61900 bearings would work. A little narrower than the standard 608 8mm bore. These have the same 22mm outer diameter but with a 10mm bore.
We are trying to target 12mm axle,10 is kinda solved I guess.
I will point out that any 12mm x 22mm bearing is going to have a low load rating. Probably around half that of 608, so they won’t be that robust
I tried this once.
It was expensive, and I was always worried about wearing through them and having to buy more, so I wouldn’t ride the thing. So I’m back to pneumatic and they sit on a shelf.
I would totally ride it if we could get a set for your proposed amount.
cross linking this magic bearing chatter.
12x22mm is a bad idea for what we do. you realize that each ball is gonna be less than 5 mm right?
yeah that’s the rub. the bearing is expensive and you’re likely going to kill it fast and/or unexpectedly.
Yeah and as i said before I’d recommend going an alternative route as the ball bearings are dangerously small
me personally I’d machine down the axles to 10mm…
Do MBS axles unscrew?
I cant answer that but Im assuming youre talking about matrix 2? I do not believe so. MAtrix 2 should be 9.5mm though
Yes, sorry. I get mine tomorrow and was curious.
Weren’t you using ROckstars? those have 27mm seats
Yes but I also have some evolve hubs.
I’ll probably end up using the rockstars for 6” tires as well, just wanted an easy swap lol.
Just use a spacer like trampa?
I did see those, was thinking about it!
Wait but don’t those convert 12mm to 8mm?
whoa.
Those bearings(22/12) are ridiculously expensive, so, I cheated. I took out the mbs axles. Had 10mm axles machined from tool steel. And then i put those in. [IMG_20200806_072031] [IMG_20200807_140106]
yes you are correct. you cannot negative spacer
