There is nothing in this world like a shift on a Shimano front setup. Even their old mechanical stuff worked like butter, but the Di2 setup is nuts. Shifts every time, quiet, smooth, can do it one-handed, it's the best.
The crankarms themselves I have no issues with, even with the recall going around. The rings are where the magic happens, and it's worth it to me to not think twice about a front shift, or grinding it out a bit more in the big ring just to avoid that dreaded potential drop from other setups.
Great crankset. Catch a sale and treat your bike.
For winter weather I strongly recommend winter shoes. I tend to have cold feet and these winter shoes make biking in mid 20�F temperatures much more tolerable. I wear wool socks and these shoes and can last for about 2 hours before taking a warmup break. I had tried regular shoes with shoe covers and chemical hand warmers, and these shoes are much warmer. I wear these in the same size as my summer Shimano shoes and find the fit, with moderately thick wool socks, to be good.
Replaced the BB on my 4 year-old / 19,000 mile Specialized Roubaix. I opted for the Park 59.3 BB tool rather than using an adapter. I replaced my crank at the same time because a full crank on sale wasn't much more expensive than the regular price of the big chain ring that I needed to replace.
I hadn't done a repair like this on this "generation" of Shimano drivetrain technology. It was surprisingly easy to do. If you have moderate wrenching skills and access to YouTube, this is definitely something you can do at home.
This dropper lever is really nice! I started with the more common lever on my gravel bike that allows a pull/push from different positions. It was stiffer, and with slightly arthritic fingers, I had to get my hands in a slightly awkward position, push the lever, and then change my hand position. I could do it, but I avoided it if I could. This new lever is so much easier and more convenient to use! Even with a sale price, it still stings a bit, but I don't regret it!
