Would like to know more about that one.
You know, the usual stuf.
If you are not interested in a Junior 11spd FW - these numbers will seem high. If you are, you know they are very light.
Right now...it is the only one (as I have been told) and it will be used tomorrow for warm up, then we switch to the alloy modified version. There should be a bunch more of them in steel and then all alloy available in a few months. I cannot get a good answer on why the 18T is skipped. We speak different languages. I don't like it, but that is what it is right now. I have hunches, but know answers.
This is 200g-210g - my scale is good for +/-10g. It is the exact same as my 10spd Dura-Ace Ti / Ultegra combo.
My Michie SuperType 14-25 is all alloy, individual cogs around 190g
My Michie Steel - 14-25 individual cogs is near 400g
My RECON Alloy that I milled and added a 14T steel is < 140g. My son wants to race with this. We know there are risks.
I expect the future RECON alloy 14-25 to be about 120g.
All the above weights unverified of course.
I would not ever use anything but one piece if they are available in the specs needed. For the extra $50-$100 you save 50g-200g and pick up something much easier to work with.
Shift quality - my kid tells me they are fine / great. I drill down, but that is the best I can get. IMO this will wear in after 500 miles and be perfect. The alloy I did is picky in the indexing and the new RECON alloy I expect to be fine.
We got rid of our DA 9000 and have nothing to compare to and do Friction Facts weird stuff, so I can't really give you an accurate comparison.
