## Product's reviews:
- Masterdrive qd hubs - USED THESE FOR YEARS WITH ZERO PROBLEMS! THEIR PRICE HELPS & QUALITY SEEMS EXCELLENT! VERY GOOD VALUE!
- Masterdrive f 1 3/4" inner qd hub - Used maybe a dozen of these, zero problems. Why pay 50% more for a name brand when these work great?
- Masterdrive purchase - service and shipment was great
- Quality product - Heavy duty. Not likely to bend or warp
