A Close Look at Speedmaster's Roller Rockers
The ad says needle bearings but you got bronze bushed ones? Interesting. There's just one way to find out if they are any good. Be sure to check them at 500 to 1000 miles to see if something is giving out. Our cheap eBay PRW's with needle bearings wore into the shaft in less than 1000 miles; the shafts look to have not been hardened properly.
