Hayes had somewhat of a renaissance thanks to its powerful four-pot Dominion enduro and downhill brake, taking it to the next level Hayes then modified and upgraded this platform to create its best MTB brake to date, the Dominion T4.
The aim when developing the Dominion T4 was to reduce weight without sacrificing performance. Despite looking relatively unchanged, the Dominion T4 has had an almost complete overhaul which is claimed to have saved 100g a set over the standard Dominion A4, bringing the weight to around 280g at each end.
