i haven't had great luck with them over the years. the journal sizes on the ones i've gotten are always on the big side of the spec, which is not where i want them. fortunately we can take care of that in house but it stinks to have to grind a new crank to make it right. based on my own experience, i won't use one for a combo that'll make significant power, i.e. 900+, i've seen enough broken ones over the years. IMO there are better choices out there. to me, they're a budget friendly entry level crank, for the most part that should work for the "average" street strip crowd.
