Di2/11sp upgrade advice
Posted: Sun Sep 01, 2013 7:54 pm
This is kind of following on from my other thread here about upgrading 6770 to 11 speed but kind of not so new post: http://www.bicycles.net.au/forums/viewt ... 12&t=67538" onclick="window.open(this.href);return false;
I tore an abdominal muscle while snowboarding about a month ago so I'm off cycling for 6 weeks or so and figured it was the best time to build, replace, upgrade, etc my weekend ride. I've just recently got my hands on an Avanti Corsa DR frameset which I am in the process of building up. I had finished the build with 6700 shifting and 9000 chainset and brakeset but then I had a good offer to sell a full 6700 groupset so I pulled the FD and cassette off the bike. So I now have some brand new shifters and an older RD on it and I'm trying to decide what to do. I've decided that my ultimate goal is to get to an electronic 11 speed setup and I've identified four options to get there. I've been trying to get my head around which will work best and I figured I'd put it out to the forum and see if there is an obvious issue or benefit to any of them that I'm missing. To make it even more complicated, I want dual shifting options with standard and TT shifters.
Option 1: 6800 now and then upgrade shifting to 6870 when it drops in Jan(ish). This would involve buying a full 6800 gruppo and selling off the crank and brakes now and then replacing shifters, RD and FD in Jan along with all new wiring. I'd also have to upgrade wheels now as my Bracciano's are the old version and won't support 11sp. This gives me 11sp in the short term and electronic 11sp in six months.
Option 2: 6770 now and then upgrade RD to 6870 in Jan. This would involve buying a full 6770 gruppo and selling off the brakeset. Then in Jan I'd buy the new 6870 RD and a new cassette and upgrade wheels. This gives me electronic now and 11sp in Jan.
Option 3: Assuming that you can convert 6770 to 11sp by installing a 9070 RD (see post above) then I could just go all out and buy 6770 gruppo and upgrade RD to 9070 along with wheels now. This gives me both now.
Option 4: Complete the build in 6700 and just wait the 6 months until 6870 is released. This gives me neither now.
Basically I figure that minimising equipment that is purchased now and then sold off after 6 months use seems the most sensible which would point to 3 but that option is the most expensive which kind of evens it out. Option 2 looks promising but then I'd end up with 6770 instead of 6870, although only for the shifters, FD and wiring. Option 4 seems good, especially given that it looks like I'd be able to order the wiring the way I need it to run TT shifters, rather than having to replace the default 6770 wiring harness; but I'm impatient and want to do something now!
On a slightly unrelated note, starbike.com appears to be taking pre-order on 6870 already (http://www.starbike.com/en/shimano-ulte ... e-routing/" onclick="window.open(this.href);return false;). Does this mean that the release on this will be sooner than expected or are they just REALLY keen?
