I purchased two sets of bearing for my vintage Russian Motorcycle before Christmas. I didn't actually know the size I needed, so I took an old Russian parts catalogue over to Simply Bearing in Leigh, and after taking a quick look at the bearing size shown to the old booklet, the guy behind the counter was able to give me the exact same ones shown in the 1967 booklet. I was going to buy these bearing off ebay, but because S/Bearings was located only 6 miles from my home address, I decided to give them a try. I found the staff very helpful, and I will using there services again - Definitely.
