Alfine 11 IGH on a Quickbeam

IMG_0857, originally uploaded by jimcwarren42.

Jim installed an Alfine 11 internal gear hub on his green Quickbeam. He had a shop spread the rear triangle to 135mm, and he’s running a thumbshifter on Rivendell Bullmoose bars. He says when (and if) a dropbar shifter for this hub becomes available, he’ll switch to drops.

It looks like he’s using Rivendell’s down tube clamp-on cable stops to run the wiring, and then zip-ties on the chainstay.

Cool setup. One could do something similar with the new SimpleOne without too much trouble.

Multi-speed Fixed Quickbeam

From one of my Flickr and RBW group friends. I like his gear spread for a go-anywhere fixed gear bike. He’s using the Surly Dingle double-fixed cog and some larger rings than the stock Rivendell setup.

Rings: 39/45
Cog 1: 17/21 Surly Dingle cog
Cog 2: 23
Gears: 46, 50, 58, 62, 71.5

I’ve migrated toward larger rings on road cranks, too, but I like his 23t flip cog better than a 15t cog. That’s a beautiful spread. He can drop from 72″ to 50″ without taking the wheel out of the dropouts. Flipping the wheel, his biggest and smallest gears have the exact same axle position.

rings 45
50.1″ 57.9″
45.8″ 52.8″

Running the numbers, we can see that he must be using 32mm tires. And, uh, plus we can see them. 38 or 40mm tires will give slightly taller gears.
