My work is running the bike to work scheme thing, and this year I'm hoping to take adavantage of it. I've narrowed my choice down to two bikes: The Kona has an aluminium frame and steel fork, 700C wheels, hydraulic disc brakes and derailleur gears while the Charge has a steel frame and fork, 700C wheels, hydraulic disc brakes and Shimano Alfine hub gear transmission The chain tension is acheived via an eccentric bottom bracket arrangement. I shall be using the bike for shortish journeys (10-20 miles) to start off with but might want to go further in the future. Both bikes have all the fittings I want, take mudgaurds and cost the same (£700). I want disc brakes because I'm feed up of wearing rims down in winter. Questions are; Has anybody got any experience of either of these bikes or the Shimano Alfine transmission? Which one would you go for and why? And how seize-proof are EBB? Thanks in advance.
