I tend to ride long distances (at least 600 km) on most of my bikes.
130 BCD 172.5 mm old Ultegra cranks with 50/38t chainrings on the Frezoni
135 BCD 172.5 mm old Chorus cranks with a 56t chainring on the Moulton fixed wheel
110/74 BCD 170 mm very old Sugino cranks with a half-step + 28t on the Fuji Touring bike where I've never bothered counting the chainring teeth.
110/74 BCD 170 mm modern Sugino cranks with 56/44/32t chainrings on the TSR30.
I'm looking forward to racking up a SR on the tandem and possibly a couple of other interesting bikes.
