The rear shock on my bike is not trunion. I noticed the noise was coming due to the mounting hardware being 1mm too short allowing the shock to move left and right. I have new hardware coming, but I now need one of those 1mm thick black washers that goes on the outside of the mounting hardware. What are they called and where do I find them? Are they specific to Fox? Thanks

The mounting kit should include everything you need for the specified width.

 

[Electric_City]

it won't. I just need the 1mm Derlin spacers. The shock is offset to one side.

Do you need the dimpled one? I haven't seen one for sale individually before.

But like S4, you could just 3d print it at your library or something...

Sounds like he’s asking for the dimple things.

 

[Electric_City]

These things. There's 3 of them on one side. Two of which don't have the dimples. They measure 1mm thick each.

What funky bike is spaced like that?

You might be stuck buying new bushing kits. Though the 3d printing thing is probably better... Or grab some used one from the garbage at a local shop.

I'm sure @bullcrew has some flinging around..

I've seen those on bikes with narrow shock spacing. Are you sure there isn't supposed to be two either side?

 

[bullcrew]

Had a bike come through spaced out offset to one side a couple months ago ..the head assembly and lower were set over ..

I think I have some of the non dimpled 1mm spacers ..

Definitely mount and look to see if it's centered with off set or if it's off center then they stuffed em on 1 side . Seen that as well .

There should NOT be 3 on one side. Does this bike even have the right spacer kit?

Yes it should. Due to the spacing inside the frame, and due to Fox having the piggyback offset to one side, It's necessary to offset the shock by 2mm. Top and bottom are equally moved over.

What frame is it?

I'm not certain about doing any offset, and by "not certain" I mean "I'm pretty sure that changes things to make it a no go" but I know Trek was running a standard 2eyed shock with upper trunnion mount spacing, so there is definitely hardware for center alignment. We sold some at Cane Creek when I worked there. Might consider looking into that at least and see if there's a way you could get it set up for your needs.

I have seen zero downsides to using normal spacers. Don’t overthink it

That's not me changing anything. Banshee limits themselves to certain shocks based on their frame design. At the bottom of their frames on their website they tell you up front what shocks are not compatible with their frames due to their forged part of their frame. Regarding the Legend-

Legend 27.5 / 29 — Banshee Bikes

www.bansheebikes.com

"MY21 Fox DHX2 shock requires offset spacing hardware to move the shock 2mm to the drive-side for clearance."
"Not compatible with Ohlins TTX22M Side by side version (standard reservoir version is fine)"

Their Spitfire is limited to shocks also-
"Shock Incompatibility: Push HyperCoil springs, DVO Jade X / Topaz 2 and 3, Suntour TriAir2 and FAST Fenix are not compatible with this frame model. The Manitou Mara Pro requires the short reservoir option, and side knob climb switch"

Fwiw, my Devinci Wilsons shock was not on center either. I don't think it's as uncommon as people think. I just don't think the companies talk about it as much and/or - like Devinci- have the frame made with the offset already in it so spacers aren't needed. Trek had a Fuel with a Fox/Penske shock with a trunnion up top and a "Y" thing down bottom. The bottom was off center by a very significant amount.

In my case, either the wrong mounting hardware was used. Or the frame spacing was machined wrong. Either way, a 1mm spacer will resolve this issue.

I'm not. A 1mm spacer is all I need!

Or a 3mm.

 

[Electric_City]

Fwiw, this is why the shock is offset to the drive side by 2mm.
