maybe :/ I hope not. It's just odd because there is no actual issue with the NDS Side, it stays tightly bolted down with no play once the drive side is tight, but the drive side keeps coming loose.
#3780
Is this a square taper or Octalink crank? Either way, torquing one crank onto the BB shouldn't affect the other. I'm siding with Scrod that you may have damaged the interface by riding it loose and then over torquing. If anything, the NDS is usually the arm that loosens and falls off

DA Octalink bottom brackets are far from "cheep".
Aside from that, why would the BB be causing play in the drive side crank arm?

I'm reading stuff online that says octalink does not deal well with reverse torque - which is happening all the time on a fixed gear if you use your legs to slow down. This could explain why things are coming loose but not why one arm is influencing the other. Also, if the bolts are being tighten with a fairly small wrench, there is no way enough torque is being applied and the cranks will come loose.

btw you weren't joking about how much quieter the EAI chainrings are. put it on and was a combination of adjusting to the GI change and the noise. I kept thinking 'something seems off...' then I realized it was the noise I was missing (but not "missing")

Mavic CXP22's (32h) or Weinmann LP-18's (36h)?

Thanks, Scrod.
@ Itha - both come with Formula sealed. The Mavics are 32h and are $30 more (wheelset) than the 36h Weinmanns. I'm 180lbs. so I figure I'm borderline between 32h and 36h.
