Schlumpf being way expensive, and Hammerschmidt needing ISCG mounting tabs at the BB, anyone ever use or think about installing one of these?:



This is the 2sp Metropolis to which I referred previously, 1:1 and 1:1.6 ratios -- 28T chainring standard; equivalent of 45t chainring in overdrive. I'm seeing it online for $299.00 retail, as low as $225 ebay.

Unlike auto or back-pedal shifting, this does complicate matters a bit with handlebar mounted shifter and cable/housing setup.

Most folders have narrower than normal front hubs,but in the rear it depends on the frame's rear spacing. Most 8+ speed hubs require 135mm,but Sturmey-Archer makes a narrow one specifically for folders/small wheel bikes.

hmm I just assumed that the mu uno had 7 or 8 speed spacing. but diameter isn't an issue? i.e. 20" wheels also have correspondingly smaller diameter hubs.

Just the angle of the spokes when building the wheel. Properly done it's not an issue. My old FlyBy had a Nexus 8 and the frame looked similar to the Mu's. There are plenty of EOM and custom folders running IGH's.

Measure the space between the rear dropouts to see what will fit,and just make sure the wheel is built right.
