So what is the lightest, practical build you can do using IHG (>3 speed), dynamo lighting, rack and fenders.

ie put a butted aluminium frame, carbon fork, Shimano Alfine rear and dynohub together with some lightweight but strong finishing kit (ie no weight weenie fragile bits). Is this basically a Civia Briant or does that use heavier than neccessary components?
Is there a useful frame out there that we could use?


My ride is on the heavier side because it has some frame hinges and a fat slab of metal at the eccentric bottom bracket. I don't find the weight to be an issue.
