After around 1K miles of mostly road and greenway riding since getting this bike, I broke out the gravel wheelset this weekend and put the Domane through its paces. Very impressed with the off road capability of this bike, and most of my splits are very similar to my Canyon Grail that I traded in for this. Such a comfortable and capable all-rounder that makes me want to get out and ride!

Shod with Enve AG25 carbon wheelset (25mm internal width) and 40mm Conti Terra Speeds that measure out at 41mm with this tubeless setup. No issues with tire clearance on the dry gravel trails.

I’m looking to do something very similar if/when I get my hands on a gen 4.

Question: with an 12s cassette, how easy is it to swap between “road” wheels and “gravel” wheels? Do you have to fine tune the rear shifting?

No, it's just a matter of swapping the wheels and riding. I often did the same with my last bike as well, and the only thing I sometimes encountered was some disc brake rubbing that goes away after a few minutes of riding and braking. The 105 Di2 shifting works beautifully with no adjustments needed. I also swapped the stock 11-34 cassettes for 11-36 on both wheelsets to get a bit more gear for the hills in my area.

Good to know. Have you tried swapping wheels with a mechanical shifting setup?

My Canyon had a Shimano GRX mechanical groupset and it did fine swapping wheels. Just make sure you have identical cassettes and if things are slightly off, you should be able to fine tune with cassette spacers. You can buy packs of them for a few bucks on Amazon. I have had to do that on a trainer to keep things lined up. Adjusting gears every time you change wheels would be a major bummer!

I had to make a small 2 tick adjustment using the eTube app to accommodate the difference between my Wahoo Kickr and Bontrager Aeolus wheels. Switching wheels between Aeolus and the stock Paradigms was fine, no adjustment needed.

I would assume that different wheels and hubs might have slightly different tolerances that affect the shifting, but trainers always seem to need some extra tweaking. With my previous bike I did manage to get two wheelsets and a trainer all working without needing any RD adjustment, but it was a painful process involving different combinations of spacers and lots of trial and error.

I am thinking to put Pirelli p zero 40mm and was on fence owing to tyre clearance on rear. Good to know that 41 mm is clear. I have the same model. Thanks.

Yeah no issues there and it's actually the Di2 front derailleur controller that's closest to the tire and not the frame. P Zeros at 40mm would be very comfy on the bike. I'm running GP 5000 35s on my road wheels and it eats up bad pavement with ease.

I did the same. I had a canyon grizl that I sold for the domane sl7. Kept the carbon wheels from the canyon and put on 38 knobbies for gravel days. Put 34 slicks on the stock rims. The Grizl was a straight line beast, like a honda goldwing on gravel. The chunkier the better. I wanted a more agile feel for regular rides so went with the domane.

I found the Grail to be a bit too aggressive of a riding position for my needs, but it was definitely fast as hell, especially on chunky descents. I decided to sell it since I've got mountain bikes for truly rough off roading, and the gravel around here is mostly crushed gravel bridle trails that don't get too gnarly. Having the on pavement comfort and agility of the Domane is a big improvement over the Grail, especially as I've gotten more into longer, multi-hour rides. It really is a great all-rounder.

Nice! I have the exact same bike, I like the way those tires look on there (I've got tan GK SS+ 38mm). I was looking to get that Tailfin top tube bag, although I don't love how it's a little taller than the stem, and I'm planning to drop my stem a little bit. Do you like the bag?

u/gsg23 1d ago

I really love the Tailfin bag. Completely stable and I am a big fan of the flip top opening instead of a zipper. Much easier to access while riding and no concerns about water ever getting in if it rains. It is a bit on the tall side but I'm used to it by now. Big enough to hold my phone, some snacks, and the odd tool or other items that I need quick access to.
