Does it match the frame or the fork?
Is that like matching collars and cuffs?
When putting a new tyre on a nexus-hub-brake wheel, make sure the hub brake fixing nut doesn't come loose, causing the brake to completely mis-align and then seize "on" a mile or two later. Shimano instructions say "don't dismantle this component", but they don't say what to do if it dismantles itself.
When re-assembling a nexus-hub-brake, grease with roller-brake-grease, not common-or-garden teflon grease. Or plan your emergency stops 100 yards in advance. Then buy a new one.
Don't rely on VAR tyre levers to get a tyre off the rim without putting the bead down into the well opposite where you're making the first attempt to lever the tyre off. Remember to retrieve the snapped bits of tyre lever from the well of the rim.
