Bofs 27 speed is indecent..........but its £870 and it will only fit a 135mm frame spacing minimum.What would you need to shift gear on the 2 speed ACS?Quote from: griff on October 29, 2010, 11:42 PMthe sturmey archer gears on both my old choppers bitd were shiteand my mate's grifterSounds like you didn't know how to tune the gearing!!If I decide to gear up then I wont be using a TT central Gear knob either. I've had a few close calls with my knackers too!!!
Those Rohloff hubs are mega heavy.A local MTBer has just spent a million quid (well,a sh*tload) on a custom ti frame/fork/bar setup & put a Rohloff hub on it,thus increasing the weight tenfold!
Unless you've got a seriously steep hill that's impossble to get up.

Moley.....your a mong
hills are no problem to a mole ...... they just tunnel threw.
For fitness you should keep it single speed Unless you've got a seriously steep hill that's impossble to get up. On my ride to work I go from the lowest point in Harrogate to the highest, which is a decent climb. It's only about 4 miles but it really gets your heart rate up as you're out of the saddle for a lot of the way.
Moley - I have an old folding bike with 20" wheels and 3 speed Sturmy Archer (or some kind of copy). I think it the rear wheel would fit a BMX. Anyway, it's yours if you want it (it may be useful on a prototype at least).

Anyway, it's yours if you want it (it may be useful on a prototype at least).Is it fully operational with gear selector, cables etc, etc? Also how is the cable gear selector mounted to the frame? Metal clips or welded mounts or neither?The big point is hub width. It would need to fit into a 110mm frame!! Diggler wont be laughing when he hits a steep incline on MTB and I wizz pass on my 20" Falcon Pro Flyer!! Take that Diggler and stick your negative energy where the sun dont shine!!!
I'll find out.
