I can answer in general terms.

You should have no problem with an upgrade to 11-speed that just involves shifters, cassette and chain if you wish to do so in the future, so it makes sense to go with an 11-speed compatible wheel now, even if you don't do the rest.

An 11-speed chain is the same internal width as a 10-speed, so the chainrings don't know the difference. It is marginally narrower because of thinner side plates and shorter pins.

 

Thanks bikerjulio. That's great info! Any idea if the ramping on the chain rings for a 10-speed setup are different from those of an 11-speed? My assumption is that they're the same... but well, you know how that goes.

 

It's not the ramping that is different, it's the spacing between the 2 chain rings. But using a 10 speed chain ring should work fine for an 11 speed chain since people are using 10 speed setups on 9 speed chain rings.

Are you saying that because you know for sure. Or is it an assumption?

 

The only spacing I am aware of is the difference between shimano rings and non shimano rings. I've used spacers on the praxis rings to compensate. But I am not aware of spacing differences between 10 and so called 11 speed rings. In fact I have yet to see anyone reporting a physical difference that can be measured.

 

I don't remember the exact spacing but it's millimeters.

 

Really? That's surprising since the difference in outside chain width is 0.4mm (that's zero point 4 mm).

 

The weekly question is back!

I have tried it both ways, 11 speed crank with a 10 speed drivetrain and 10 speed crank with an 11 speed drivetrain. I would say both work perfectly, with perhaps slightly better shifting with the 11 speed crank/10 speed chain (10 speed drivetrain) over using an 11 speed crank/ELEVEN speed chain (11 speed drivetrain, ie spec)!

 

But regardless of the spacing, how small it is, the 10 speed crank will work fine with 11 speed chains.
