horizontal?
As far as going to SS you need to figure out if there is a 'magic gear' to tension the chain right or you have to run an extra pulley tensioner. personally though, I run a different gear at 12% and 22%
Most riders on Mt. Washington use their gears, but I've found over the years that I use maybe 3 cogs, and they're all close to each other (22 up front, and I use a 21, 22, 24 in the back). I figure I could make it with some difficulty using a 22-22 combination.
And the climb is awesome, because not only is it really hard in ideal conditions, but most of the time it's cold, windy, and sometimes rainy. And the wind can howl on this mountain - I've seen people get blown over near the top.
I'd consider using down tube shifters with 3, 4 or 5 cogs made from aluminium and pvc pipe as a spacer across the rest of the freewheel.
Buy a mid-range derailleur (athena, chorus, ultegra, sram-equivalent) and modify the hell out of it!
Add lots of drillium to everything...

Cool project! 8-9 lbs should not be too hard to achieve. I've done that race a couple times and I think you could get away with a single speed as the grade is very consistent (except for the first 100 yds and the last 100 yds). That said, if I did it I would probably go with a single chainring up front and gears in back: the weight penalty wouldn't be all that big, and that way you could easily use the bike on lots of things. I would also probably put on a front brake (only) for the same reason.
As for the dropouts, with vertical dropouts you can try different front/rear cog combinations and could probably get something to work in your ideal range (since you have flexibility up front as well). However, with horizontal dropouts you could use whatever chainrings/cogs you wanted so it certainly would be easier.

I'll be there in February!
I'm open to all suggestions on how to get a super light bike. Remember though, every pound I take off (current bike is around 17 lbs) means about 40 seconds faster. I normally do around 75 minutes, so every second matters!
