I'm considering a Grubee HD Axle Kit and would like some opinions...

Sturmey Drum

i have the x-fdd dyno hub, and have been very happy with it. it provides plenty of stopping power, and my back brake is just the coaster brake that came on the bike. i have ridden it over mt. soledad twice ( i estimate ~15% grade), and didn't have any overheating issues on the way down. i tried to keep the speed up to avoid being overtaken by cars on the way down, but did use the brake a fair amount. overall, i am extremely happy with the product, and i am usually very picky.

I like this idea overall, but how is hill climbing? Isn't there some extra drag from the hub dynamo. I'm aware that you can get a hub without a dynamo, but all the bullet lights and stuff you can get is so neat.

i'm not actually using the dynamo to power anything at this point, and any drag seems negligible. i run a 48 tooth sprocket, so it climbs hills pretty well.
