- gearing 'why hasn't this been done' question
one for the engineers on here, and I’m not one so will apologise in advance if I’m being stupid…
We have hub gears and have had for years and years….but, if you wanted to retail a 27/30sp set up, you needed to have the traditional f&r mechs, chains etc etc.
If you want belt drive, you can get, what, 1×11 speed as your max number of gears?
So, as a thought, would it be possible to have a bottom bracket mounted hub-tupe gearing system? I know that the BB case on bikes would be too small for the stuff needed, but would it be possibel to do?
I’m thinking of a fairly insane 3×11, with an alfine hub on the back, internal 3 speed at the front and a belt drive…would something like this be a possibility? And would there be benefit to internal bb type gearing?

Anyone for 63 gears?…
Front – 16 speed Cambiogear
Rear – Rohloff 14 speeds
Total 16×14 = 224
But if you want to get creative a couple of extra sprockets could be bolted on to the rear Rohloff cog with a derailleur, so
3x16x14 = 672. (It wouldn’t take much work to do).
Yes, I have all those components, but as a dedicated singlespeeder, I am protecting the gearies from their follies by not telling anyone about this idea. Oops!….Posted 6 years ago
