MR17287-2RS Size 17x28x7 Extreme ABEC3 Bicycle Bearing, High Speed Non Contact Seals

My bearings blew out on my Hope Fatsno Pro4, and in Hope's literature it says you need (S)17287 bearings. I took a chance and got these as they were the only Prime and cheap option on amazon I could find that had a website for the manufacturer. When I got the bearings (in two days!) I ripped open the plastic bags they came in and inspected the bearings. Take a guess what the rubber seals say... "HOPE 17 28 RS" Exactly what the OEM ones that I took out were. The outer race has the EXTREME manufacturer inscribed in the stainless steel. The bearings feel very smooth and fit into the free hub just fine. I just put them in so can't comment on durability. In my journey of servicing my free hub I've found the root cause of the bearing failing in the first place, which I blame Hope's aluminum freehub for. That's a different story.

I replaced my bearings from my SRAM 900 Rear Hub and for the XD Driver. My OEM bearings started to go bad on my 2016 Banshee Spitfire (for age reference) so I ordered 3 of these to replace 3 of 4 bearings.It works awesome and it smooth. I highly recommend this.
