My rear left advance roller rack wheel failed the other day 😱 and it shocked me because I really don't roll the bike folded much, and I installed the rack barely three months ago. (By comparison the Easy Wheels on hubby's Brompton are going strong after a year+)
The replacement pair of advance roller wheels I paid $28 for less than 12 months ago now retail for $65.99 on the Brompton site so I am very interested in figuring out how to rehab rather than replace wheels that fail going forward.
Unfortunately, I don't have a 3D Printer nor do I live in the UK (for those that meet either condition, Velocity Printworks has your 3D needs covered👍) so I'm trying o-rings available on Amazon.
I ordered 55mm OD, 45mm ID and 60mm OD, 50mm ID. Getting the 50mm ID onto the advance roller wheel required stretching so I didn't bother opening the package of 55/45.
My opinion is that a 60/50 o-ring is better than nothing but it's not an ideal replacement as it sits too deeply in the channel. (See the second photo.) I've ordered 62mm OD, 50mm ID 🤞 which should arrive the first week of August.
For anyone thinking they can do without a bumper on the wheel, think twice. The damage you see in the last photo was caused by the short trip from my car to my front door.
