Cyclocross - Felt F1X diet plan ideas?

Not sure where to post this, but cyclocross seemed right because you know the most about 'em

UPDATE: It's on 2008 Felt F1X, didnt include the year! doh

Let me cut to the chase:
I am looking for the biggest payoff replacement parts to make my F1X lighter for on-road commuting. I know that u usually start with lighter wheels, but the ones it came with seem pretty decent to begin with. Anyone interested in my backstory, keep reading.

I was looking at road bikes for commuting to work, I have a full suspension mtn bike but it was just too inefficient to make the ride enjoyable. after talking to a lot of bike guys at work i ended up geting a cyclocross because i'm not used to the super agressive position of a road/tri bike and a cyclocross seemed like a good cross over to the road bike world.

I got the F1x used of clist and it came with road tires which was great cuz the nobby tires would have been the first to go since this is going to be 95% on road use. I've commuted 5 times and its AWESOME!

I added a Topeak MTX aluminum rack and DXP trunk bag which added ~4lbs but has awsome space and usability, and is much more aerodynmic on my big downhill ride into work but considerably heavier than just using my jansport bag.

Thanks for the input!

The wheels are really the only place where you're going to notice weight savings for the way you're using that bike, and even there it's probably going to cost you a lot to get not much improvement. It looks like the 2009 F1X had 32H Mavic CXP22 wheels. You could save about 50 grams on each wheel by switching to Open Pros -- maybe more if you got something with lower spoke count. Your wheels probably weigh around 1800 grams. You wouldn't want to commute on wheels that weighed much less than 1700 grams. Lighter and/or better tires might be a good investment, depending on what's on there now. Of course, there's always a trade-off between flat protection and light, fast tires.

If you're willing to deal with the four pound rack and trunk bag, anything else that doesn't rotate will be minuscule by comparison.

I say just enjoy the ride.

I will agree with what AndyK said. My nice wheels on my commuter/road bike are king/open pro with 36 spokes. Not because I am very heavy just because they offer more durability when I ride loaded. I have ridden lighter spoke count wheels alot and can not hardly tell a difference.

The motor being stronger will always trump nicer gear so put that money into doing some big charity rides or something.

Haha, i agree nubcake. I have myself on a diet as well. loose 4 lbs off the gut and i wont even notice the bike rack anymore!

Panaracer Pasela TG foldable 28 mm or the Specialized Borough Elite with kevlar bead are about the lightest road tires with flat protection. I saved a lot of weight by switching from Cannondale MTB shoes to SIDI Mega MTB shoes, but this was done to get the extra width. If you have more than 3" of seatpost in the frame, you could cut that off.

i checked the seat post, maybe 3-4 inches in the frame so not alot to do there. I have Continenital Contact (safety system) road tires on it now, pretty darn good compared to my mtn bike tires and the nobby one's the F1X comes with but i'm sure there are lower rolling resistant tires and lighter ones out there. my shoes are similar to the shimano SPD SH-M076, pretty light.
