Moving from 10 speed to 11

Kind of a noob at this so forgive if this is a really basic question. I did a search but could not find the answer and I got different answers from the LBSs so am super confused. If I am on a 10 speed shimano cassette now ‪and want to upgrade my mechanical setup to new ultegra di2 which is 11 speed, do I simply change all my current zipp rear wheels cassettes and away I go? Unless the spacing between the cogs are reduced I would have thought that the width of the combined hub and cassette unit would be wider in a 11 speed config as compared to the 10? Hence a hub change is required?

It depends on the vintage of the Zipp wheels. If they are Firecrest then at the worst the wheels can be sent to Zipp and upgraded. If they are 2013 they are probably already 11 speed wheels you would just need to take the spacer off that is behind the 10 speed cassette.

Thanks. I bought them from LBS when I picked up the shiv last year so I might be out of luck in terms of the vintage. How do I check anyway?

Two clicks in on my original link…

Post a pic of your rear hub here. Also a shot if the decals.

Keep in mind that you can run an 11 speed cassette on a 10sp freehub if you take the smallest cog off. That fix will work until you’re able to upgrade your wheels.

You’ll need a lockring specific to the cog that’s the new smallest cog. (probably a 12)

Thanks a bunch Kevin. I am based in Malaysia so I have no idea how long it would take for my local guy to do the conversion. Quite a bummer that discs cannot be converted. Have been looking at picking one up second hand but I guess it will have to be new to make sure it is DI2 11 speed compatible

Hello Fast Freddy and All,

Not necessarily all wheels need to be new to be 11 spd compatible.

I have an older Mavic clincher disk (for sale - see classifieds) that is 11 spd compatible - just slide off the 10 speed washer and away you go.

There may be other wheels that are compatible …

Cheers,

Neal

Funny thing is that most wheels have been available for some time with a Campagnolo 9/10/11 speed freehub option. For wheels that you can’t get a Shimano/SRAM 11 sp conversion, check to see if you can get a Campagnolo freehub installed and run an Campy 11 sp cassette. Spacing is close enough as to be compatible with Shimano/SRAM 11 speed.

At least for Zipp, you have to install a .25mm spacer behind the freehub.

Aha…here’s thelink to converting 2009+ Zipp’s to Campagnolo: http://www.zipp.com/_media/pdfs/technology/188_campy_conversion.pdf

Before you give up, there is another option.

With a very simple trick (and one that is totally free–you don’t have to buy any extra lockrings, but of course you do have to get an 11 speed cassette), any generation of a standard 8/9/10 speed rear wheel or disc can be made compatible with a shimano 11-speed drivetrain. No need to re-dish or rebuild the wheel, or change cassette bodies, or compromise your shifting by using another brand of cassette. You just have to be willing to use a shimano 11-25 or 11-28 cassette.

Hi Greg. I actually already have the 28 from a hilly HIM I did recently. How do I do it?

Sure, just take a look at this. Works great.

You can also convert your current 10spd Zipp free hub to Campy and use Campy 11 cassettes. Zipp is pretty expensive to convert- $300/wheel if they’re not 11spd compatible. They have to go back to the factory to have it done. A few people are able to get away with using the 25 and 28 11spd cassettes on their 10spd wheels, but it depends on the frame and the clearance at the hanger/dropout area.

However, if you’re on a budget- just use your existing Shimano 10spd cassette. It works 98% with only minor, minor noise in a couple gears when adjusted. You will have to “block” a gear out with the limit screws in the derailleur. After that, away you go. I wish I would have known before I sold all our nice 10spd wheels…
