Hi folks, looking for some commentary on hub/gear combos suitable for a 4 stroke Huasheng application. Current build is direct drive, using the Sportsman sprocket adapter with a 56t sprocket on a KT histop coaster hub (GT2A-S frame). It starts from a stop great and climbs hills wonderfully, I've got some big ones I need to get up and I weight about 205lbs so I'm not a lightweight. I would like to add some gears to the mix to bring the RPMs down while cruising. I'm limiting out right now at about 27mph @ 7800 RPM. Ideally I'd like to be able to cruise at the lower 6800 RPM where the max HP design of the HS142F is. I don't want to lose the low end, but I would like to be able to up the gearing a little while cruising a stretch of flats that makes up about 50% of my commute. I've been looking at 3speeds and deraileurs, and I would favor a 3 speed for simplicity and the ability to use a heavier chain, unless someone can tell me it's really OK to rack up miles spinning a derailleur with a 4stroke. Longevity is the obvious problem, are the nexus 3speeds up to the task or are sturmey archers the only way to go? Of the sturmey archers are the freewheeling models (like the SRF3) OK or is the S3X the only one worth considering? I realize I could just stick a freewheel on the S3X, just looking for as much info as I can get before making any decisions. Thanks!
