Upgrading from 105 5600 to Ultegra

Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Upgrading from 105 5600 to Ultegra

Hi all. Apologies if this has been answered but thought Id get some of your opinions.

I current have a 105 5600 10 speed on my Orca and was wondering if it is possible to swap out the crank for a Ultegra 6700 10 speed? Would the 10 speed Shimanos generally be all interchangeable for the cranks?

In terms of a bigger picture I am looking at one day giving the bike a new group set for something new Would it be better getting the 6800 Ultegra 11 speed or the newer R7000 105?

Thanks!

Yes, you can directly swap a 6700 crank for a 5600. Not much point unless you need a new crank. As for the new group, 7000 would be a better choice than 6800, IMO. They made significant improvements with the second generation 11 speed. Also, 7000 is current, will be much easier to find a new group than 6800.

Swapping out a 105 crankset for an Ultegra crankset is pretty pointless.

Unless the 105 crank is damaged or you want compact its not worth it. I changed to a 105 long cage for more cassette range recently. May be could have put a Wolf thing on the short cage Ultegra. Best thing is save and get a disk brake bike. Keep what you got for a spare bike.

couldn't agree more. Not really much upgrade just to do it. Both are good sets but not gaining anything IMO to switch.

As for putting an entire new 11 speed group on the bike, you just need to decide if weight savings of Ultegra over 105 is worth the additional cost to you. I run both groups and sometimes will mix them up. My main bike right now has a 105 drive side crank/spider with Ultegra 52/36 rings and a Ultegra left crank.

The story behind that is a little more than I'd like to type at the moment.

But I'll bet your non-drive side is waaay faster. It probably gets home before your drive side.

Boy, no kidding. There's no performance or functional improvement to this.

I think the chance for crank breakage, although low, actually goes up with this change.

You might be on to something there. Previously I thought it was just because that's the side the house is on when I get home. <grin>
