Double the price, double the performance? Please advise.
I have a set of the normal Cubus and I wouldn't pay up for the Flexus version. At that money I would go FMB/Dugast. The regular Cubus weighs the same as a Grifo so they are reasonably light. The nice thing about th Tufo's is that they are bomb/flat proof so you can run them at low, low pressure without fear of flatting.
