Thanks Hubert, that's exactly what I wanted to know.

Some photos on the scales of my new 9070 parts.

Question: No BC-9000 brake cables included with the shifters, and I can't find them in the UK at all. What would you recommend to use for the initial build (and would it be worth switching once the 9000 cables are available)?

Yokozuna cables are a very worthy substitute. I haven't used the new Shimano cables yet, but I found the Yokozunas to be superior to any other brake or shifter cables that I have ever tried.

Yokozuna are good but can be extra work to install depending on your config. The brake housing can be too big and needs some trimming. The length has to be perfect for some brakes too. Should be less sensitive with Dura-ace calipers though.

I was thinking mostly of the cable itself and not the housing. I have never tried Yokozuna's fancy housing (Revolution, iirc). Their regular jet-lubed housing along with their stainless steel cables are magic. They were the only thing that made my 7900 shifting acceptable, back before I went with DI2.

My DA C50 clinchers arrived today. Look great, just holding out for better weather before I run them on the bike.


Can you stick them on a scale and post results?


Haven't got a scale unfortunately.


Mine have arrived too and I do have some scales. I'll post the results later.

828g for the front, 1003g for the rear out of the box. So 1831g for the set. Shimano stated weight for the set is 1672g so these are 9.5% over.

This set is gonna have to go back though. When rotating the front wheel, I can hear loose material rattling around the inside of the front rim. I managed to shake some out from the valve holes but can't get all of it.

Here are my WH-9000-C50 CLs

note that i removed the stock rim tape and replaced them with a single layer of stan's yellow tape. Original weight is what's pictured + 10 grams per wheel.

Tried the yellow tape as a longshot experiment, worked out great!

(1 layer stan's tape = 5 grams per wheel ; Orig Shimano Tape = 15 grams each)

so stock weights of 1740-1831g vs 1672g advertised.

Thanks, appreciate the weights. I was hoping they'd come out closer to advertised.

Anyone install a 9000 crankset with a King bb? Do I need the thin spacers that king provides? It seems to have play in it.

It shouldn't.

That's more like 1710g. Shimano advertises weight for the wheels sans tape. Yep, still overweight.

at 1710, definitely not featherweights. but you do get an alloy brake track if it's any consolation.

(i find the 'disappearing spokes' cool too) :wink:

Once again Shimano demonstrates its inability to work carbon.

Either that, or their commitment to put out rock solid products with ample safety margin, targeted at average Joe, who's not very interesting in weighing things.
