Lightweight RD carbon fibre rear derailleur

[GrahamB]

RD Carbon Fiber 120g $1149.90 $9.52 per gram
Red 153g $299.99 $1.60 per gram
Record 187g $279.99 $1.49 per gram
DA 180g $159.99 $0.89 per gram

Wrong metric... this one equates a heavy, expensive part with a light, cheap one. An RD that weighed 1kg and sold for $890 would score the same as DA
You want weight SAVED/$, so you need to start with a reference point like DA or Ultegra...

Well I am very happy that I did not have to pay $300 for my Sram Red and I am glad that it did not come in at 153 as posted.

$216 for the Red Derailleur and 145g stock.

[jjmstang]

My Red RD was 145 stock also. Maybe if you pay more you get more

Here is my 122g Sram Red RD. I am getting a new part built at work in the machine shop but I think I might only get it down to 121g.

style points to djconnel for using "mass" instead of "weight". You made this physics geek smile.

This is WW, not MW...

This is WW, not MW...

Then you should be measuring newtons and not grams

I posted this in another thread already, but here's my 122g SRAM Red rear derailleur. About the same weight as the LW, but much less expensive:

A similar job can be done with a Force RD. Here is one that Boonen (from w.w's and FWB forum) did for a friend of his....119g.

how does it shift ?

[Sybarite]

Early prototype shifting with 7800 was a bit slow. Had to click and 'hold' shift for a little while more than usual. But this was a proto.....

After the shock of seeing Hawkpower's Scale (Heinz Wittman)with a LW RD1 and a 11-32 cassette, I want to know more of this rd...

I have read tiso 11 speed rd topic where Gold Knight says that is 11s capable...any info? anybody knows qhat modification should be done?

[wshiong]

Hi guys.

Anyone know this RD support 11 speed ?

Some company said it support up to 10 speed only.

But Lightweight claim it 11 speed compatible.
