- The slow shifting into your two smallest cogs might be due to excess
- friction in the cable system. You can check that by taking off the
- rear wheel while your bike is in a stand, putting the shifter into
- friction mode, and seeing if the movement of the derailleur follows
- the movement of the lever without any hesitation.

- On the other hand, I have the same shifters on my mtb and get flawless
- shifting with a Sedis ATB chain, so give that a try, too.
