I would keep it about there at 2600 for now. How much have you lost at 2900, probably a bit, but it won`t allow you to continue unless you either A. increase your muscle mass thus increasing your caloric needs, B. increasing activity or C. you are already lean and now are adding back calories.
It also depends on when you want to be in shape. If you are in no hurry, you could ride 2900 for a few months, then just decrease calories only 50-100 in a few months. Most people don`t realize that is all you need in order to facilitate weight loss again. Most are way too drastic and it does not have to be at all.
