What is the width of an 11 speed cassette?

Chains for 11-speed systems are around 5.4mm wide on the outside, vs. around 5.9mm wide for 10-speed ones, so that’s 0.25mm narrower from the center of the cog tooth to the end of the chain pin on each side.

Shimano 10-speed 3.95 mm 37.2 mm (note)

Are 10 and 11 speed chainrings the same?

There’s no meaningful difference between 10 and 11 speed rings. Instead of making the cogs narrower, Shimano thinned down the spacing between the plates of the chain.

How do I know my freehub size?

Place a tape measure across the face of the exposed wheel hub, which it protrudes out from the center of the drum brake assembly. Take the measurement across the front of the hub, which is the diameter of the hub. Make sure your tape measure intersects the center of the hub.

How do I know what freehub I need?

Knowing What Freehub You Need

  1. If you have 10, select a Shimano/SRAM freehub.
  2. If you have 12 gears, select an XDR freehub.
  3. If you have 11, look at your crank.
  4. If there is one chainring up front, select an XDR freehub.
  5. If there are two or three chainrings (gears) up front, pick a Shimano/SRAM freehub.

Can 10 speed wheels be converted to 11-speed?

To upgrade a bicycle to an 11-speed components group requires your existing rear wheel to accept the 11-speed cassette. Luckily, many common and not-so-common wheelsets, as long as they’re at least 10-speed, can be upgraded to 11-speed by purchasing a new cassette body.

Can you put an 11-speed wheel on a 10 speed bike?

Use spacers on the 11 speed wheel to put a 10 speed cassette on. See your hub manufacturer’s page for details, but its normally a 1.8(5) mm spacer (which comes with the hub, but you can buy separately) and a 1mm spacer (sometimes; which you’ll get with the cassette).

What’s the difference between 10 speed and 11 speed?

10 speed chains are slightly different from 11 speed. 10 speed chainrings are slightly different from 11 speed, but in most cases, you can simply swap out the chainrings instead of buying a whole new crankset. Some rear hub cassette bodies are only designed to accomodate up to a 10 speed cassette.

Are all 11 speed cassettes the same width?

11 speeds. Sprocket width is the same as for 10 speeds, so 10 speed sprockets can be used, provided that 11 speed spacers are used. Sprockets are 1.6 mm thick, spaced at 3.74 mm (road), or 3.9 mm (MTB).

What’s the difference between 10 speed and 11 speed freehubs?

When FLO started and 11-speed was in its infancy, 10-speed and 11-speed freehubs were different. In order to add the additional gear on an 11 speed freehub, more space was added to the freehub. The image below shows a 10 speed and 11 speed freehub side-by-side.

Do you need spacer for 11 speed freehub?

That spacer allows you to install a 10-speed cassette and run a 10-speed groupset, only now you can swap a wheel between a 10 and 11 speed bike simply by adding or removing a 1.8mm spacer, also known as a 10-speed spacer.

Are there any 11 speed road bike hubs?

Thanks to one of our inside sources, we scored this outline of DT Swiss’ new 11-speed road hubs. If you recall, all of their 2013 road bike hubs will be 11-speed, and there are rumors swirling that Shimano and SRAM will offer an extra cog soon. This diagram specifically calls out Shimano, which means it’ll fit SRAM, too.
