Rode fine with these for 3 years (Ultegra and DA chains), then in the last 2 months, two of them broke. Both times I was going uphill, the last time it was when I shifted under torque, though the first time I was not shifting.
1. If this pretty common?
2. Bought a couple KMC Missing Links to try out. Anyone have comparisons between the Missing Link and the Connex?
3. I also bought a couple KMC 10 speed chains (Nashbar had them on sale) that I plan to use soon. Have not found anything telling me whether I can reuse the pins on those or how I can shorten/connect the chain other than by using a Missing Link. Can I use the Shimano 10 speed pins on the KMC chain?
