Has anyone used a SRAM Dual drive? or Shimano Nexave IF-C530 which I think is an equivalent? – 3 speed hub gear with 9 speed cassette.

I'm eying up a small wheel Tandem Circe Helios as a family taxi/school runner, – which will easily fit either my 7 year old daughter, Mrs MC, or even me on the stoker. (Yes it does, we tried a demo one).

I need a big gear range though, which just can't be got with only 2 front rings on stock bikes.(Third ring is used for transfer). – Hence looking at Dual Drive which seems to do the job.

Anybody used one? I can't find much about them, and much less regarding Tandems (Yes SRAM bumf says not suitable for tandems, – I have seen that!).

hi, i am currently running 120 gears using a sachs 3×7 dual drive hub fitted with a 10 speed cassette with mods and a modded deore chainset with 4 cogs and have had trouble free cycling for over 2 years now, on my atb, if you would like more info with gearing "kellyalexander2009@hotmail.co.uk" i am currently working on a nexave intego which i hope to get 132 gears, but have not tried this yet, hope this helps AL
