Replacement for Truvativ Elita Crankset ISIS Splined
Hope the NSA doesn't red flag me for posting ISIS...
But I have an old Truvativ Elita ISIS 172.5 double road crankset. It's the GXP style where the right side has the thru axle attached to the crank arm and spider, and the left arm bolts on to the spindle. As these are notorious for, the left crank arm comes loose on me now after about an hour of riding, regardless of how tight I crank that sucker down using an 8 mm pedal wrench. I need to replace the crankset, and I was wondering if there's something specific I should look for when it comes to matching the crankset to the BB. I have an older aluminum frame (2005) that has the 68mm english threads, outer bearing BB. I was hoping I wouldn't have to replace it, as it seems to be in great shape.
Thoughts? TIA.

Your current crank isn't ISIS. ISIS bottom brackets were splined spindle designs that both crank arms bolted to rather like a Shimano Octalink. You might consider one of the Shimano Hollowtech II cranks and bottom brackets. They also use external bearing cups and have the nspindle as part of the driveside crank arm but the non-drive side arm is clamped very securely.
