Head's still a bit foggy this morning, so bear with me if I sound ridiculous (this'll be a bit of a 'stream of consciousness' post!)… Couldn't sleep that well last night and found myself musing over my ideal gear setup (as you do at 3am 😆 ).
Now, I really like my alfine, I like not having a dérailleur to wreck and love the 'winter proofness' of it, but I do find it a bit heavy at times, and in all honesty I find the gearing a little wasteful/inefficient (I think that'd be the term?) What I mean is that I don't really use all the gears, it's either in the 'hardest' gear for speed, in the middle for cruising, or in the 'easiest' for climbing/winching/spinning up hills.
I also really like my SS, nice and light and simple; and 32/16 is a good usable ratio generally, though obviously (sometimes) tough to climb with, and it spins out quite quickly as well…
So I got to thinking… would I be happy with a combination of the two? A superlight 3-speed ISO disc hub? No idea on the ratios, but personally, I'd want a nice 'speed' gear (say spin out around 80rpm at 30km/hr or so), a nice 'middle gear' (say spin out around 80rpm at 20km/hr or so) and a good 'climbing' gear (akin to a 36 single front and a couple of gears up from the granny on normal 9-speed cassette; as I hardly ever find myself at the very biggest rear cog, unless it's stupidly steep!)
As for the superlight bit, what could you make it out of? Carbon? Titanium? Aluminium? Exotic plastics? What about the internals? Would they have to be steel for durability, or are there lighter options available?
Also, would it be possible to build it with 'instant engagement' like a King hub?? That'd be uesful, wouldn't it?
And… could all this be done for a similar price to a King rear hub, say around £300 or so do you think? Or am I wishing for the moon on a stick? 😆 😳
Would be interested to hear any thoughts and suggestions 8)
