I don't know but part of your issue might be that Truvativ doesn't make that short a crank in that model.

Do you have to stay Truvativ? Likely you can change to most any other popular crankset. I think the shell for your BB is going to fit many threaded BB like what they use for Shimano's hollowtech II cranks and many other brands.

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

To help you, relavent information would be:
-Gearing of the crankset (what tooth counts on the chainrings, and how many of them)
-Bottom bracket shell of the bike--GXP can fit on a bunch of (almost all?) bottom bracket shells.

You don't need to keep with Truvativ and you don't need to keep with GXP--in fact, I'd generally recommend against both.

It's relatively easy to find square taper cranks with short arms designed around 110BCD for road double setups. It's harder to find either higher performance cranks or triples of really any kind. Most brands only go down to 165mm in most models, which I agree is unfortunate.

You can check that length here, The Recumbent Bicycle and Human Powered Vehicle Information Center,
but in practice most folks can handle a range of crank lengths. You can find shorter cranks, but most are in the 165 to 175mm range. And I once sold a bike with a 175mm crank arm to Jim Chones, the 6'11 NBA player. And even very short riders often use a 165, and Truvative offers some cranks in that length. Have you tried a 165?

Why do you need to replace the crank? Triples are really hard to find and so are very short cranks. Maybe https://hostelshoppe.com/products/or...caAhStEALw_wcB with some specialties ta chainrings. Bike dealers with jbi accounts can offer them also. Or there are a number of 150mm square taper cranks you could set up with a tripleizer ring.
