You know it's funny Extralite bikes have been around for a while but their light weight have not captured a whole lot of Pro Racing wins. Also by running ultra light weight drive train parts you are sacraficing smooth flawless shifting for clunky light weight shifting. Miss shifts equals lost seconds on the race course. Next I don't care what the advertising says but a 64 gram saddle will never be comfortable. If your body hurts you can't put the power into the bike. Speaking of bio-mechanics running light weight Extralite bar ends will help extract more power from your body and prevent your hands from going numb during racing. Next the wheel system, by going with ti spokes you putting a lot flex and wind up into the wheel system it's going be like pedaling a rubber band. Unless your feather lite your not got realize any performance gains there. For wheels I would recommend Stans new Olympic system or Industry Nine ultralites wheelset depending on your weight. As for the lefty check the axle crown height on the lefty vs the standard 100MM standard fox fork the bike was orginally designed for. If your looking for a lighter headset look at the Crank Brothers Directsets.

Been there, done that. Learned my lesson. Expensive parts are indeed lighter, and road parts and running 2x9 or 1x1 is indeed lighter, but once you get to a certain point, it becomes ludicrously stupid.

Anyone with cash reserves can make a 14lb bike.

Question is, can your body take it? ;) And can the weight-weenie parts take you?

Since we're talking about light, I would ditch that fox fork and go for a SID or Magura if you really want to make it light.

Limon.....What happened to your Exogrid RX and the Rue X??????? You had both had amazing weights at one time.
the Rue X I still have its setup with v brakes the exogrid I sold and regret selling now I really want a Ti X to make up for it, Ti X with carbon downtube by Rue would be perfect if only titus would sell me a front triangle with out a downtube, do you know the right people to get something like that?

Sorry, they don't do jack squat in terms of favors for me;) . Best to ask someone like BikerBob to see if he could pull a special order off like that. I wonder if you could get them to use a Isogrid downtube on an X for you.

you're probably right don't get me wrong the bike is going to be 100% rideable when I'm done. I been riding ti spokes for ever never had a problem with stiffnes but industry Nine wheels do look sweet. crankbrothers headsets look tiny on al headtube walls but perfect for steel.

the only thing that holds me back from going to a lighter fork is the no bob on 100x.
