I am of the opinion that you are right, but, my opinion that you could tie two horses to each end of the rear triangle and have them pull, the schwinn would come out on top. I am not talking about old masi's colnago's but schwinn varsity's. If you have all the time in the world i say do it your way. If you need to get a messenger back on the road immediately after he pretzeled his wheel, i me myself have with great reward spread a frame open by pulling it apart in a reverse way, similar to a reverse bench pec dec exercise. Thats all, it worked for me, and i never had a complaint that i remember.
