I have found a 16 tooth difference between rings unsatisfactory on two counts. First, when I shift between rings, the next gear I am looking for is somewhere at the other end of the cluster, and the wider the range of the cluster the more difficult it is to find that gear. A lot of momentum is lost on hills while I search for it. Second, front detailers will shift 16 teeth, but they don't really like it and tend to do it slowly. More momentum loss. I have found better ways to get a wider range double without these problems. First option is a 48/34, which will shift much faster and put the next gear exactly two cogs away. The 12/48 is plenty big enough for everything short of hi end field sprints. Better yet is a 44/30 with an 11-28 cluster. the 44/11 is the same as a 48/12 and the 30/28 is only a half gear higher that 34/34. This combination offers a cleaner shifting pattern and more closely spaced gears. I also find I actually have less need to shift the front at all, although my Campy derailler does it so effortlessly that I never hesitate. I have also found that this combination works very well with the new Shimano RD short cage, which greatly improves friction shifting. I am using the White VCB crank on my Ram and really like it, but you can also get a 44/30 with a number of cranks that offer 94 spiders - DaVinci sells one (made by White Ind) and of course the beautiful, but expensive TA Carmina. I wish RBW offered a good, sensible compact double. (hint, hint)
