MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
I'm looking at replacement shocks on eBay & pinkbike and some have bearings for the lower mount whereas my current shock is fitted with the usual DU bushing + top-hat spacers (20mm width I think) plus a couple more spacers on each side (the bike is a YT Jeffsy from about 2018)
Are these mounting types interchangeable provided the width is correct or do the bearing mount ones only go into certain frame designs?
Define bearing mount?
Trunnion mount shocks, which have a bolt hole either side of the body, will most definitely not fit in place of a conventional eyelet mount shock.
However there are a few different eyelet type bearing mounts, which may or may not fit, so it would probably be best if you could post some links to what you're looking at.
Yeah my Slayer had a bearing mount but was an insert into a 'normal' eyelet with the bearing mounted inside the insert. Things like the Super Deluxe you often see, won't fit non-specific frames.
Yeah not a trunion top mount, just the bottom eyelet has different mountings on different listings such as this example below

yeah.... that's a no.
The rs ones are specific but you can get pressfit bearings (fox among others iirc) which could also be used on an rs shock so it's not a simple answer - when is it ever?
In the case of that shock, no it's not easily swapped.
Ok thanks, I give up with all the different standards. I think the only solution is a new bike!
You need 30mm spacing to run bearing mount, Rockshox now do a kit similar to Fox's version that goes in standard eyelet but aren't compatible with some air shocks.
The actual spacing on mine is 40mm it seems, 20mm for the eyelet bushing/tophat then 10mm metal spacer each side, so do you reckon something like the below would make it fit?
That would work for the shock in your previous but only the bearing end obviously.
I didn't even know they existed, looks like you can buy a bearing mount shock and just pop those adapters on, if your shock bolt is 8mm.
Think to remember is if your shock only rotates a degree or two at one end, you're better off with a bushing than a bearing. I'd say you need to be getting towards 90 degrees before the bearing mounts are helpful.
I used to run a RWC roller bearing in the DHX5.0c on my turner 6 pack, but only on the top bearing.
Looks like those spacers would fit, on a 30mm mount there are just bearing covers each side that must only be about 1 or 2 mm thickÂ
