I had this with a Hope Bulb from way back, ate bearings every few weeks and the rear hub developed a lot of play. The final straw came when the axle broke apart and killed the ratchet, so Hope sent me a ProII Evo at minimal cost and it’s been absolutely fine since.
This isn’t the first report of excessive play I’ve heard about Hope hubs, but it’s not massively common – sending them back to Hope should resolve it.
I’ve three sets of Hope hubs in all and aside from the wonky Bulb they’ve all been fine. To put that into perspective, I’ve a Ringle Jumping Flea hub that killed it’s bearings after about six rides and a Formula hub died on me after six short months.
