My LBS said they have already received a new bolt for mine. I'll keep my fingers crossed that it is a useful one.It's good that hopefully an updated bolt from Orbea will address the problem for everybody now. It really ought to be a free fix given to all owners.

That is very neat! I only knew the ones that look like split tubing. Will this work though? Maybe I am wrong, but in my memory the bearing spacer is completely flush with the inner races and only has two slits where the side faces are exposed.You can get bearing pullers that remove the bearings without having to hammer them out. This link is to an expensive version but you can get much cheaper kits that do the same.

That main pivot spacer is very close to flush with the bearing inner race. It might be necessary to hammer one bearing out, remove the spacer, and then the other bearing could be pullded out.
Something I just noticed from a quick Google search is this company selling pivot bearing puller kits for specific Orbea bikes, including the 2020 Orbea Oiz (not sure exactly what is included in the Oiz kit):
Bearing Puller Kit for Orbea Bikes
Bearing puller tool kit for Orbea MTB frame pivots - Rallon, Occam, etc. Each kit is tailor made with all of the tool sizes required to remove the bearings from the selected Orbea frame (one, two, three or four tools depending on the frame). Fast and free shipping in the UK, low cost...
www.bearingprotools.com
With my bike the warranty replacement bolt from Orbea came with a new set of Enduro Max bearings and spacer so the bike shop pressed the fresh bearings into the frame as part of the warranty fix. If you get the same it would probably be most straightforwards to have your bike shop fit the new bearings for you so that it's done as part of the warranty process.

The main pivot bolt and bearing wear issue seems to be with the 2019 / 2020 Orbea Oiz OMR carbon frames.
Regarding the 2021 Orbea Oiz it looks like Orbea do have a new bolt in production now (see Rasmazzer's picture in Post #1,354) so it will hopefully be a running change made on any later bikes. I don't think there are many actual 2021 Orbea Oiz customer bikes out there in circulation yet so bikes getting delivered in future should have the new bolt as standard.
Edit: Just to add according to the manuals on the Orbea site the 2021 Orbea Oiz OMX carbon frames appear to use the same parts for their main pivot assembly as the 2020 Orbea Oiz OMR frames, including the same pivot bolt. The Orbea Oiz OMX has a redesigned swingarm however so the spacing could potentially be different. Existing 2021 bikes probably need checking just to be on the safe side. I haven't seen one to know for sure either way.

I picked up the new bolt at my LBS. It is the same as the old bolt, i.e. 15 mm thread length. I talked briefly with owner when he gave me the bolt. He claimed that Orbea thinks problems with the main bolt occur when the suspension is not properly set up so that there are too many bottom outs. He further said that this is why he always asks for weight when he sets up the bike for his customers. Yes, really impressive, wow... At this point, I had to choose between getting angry about the complete disregard for the engineering fail and getting on with my ride. Considering the apparent total lack of understanding of the problem with the incorrect thread length, I left to ride on. It's a nice sunny and warm day after all.

Should be easy with a routing tool like Park Tool IR-1.2
I have a 21 Oiz M10 and I need to get a shorter stem. I was going to use something I had on hand, but upon looking at the spacers and headset cover It appears to be a whole system where I can’t use normal round spacers and a normal 31.8 stem. Can anyone help me out on what I need to replace in order to use round spacers and a normal stem? Thanks!

From the pictures it looks like for a 2021 Orbea Oiz you should be able to take the integrated stem off and put a normal round steerer stem straight on. The shaped spacers are flat on top so the contact area between the stem and the spacer will be the same as if you had round spacers.
You could probably pull all the teardrop spacers off and use round spacers with the existing dust cover too. The aheadset top cap would need changing to a round one and you'd use round spacers above the stem with a standard round stem
For a full switch to a standard headset you will need a new round dust cover, round aheadset top cap and round spacers. The actual headset bearings wouldn't need changing. You could get a Cane Creek 40 Series IS42/28.6 low stack upper assembly for example. That will go straight on turning the headset into a standard round one.

I picked up my new bolt set yesterday. Also 15mm thread length ? I am riding with my old bolt in the frame again after replacing the bearings. I feels fine at the moment (after 500km) so I will let it in and replace it when the bearings need to be replaced again.I picked up the new bolt at my LBS.

Hi there!
You mentioned you have 4 piston M8120 brakes on your Oiz. How did you fit rear caliper into the frame? I had same idea to upgrade to 4 piston brakes. I have asked Orbea by email if it is possible to install them and they responded it is possible. So I have ordered M8120 brakes to find out there isn't enough space for rear caliper in the frame. I would need to sand 2mm from frame and the caliper would still be touching seatstay. So I just upgraded to SLX 2 piston caliper as original one was fading easily. I don't need to mentioned I was pissed off.

Btw. I have same main pivot bolt problem. I have already put a claim through my LBS. My concern they will send me just new same bolt seems to be accurate

On my frame the Shimano Deore XT M8120 4 piston rear brake caliper with a DT Swiss XRC1200 rear wheel would just about line up without modification. The caliper was touching the frame but the wheel would turn without the brake rubbing.Hi there!

I wanted to have a bit more adjustment available though, and didn't want the brake caliper touching the frame, so what I did later on was to use a metal file and file down the outside edge of the Shimano Deore XT M8120 4 piston rear brake caliper by a few mm so there was more of a gap. I was careful not to overdo it but that works ok without affecting the brake function.
It's really just that sharp point on the outside edge of the brake caliper that touches and the metal of the brake caliper is very soft so it's easy to file down.

The simple answer to this is that the riding you should be doing on the Oiz really shouldn't need a 4 piston caliper.Hi there!

It's a poor design by Orbea, but running a 180mm rotor on a 2 piston rear caliper, and a 180mm on a 4 piston on the front is more than enough stopping power.

IMO 4 piston caliper is in general more responsive and allows more precise brake application. Stopping power is not limitation here however with precision comes bigger margin and faster descends.

Hi.
I'm eyeing out a oiz m-pro TR for 2022 and thought I would ask fellow riders what you think of the bike (120/120mm susp.) in the trail discipline?
I get that you can't use it in Enduro stuff but how does it handle normal trails that are red, features like tabletops, drops, jumps, and such?
Also, what are the maximum width tires that you can fit rear and front?

Damn it... I was really hoping you would say otherwise.
For me it handles ok for normal trail riding. I ride jumps, gaps, drops, tabletops with it. I like that it still is a fast bike but with the ability to handle more technical terrain for an XC bike.
I do like to climb technical stuff and be fast on singletracks. So for me it’s a good allround bike.
