The bearings/rollers on a Staton drive are press fit. You have to go to a machinist to remove the bearings from the rollers. The fit and finish of a Staton friction drive is superior to Thatsdax.com's friction drive, but Thatsdax.com friction drive bearings are not press fit. They weren't when I bought mine, which was when he first came out with them.
This is not good news. I was planning to experiment with different rollers on the Stanton
drive but it doesn't seem possible. I guess they want the customer to order a new FD drive
for each diameter. Ridiculous!
