Ok, to be fair I haven't owned Sora. I have rented a bike on several occasions (3 weeks total time) and had to fuss with it quite a bit. Having heard of adjustment issues from others, I assumed it was the group. Could have just needed new cables, though.

Again, have also heard from several people about the thumb buttons being an issue. I mostly didn't like not being able to shift up while in the drops. YMMV, and we all ride differently. I like the drops, and I like to shift quite a bit.

As for my next commuter, for when my stopgap Schwinn is laid to rest, I do hope for DT shifters.
