I bought this bar for my gravel bike so I could have more control on single track. It did offer more control going downhill on dirt however I didnt like riding on the road in the drops. Also the drop didnt get me any lower for aerodynamics . I also didnt like the ergonomic future of the bar because it forced you to put your hand in one place . I ended up getting a salsa cowbell instead . I like the cowbell on the road more than the Ritchey. Both offered greater stability going downhill on the dirt, but the salsa seems like a better cross between road and gravel .
I purchased this chain as a spare to sit on the shelf for the original on my CX bike. That chain has almost 3000 miles of Nebraska gravel, CX, and MTB singletrack and is in great shape with little wear so far. Like I said, tougher than nails. Paired with the SRAM X-Sync it makes a near bombproof system. Of course, I keep it cleaned and lubed well, but, man, it's a tough chain.
I've been using my Vector 3 pedals for about a month. The training data is awesome and helps me hone in on my weaknesses.
After my first ride in wet conditions, the right pedal dropped out, it's easy to pull the battery and slightly pull the inside contact up so it makes a better connection. Power is the best way to train and track your performance improvement. Conditions and equipment can vary so much so power just makes more sense.
The ease of installation and ability to move pedals between bikes is very convenient.
