Good news that you managed with the lower bearings. Not sure why the difference on the rocker bearings, did you notice the flange on the enduro bearings being thicker at all? Were they like the pic I uploaded?

I bought Enduro max bearings F6902 EA LLU to replace the original bearings, and they're not exactly the same. The flange is slightly thicker on the enduro bearings. The difference means I cannot get the rocker flush with the frame, there's a little gap even with the bearings completely seated.

Anyone had this problem and/or has any suggestions how to deal with it?

Thanks!

Neb, see the picture on this comment, it shows the carbon and the enduro bearings side by side.

What was the model of the Enduro bearing? I have Enduro F6902 max bearings installed in the top link and it seemed to go together fine, the issue I have is that they seem a little tight on the main lower frame pivot, I'd assumed that there might be some debris/paint in the recess so the bearings won't completely fit in.

I have Enduro F6902-LLU-MAX-EA, but there are other variants

I bought the same bearings, and the flange was too thick. It did go in the top link fine, but once I assembled it to the frame there was a gap, so the rocker would move side to side. Have you assembled it back together with the frame, and does it fit tight?

I did not try the lower pivot, but because the flange is thicker I expect it won't go in completely (as you seem to have found).

I managed to strip the head of one of the hex bolts in the lower main pivot. I've managed to drill the bolt out and remove the bearing cover so I should be able to knock the axle out, however it is absolutely stuck....

I suspect there is corrosion between the pivot axle and the inner bearing race.

Any tips on how to remove??

Mine was also quite stuck, but no corrosion. I managed to get it out by turning it (with the hex key) while pushing it out from the other side.

When I sent the initial email I included the two pictures from japjoe7 showing the full kit so they knew what I was requesting.

While it will be nice to have a complete set of extra hardware for this frame I would still like to find another source for the bearings. Prior to finding out about this parts kit I was going to pull the trigger on a full set from 123bearning as they seem to have the correct bearings. I think now I will just order one of each type so I can compare them to the set from Carbonda.

Was thinking of this too, but the F6902 (at least) seems to have the wrong dimensions. The Enduro-branded one should be the same I got (the flange is too thick), and the generic-branded one doesn't seem to have the longer inner race at all.

Good to know we can get the full kits from carbonda.

Is the $60 + shipping the cost for the kit with all bearings plus all hardware has shown above by japjoe7 ?

I bought some 0.3 mm "tunning washers" in a local shop, and using 2 on each side I can reassemble the rocker without any play. They are made of steel though and I expect them to rust quickly, so longer term I would like to get some of those washers bossman suggested (or something else made of stainless steel).

I didn't change the bottom bearings yet but I expect these won't fit, the extra 1.2 mm will be too wide for the chainstay part.

I think for the other bearings I will buy generic ones, they will need more frequent changing but they are also much cheaper and (I hope) will fit correctly.

I'm bummed to hear the bearings are not the same. I was planning to do a bearing swap this winter. Still can't find a high quality replacement for the F6901's. Did you?

How much of a gap are we talking about? .5mm on each side or a full 1mm or more per side? Filling the gap with some sort of spacer may be the best solution. I would be hesitant to modify the carbon.

Me too, I thought people up-thread had used these bearings already without issue, but it seems the F6902 2RS and the F6902 LLU have slightly different flange thickness.

I would say there is about 1-1.5mm gap total (both sides). My current plan is to get some thicker washers (2.5mm) to replace the washers that sit between the rocker and the frame. Unfortunately they are not a standard size, the standard washer with 15mm inner diameter  is 28mm outer diameter, which is too big.

I haven't ordered the F6901 bearings yet, but I did find some online shops in Europe that stocked them.

Thanks for the input, the more I look and compare to other bike geometries, the more I'm convinced XL with ~35mm stem is the way to go for me

If it helps: I'm 184 cm and have the XL with 35mm stem. It fits fine and I think the top tube length in L would be too short for me.

Hey everyone, wanted to re-visit the topic of bearings for this frame. I have been able to identify all the bearings used on this frame. Below are the bearings/quantity

Rocker arm pivot/main chain stay pivot:
F6902-EA - x4. This is a flanged bearing

Seat stay/Chain stay pivots:
F6901 - x8. This is a flanged bearing

Lower shock mount:
6801 - x2

As of right now Enduro carries the f6902-EA and the 6801. Currently they do not carry the F6901. The good news is I have exchanged some emails with Enduro, and it looks like they will be adding the F6901 to the catalog. No ETA but sounds like they will have the standard version and the MAX version.

does anyone know what the maximum dropper post insertion for a XL frame is?

Around 265 mm on my XL frame (OneUp 180mm just about fits showing <5mm seatpost under the collar).

Anyone else having trouble looking at those pics on a monitor?  They are so bloody big I see about 1 tenth of a pic on the screen at a time. (22" monitor)

Same.

Also, just ordered a FM1001 in size XL, and I'm 184 cm

Does anyone know if a DVO Topaz rear shock (165x42.5, TR) would fit in this frame? Thanks!
