When I first got the cubes, the material seemed a bit flimsy and did hold its shape. However, upon using them every day, I find they are perfect for my needs as the flexibility of the material allows me to be flexible with what I pack. The larger cube holds all of my clothing needs, the medium is for my tools, medical kit, etc, and the smallest is for snacks. Perfect! You could probably come up with your own version of pannier bags. But because these are specifically made for my Ortlieb panniers, they work better than a makeshift version.
I deliberated between different smart trainers for far too long and chose the H3 based on reviews and the fact that it's one of the few Trainer Road recommendations. I couldn't be happier with it. Pairing and updating went smoothly. It works great in both ERG and 'regular trainer' mode. It's an order of magnitude quieter than an old rear-wheel trainer, which I'm coming from. It's not a big deal connecting and removing the bike. Two months in, zero complaints.
Has been a great trainer with only a couple instances of frustration which may just be down to connectivity issues. Have had a couple brief instances where the tacx lost a connection when riding on Zwift but reconnecting via the app remedied the issue. One time, after pausing a Zwift ride, the trainer would not reconnect, no matter what I did. Turned everything off, including my wireless router to reboot Zwift/WiFi connection, and nothing worked. Unplugged the tacx overnight and it was back to normal the next day. I've not had that issue again, but I was a little nervous. That was about a month ago, and I've been using this 5/6 days a week since without any other issues, so I'm hoping it was just a hiccup.
Outside of that, the Zwift erg mode communicates well with the tacx and is a great upgrade from a wheel on smart trainer. I've been enjoying it.
I was on the fence about getting the single bottle holder because it blocks (on my bike set up) the use of a traditional saddle bag and I don't like filling up my jersey pockets with all the 'just in case' tire repair stuff on top of nutrition that will be in there anyway. This has just enough room for the essentials - I have tire tools, a tube, 3 CO2 cartridges, a patch kit a multi tool and a CO2 dispenser head in it. You do need to be very deliberate about how things are oriented and placed in it to maximize what it will hold. It's not in the way and seems to be an aero design. It will definitely make the grip on the bottle in the holder quite snug. I left a full bottle in it over night to help stretch the bag a bit.
One thing nice about the tight grip is this will now keep a 25oz Camelbak style bottle in there without ejecting it on bumps, it wouldn't before - only bottles with a more traditional shape. Very happy with it, good purchase.
