Mechanical question: 10-speed cassette on an 11-speed?
I’ve not had any legitimate offers on my mostly brand new 2014 Madone (see My 2013 Madone is gone; Brand new 2014 Madone–for sale?). If I don’t hear anything by the end of the day I think I’m just going to keep it. I’ve got way too much else going on right now to worry about it. It’s a great bike, and will serve me well.
I have one misgiving about keeping the Madone, and it has nothing to do with the bike itself. I might be able to work around the issue, but I’m not sure if it is mechanically possible. It would be pretty easy for me to test it, but perhaps one of you out there might have the answer.
The Madone is a 10-speed bike, and my Plasma TT bike is 11-speed. My 2015 Zipp 404 Firecrest wheels are 10 and 11-speed compatible, and I use those wheels on both bikes. Moving the wheels between the two bikes is obviously no big deal, but swapping the cassette every time is a bit of a pain. Ideally I’d replace the 10-speed drivetrain on the Madone with an 11-speed, but replacing the entire Di2 DT is not exactly cheap.
So, what I’d like to do is set up the wheel with a 10-speed cassette and use it on both bikes–basically convert the Plasma to a 10-speed. I know I’ll have to swap the 11-speed chain on the Plasma for a 10 speed chain and re-adjust the rear derailleur, but I’m not sure if it would work? I figure I’ll have one “dead” or redundant shift click on the Plasma, but that’s no big deal.
Anyone know if this would work? I’ve never done something like this before and may be overlooking something.
