This is very common for truvative cranks. If you did the locktite properly(clean off grease before applying, let it sit for a minimum of 24 hours...)And it still comes loose then pretty much the only thing you can do is carry around an allen key when you ride to tighten it every once and a while. I have the same problem and that's what I do.

I have the same problem with my crank, and carry an allen set wherever I go. Haven't got to the point of buying new cranks yet.

go to the hardware store and get some jb weld kwik set it's strong enough to hold the cranks whale riding and you can still remove the cranks wen it's time to get them off put on the splines NOT THREADS or bolts

Just to clarify, is your bashguard that is coming lose or the actual cranks?
If is the acutal cranks (the bolt that goes into the bottombracket) try cleaning the bolt and wrapping it with Teflon (plumbers tape, the white stuff). This solved the problem of my Truvativ cranks coming lose. (Never had a problem with Race Facetup )

How are you tightening your bashguard on? I have seen people try to tighten them without holding the back of the bolt with a large slotted srewdriver, only using friction, only to have the bolt come loose withing a short time.

its not the bashguard, its the bashguard side arm. left side stays on but right is being a bitch. ill try the plumber tape though. thanks!

I'm having the same problem as everyone else here. The Truvative crank on both of my bikes keeps falling off so i carry around an 8mm all the time... I'm never buying this kind again. Saint or raceface all the way.

it happened to my 07 hussefelts and it got loose all the time, and one day it just fell off, turns out the thread of the bolt was stripped so i replaced the bolt and its fine now
