Yer checking out the site that hub looks HEAVY and its only a freewheel hub not a casset hub. Another point you can only get a 13th freewheel on meaning you can't run the gearing 90% of mod riders run 18:12. I say it looks pretti crap for trials, strong, but its not what i can see anyone in the trials world running. Weights: Homer = 512g + freewheel Profile = 317g T master = 240g So basicly twice the weight of a T-master.
