If you were going to buy, or build up a new bike, and price was a secondary concern, would you go with Sram Red or Di2? (I don't want Campy simply because I have too many Shimano wheels, and cassettes to switch to different spacing.)

Weight favors Red. Bling favors Di2.

Shifting appears to favor Di2.

I know one poster on here replaced his Di2 group with Red.

Anybody else used both?

this thread should be good.

as for my 2 cents - i havent heard too many complaints about the top end groups, red, record or DA shifting poorly, so if red is :

a)lighter
b)cheaper
c)more reliable (strictly from a traditional and a availability/interchangeability of parts standpoint)

it would be a no-brainer for me.

Di2, although I'd be tempted to get Campy SR11 even though it's inferior in every way (except looks perhaps) just to have a Campy bike.

It's really not fair to throw price out of the equation. It is the main factor between these two.

I would go with Red.

I have 2 bikes with Red. Rode a bike with SR11, rode a bike with Di2. Conclusion is Di2 is best.

there is your problem, ignorance is bliss.

None of that junque for sure.

i have a serious question about Di2 - re:battery pack.

i see some of the bikes have the battery mounted below the BB, on a chainstay, under the bottle cage, etc.

are these battery packs totally waterproof, and if so, will they remain waterproof after repeated charging (presumably having to open some type of "cap").

What a weird leap. What's wrong with regular dura ace as am option?

Yes.

BTW, Campy sucks, just saying...

True. However, I think the price difference is dropping, and if, or when, I do this it would be to get a very nice bike that I'll keep for at least 5 years plus. So a $1500 price difference wouldn't dissuade me from Di2. However, if there's no real reason to go Di2, I certainly wouldn't mind pocketing the difference.

Hence, price is a secondary concern, not price is no object.

Nothing. My thought process was do something pretty high end, hence Di2. (I'm not above bling, for bling's sake.)

The weight weenie in me, however, is thinking going with Red, you could build something uber light.

BTW, has anyone noticed how overpriced SRAM Red is getting, esp. after last year's TdF?

A lot of places online sell DA 7900 for around the same price as SRAM Red now. Price/weight was one of the big selling points of SRAM Red over DA or SR11 (or at least I thought it was).

Campy. Both of my other bikes are Campy equipped and I'd like to keep it that way!

AX cranks, AX brakes, fiberlyte rings, Campy derailleurs/shifters, Recon cassette...easy!

Definately Di2, and I used to be a sram guy

I did a long test-ride on a Specialized Di2 bike. I didn't think the shifting was that much better than Red. Maybe worth $5 or $10 more than Red... which is why I'd never buy Di2.

DI2. It's so much better than anything else out there it's not even funny.

I don't own Di2 or Red. But it seems to me that people gripe about Red and not about Di2 (except for the price).

Sora would seem really good while riding around a parking lot.

Did said "long test-ride" include climbing mountains or shifting while in the drops?

Di2 is quiet for the most part. I ride with a guy who has it. I don't hear him downshift or upshift as easily as I do from manuel shifting. I still am a SRAM guy and would take Red. I think that DI2 will be more costly on maintenance down the road.

Given your 2 choices, Red. But I wouldn't buy either. I'd go Campy. Neither the SRAM and Shimano hoods fit my hands. Campy does.

Dura Ace...

DI2 for me. If you are a sprinter wouldn't you prefer Red for their tucked in shift lever function?
