So, I'm doing a new project based on a 1998 Klein Quantum Pro in the green/purple chameleon paint so it's a US built pre-trek fuesalage with the Aeros carbon fork.
It still has the MC2 cockpit/headset combo intact on there and it's all in very good condition considering the age. No play and no coarseness.
A minute ding in the TT and some small chainsuck rubbing on the left chainstay are the only things I can find that is wrong with the frame.

So a few thoughts.

I want to keep the MC2 cockpit because it looks rad and it's very light.
I want to go mechanical because I'm not ready for any electronic bits just yet.
I want it to have a compact chainset
I want it to have a light clincher wheelset in carbon
I want it at 6.5-6.8kg.

My budget is around $2k all in.

What are my options? Second hand bits no doubt.

I was thinking maybe a Rotor3D24 with Praxis Buzz 50/34 rings with Dura Ace 9000 front and rear mech + shifters, or is there better bang for the buck pairings?

Hit me with your knowledge!

Cheers!

I love these old bikes. I used to own one of these many moons ago and would love to find one again. They were ahead of their time.

Indeed they were. MC2 stem and headset is just brilliant in it's simplicity but I've read that it can break on you.

But then we have Reset Racing to sort that issue out I guess.

My Klein with dura ace 7700 and 1000g tubular (bare) wheels was 7 and bit kg. that's with a grammo quill stem as well
So your weight goal is attainable with that budget ut with clinchersit will be hard as carbon clincher in a 1100 to 1200g range are going to eat your budget and still be heavier than cheap tubular wheels.

Yeah you're right, I might need to go tubular for this build. First one in that case. I need to look at the sales threads when I reach 40 posts :D

Ultegra 6800 can be had for cheap but is a great workhorse group.

Try to get a used SRAM Red gruppo. Add some light brakes and an nice chinese wheelset. Nice Frame!

^^what he said.
I prefer DA myself, but being a american frame, I see more fit a SRAM groupset.
Wheels, I also can't be bothered with tubulars, there are plenty clincher wheels around 1300gr on ebay below 500usd,40mm deep would look great.

Also, keep the components low profile, so that gorgeous frame really can stand out!

Surely it has to be DA 7800, I mean come on, how sexy would that look!? Sram Red is boring unless you tune it 8). Add some low profile alloy tubs with gumwalls and it'd be perfect.

Cheers lads for all the input. I'm currently looking at getting the DA 9000 gruppo because I think the logos with the green/purple offset on black/silver will look neat from an aestethic viewpoint. It's also 1960gr according ccache which is another factor.

I'm also wondering if anyone knows if the Novatec Jetfly HD wheels have decals that can be easily removed.

1430gr without rimtape/skewers is not half bad for a 450euro wheelset.
