Bargain Road chainset - 10 speed but will work with 11 speed kit. 53/39 and 52/39 with 175mm cranks available at time of posting.

6800 is 11 speed
175mm is very rarely needed for most
This is the 6600, not 6800

Corrected to 6600. I have 175mm cranks on my bike but I'm lanky.
My ancient Campy Record cranks are 177.5mm great for the hills less so for spinning.
Cant see why the chainset should relate to the rear number of cogs so long as the teeth pitch is the same , might be wrong?

11 speed chains have slightly different width dimensions to 10 speed ones but yes for the chainset this is largely irrelevant. You can happily run 11 speed chain/cassette with a 10 speed chainset - indeed I do on one of my bikes.

11 speed cassettes fit on the same size mount as 10 speed. To achieve this they are fitted closer together and consequently have a narrower chain. Teeth for a thicker 10 speed set-up might not play nicely with 11 speed.

On the back, yes, if you ran a 10 speed chain on an 11 speed cassette. On the front they are practically interchangeable.
Sorry for noob q, but would this chainset be compatible on a tiagra 4700 system?

Hi, yes it will work perfectly - both are Shimano 10 Speed.
