I apologise ahead of time for yet ANOTHER single speed chainline/crank compatibility question.
The specs for this crankset are (according to the current Driveline website):
- Length - 170mm
- BCD - 130mm
- Chainline - 45mm
- BB Axle - Square (103)
I have measured my bike, and it has the following relevant dimensions:
- 135mm rear hub spacing
- 45mm chainline (measured from centre of seat tube to centre of chainring tooth)
- 68mm bottom bracket housing width
- 110mm bottom bracket spindle length
This doesn't make sense to me because the Driveline website gives a 45mm chainline on a 103mm spindle, but I have a 45mm chainline on a 110mm spindle. Have I misunderstood/miscalculated something?
Maybe the P1 designation on the Driveline website indicates that the current model is different from the 2013 version used on my bike?
