Road Cycling - how much liter can i go?

Here's the deal.
I have a merlin (not extra lite), dura ace, Rolf Sestriere 700c and other non high end components.

I do a lot of climbing and am wondering whether going with ultra light stem, bars, wheels, seat post, etc. is going to make that much of a difference.

My pedals and shoes are very high end; so the interface is superb.

TIA

You mean "lighter" ?

And to answer your question, whatever upgrades you add probably will not be worth it...unless of course upgrading your bike with expensive components is a hobby within itself :D

I don't know that wheelset.. that is normaly the first option to make a bike perform better. Honestly a pound or so does not make that big a difference.. figure you are pushing yourself on that bike and you far outweigh the bike no matter what.

If your doing a lot of climbing the super light bars and stems will not last as long and could suddenly fail on you; maybe not a problem if you got the money and replace those items every 2 years. The seat post should not be a problem using light materials except sometimes the seat clamps are not strong enough due to cutting weight to hold the saddle securely enough. But on all the above mentioned areas, any weight you may save would probably be less than 1/4 pound and this weight is static not rotating weight.

Thus the most important reduction of weight would be in the Wheels. I am not sure how much your Rolfs weigh but some people I know seem to like the Mavic Ksyrium Elite for a light but strong aero wheel, BUT they cost about $250 each wheel-but that's less than a lot of specialty wheels these days! If your on a budget you could build a set of standard rims using Torelli Master Series rims (425grams) that weight the same as Mavic Open Pro but cost about $20 less each, hook those up using DT Revolution spokes with 32 spoke rear and 28 spoke front with Dura Ace hubs and brass nipples (stronger than alloy for a mere 10gram weight penalty). By the way if your a big person you should go 32 in front and 36 rear.
