Hi,

I need a triple crankset (or triple crank arms with no rings on) with the following specifications:

JIS square taper;
160-165 mm crank length;
104/64 BCD;
45mm chain line (please, specify which bottom bracket spindle length is required to get that value, if possible);
Q-factor around 160mm

Anything on the market with such features?

Thank you for your help,

crankpaul

I think you would have to go vintage in order to check most of those boxes.

XT cranks are available in 165mm and are 104/64 bcd, but not square taper. They do usually come with a bottom bracket though. Nothing currently available that I know of will be close to a 45mm chainline, more like 50mm.

The FC-M361 & FC-T3010 are triple cranksets, have square taper, 165mm crank length & 104/64 BCD

http://productinfo.shimano.com/#/spec/1.2/TREKKING/Crankset

They both have a chainline of 50mm.
The q-factor on the FC-T3010 is 187.3mm and the FC-M361 is 185.9mm

My Son runs Middleburn 160mm square taper with a 104/64 spider. You will not find these 160mm cranks anywhere other than mtbtandems.com.
He is running a Raceface Ti BB with them.

I'll second the suggestion on Middleburn RS-7 cranks. They are modular with interchangeable spiders, so can install whatever chainring you like.

To get the desired chainline, buy the appropriate size BB spindle and/or get a BB with TWO adjustable cups. I expect a 103mm Phil Wood would be just the ticket.

Recently, another option has popped up for 160mm / 165mm crank. Take a look here under the Thorn cranks. They might work out a little cheaper than Middleburn (but don't have a replaceable spider).
