When I was looking the Propel was too small for me and I got the CF SL 8 Disk Di2 with Ultegra. Was far cheaper than current Canyon prices being pre Covid though. At 195cm only got the XL as well rather than XXL and right choice (well i like the slightly smaller frame and reach) Id buy a Canyon again if I needed another decent bike. Had to return it as well due to Di2 failure but they fixed it, took less than two weeks and all free postage. Customer Service was faultless, I guess the Giant Store 3 miles from home would have been easier though
I’ve been looking at a Canyon this year myself and the one you want can be bought from the Canyon outlet store for around £500 cheaper. I was looking at around £1k saving on an ultimate.
I’d managed to swing it with the Mrs by us having a weekend away in Cologne, driving there but then spending an extra night and picking the bike up at the outlet in the car, bundling the Mrs back on the high speed train to London, changing at Brussels.
This worked out at just over £600 for me, so still a saving and some brownie points though obvously a cost for you.
The bike comes readily assembled for you at the outlet so no boxes to raise the eyebrows of customs, though I’m sure you’ll declare it anyway.
If not, an alternative to both is an Orro bike which seem to get good reviews.
