Well, that's funny because I still have an old school square taper Sugino crankset that's a 5 bolt 110BCD with a chain guard from guess who -- Bike Friday off my old no longer owned New World Tourist. The five bolt 110BCD pattern is used on old style mountain crank set or touring triple. They might not sell this anymore since it was from the early to mid 90s model bike. 110 BCD was in fast retreat in the past, but thanks to Tyler Hamilton and the TDF which brought back the popularity of 110BCD in a form of a compact double. Plus the Sugino touring triple is 110/74BCD, but you are right as the 130BCD crank is more common than a 110BCD if you want to find a chain guard for it.
