Options for rear cross-over cranks for C'dale 2007 road tandem
Hi
I've just bough a 2007 Cannondale road tandem. This comes with 175mm and 170mm cranks. I am looking to replace the 170s on the back with at least 175mm which I assumed would be straight forward since the front cranks are 175 mm. I though I'd just by a left hand front and match it with a standard 175 right hand tripple. Easy!! But no, none of the tandem shops I've contacted have can provide a rear set of the Truvativ Elita Tandem cranks. So I contacted the importer into the UK who told me that Truvativ don't supply or even make these cranks any more and they couldn't get them. When I pointed out that the 2009 C'dale road tandems ships with these cranks they did come back to me and said that Truvativ don't supply these cranks seperately, only to specific manufactoruers to order. They said the only way I would get a pair would be to contact a C'dale dealer as they are obliged to carry spares. Where they would get them from I've no idea. But anyway, I'm struggling to find anyone anywhere to get a pair of rear 175mm Truvativ Elita Tandem cranks for a tripple ring to replace the 170mm.
If anyone knows of anywhere where I might be able to find a pair that would be great.
Failing that, I believe these cranks use the ISIS crank arm fixing so if anyone has any other alternative cranks that are compatible with this fixing that would also be appreciated.
I'd prefer not to have to replace the entire BB to sort this out but if that's the only way, any more dramatic suggestions would also be welcome.
Thanks in advance.
Cheers

ISIS is not used much anymore. TandemsEast claims to have Calfee 175 cranks on their web which I think are ISIS, but they are expensive and I don't know they would sell just the rear cranks.
Other than ISIS your 175mm options would be FSA Gossamer or DaVinci.

This probably won't match, but you can get a 175mm Truvativ left-side tandem crank from this eBay seller:

Also, this person has a NOS Specialized tandem crankset in 175mm (but you will need square taper BBs):
