Hello weight weenies,
After some basic work on my SuperSix Evo, I decided that I wanted to do a really light build! This build will be based around an aluminum frame, the specific brand is not yet decided. I haven't seen a Emonda ALR build under 6kg, so I might go down that route. Another option would be a CADD10/12. The components on the bike are not going to be the lightest available, but I will tune the crap out of them! I will try to update the thread regularly, and will be putting together a spreadsheet in the coming days.

With my intentions explained, here is what I have done so far: The groupset will be SRAM Red 2011, and I have begun work on the shifters. These are not completely done, and would like suggestions as to where to remove more material from them. ImageImage

Do you have an envisaged/target final weight?....... <6kg perhaps?

Spinning knives... I actually like discs and had thought of that. But I ride for a Trek dealer!

Did some more tuning on the lever blades today. Got the right down to 14g and the right to 14.2g with clear coat. I finished the left unit by cutting out the shift paddle. I then put heat shrink over the paddle cutout, as it is ugly. I'll finish the right tomorrow, and get new mounting hardware. ImageImage

I have a 1000g aluminum frame that I want to make into a 1 X 10 sub 6 build. This gives me some great ideas.

Glad your interested! Definitely gut your left shifter- saves about 30g! I'm using this bike for day to day riding and need a 2x. I thought about it being a crit bike and was going to go down the 1x road.

Are you able to just go with a non shifting left lever and tune it even more.

Yep, check out the "Removing the Double and Tap from SRAM shifters" by CX Magazine. There are step by step instructions!

I have done that before on other builds but feel that it could be lighter just using a non-shifter version.

Have you thought about tuning some Carbon Record levers.

Image

I can't remember the weight on these but they were fairly light.

I believe that the sram S-900 ones come in at 244g and tuned could be fairly light.

I'm actually pulling parts from my cracked 'Cross bike and tuning them! I'll buy some things, but am trying to keep this as budget as possible.

I finished tuning the brake levers, and they came out to 230g without brake hoods. This is not as light as I would like, but I have not yet replaced the clamps. Here they are on some random bars I had lying about: ImageImage I'm very pleased with my he way the heat shrink looks of the shifter paddle cut outs!

Clamps:
The stock clamps are several pieces, and they are quite heavy, at 15.6g a piece. Here one is:Image i have SRAM Red 2013 on my SuperSix, and tried that bikes clamps. They came in at 13g, and work with my 2011 shifters. I'm contemplating buying a pair and tuning them, or looking for an aluminum option.
