Except for the DaHon folders which are 1x7, everything in the garage is 120mm OLD and set up 2x5. The Raleigh International has 52-42 up front and 14-16-18-21-24 in the rear. On the Super Courses and, more recently, the Gran Sport I'm a fan of classic "Alpine" gearing 52-40, 14-17-20-24-28 since there are no duplicate (wasted) ratios and with only ten to start with it's nice to be able to use all of them. However, downsides are that double-shifts are almost always required to get the next-nearest ratio and cross-chaining is necessary to use all of the gears. As mentioned recently, cross-chaining a five speed block is tolerable on an bike with long chainstays and a flexible chain but it can be unpleasant and may cause increased wear on a short wheelbase machine.
