^^ha- That is some of the finest English made bike products ever. No thanks to taking one apart! Oh thanks for mentioning seals. Damn thing weeps like a typical old English car or motorbike! But, I've learned to store it with the hub oil port upward and lean the bike slightly opposite the drive side. Overall though, quite well made. The Styria is made in Austria and is a copy of the SA. I've been told parts do interchange. Curious what trade relations the UK company had with these Austrian's or patent arrangements (post WW2).

^Haven't charted the g.i,. but I assure, no 1/2 step. Also, would be hectic to master the levers and combo of gearing as it is now ...LOL Typically and just before an ascent I drop the hub into low. For an IGH, you can only shift when NOT pedaling. For the derailleurs its the usual shift WHILE pedaling. The front bailout works quick and slick. Has no cables with just a direct lever.

Anyhow, could play with the following:
according the IGH booklet, L is 25% lower then N (assume 1:1) and H is 30% higher.

The three cogset is 15 - 20 - 25T

Chainrings are 46 and 52T

Not so sure with the above would meet your low but should achieve it on the high. Curious how drastic it would be in comparison with a 20-24-28 cogset.

misc.- crank length 165mm. Todays bikes are going short like this but I still prefer the 170 or 172.5
