"28 inch wheels" That means... 700C x ??mm tires ? ISO 630mm? ISO 635mm?
How many teeth does the sprocket have? No mention of it anywhere...
I believe the 5 speed hub is the
X-RD5(W), with drum break. The gearing ratio is 256%.
• Gear 1 - 62.5% (-)37.5%
• Gear 2 - 75% (-)25% (Gear 1 + 20%)
• Gear 3 - 100% Direct Drive (Gear 2 + 33%)
• Gear 4 - 133.3% (+)33.3% (Gear 3 + 33%)
• Gear 5 - 160% (+)60% (Gear 4 + 20%)
On the Sovereign models the front hub is the
X-FDD with 2.4w dynamo (no powering a back light), and on the Classic it's the
X-FD.
The Sovereign's front lamp is the
Busch and Muller Lumotec Retro,
without standlight. I think the rear Pannier light is currently the
Busch and Muller Toplight Flat.
That's all I know.
No idea about the sprockets.
