When spinning on road, not so much.


One con of triples is that at least for me, a dropped chain off the small ring seems far more likely. Chain tension drops a lot more going to a 22, 24 or even 30 ring than to a 34 or 39 small ring.
Not really. With a 34T chainring, a 5-tooth jump from 35 to 40 is 14% and a 2-tooth jump from 11 to 13 is 18%. If the steps are too small, you end up shifting constantly, and if too large, you may not have the ideal gear at times. Rohloff Speedhub 14 has a 13.6% step between gears across the entire range, and is regarded as "perfect" by many.
