First and foremost I apologize if some of the info provided is no the most accurate, as I am a bit of a noob when it comes to mountain bikes and it’s technicalities.
So as per the question:
I had recently had to make a warranty claim on my orbea oiz, I had a 2020 mode as per my understanding with both forks and shock of 100mm travel.
The only option I had was to get a new 2025 frame, which in theory sounds great. Problem is the new frames all come with 120 geometry.
So I know already I’ll have to buy new forks to accommodate this change.
Regarding the shock, the new frame requires a 190*45 configuration.
This is where my doubts begin, was being told by someone that the travel of a shock is determined by the frame itself and the mount configuration.
Is this correct?
Also I’ve been looking around to buy the parts I need and was told by a seller that a shock can be adjusted in multiple configurations when I specifically asked for a 19045 shock.
I was told it could be changed from 19035 to 40 or to 45 in this particular case.
Is this also the case?
So can I determine somehow if the shock I already have could be adjusted?
That is of course if the two aforementioned points are to be true.
Apologies once again for all the confusion and perhaps not enough info provided.
As I said I am fairly new to this and am trying to educate myself figure out things as I go.
But now I’ve just been bombard with all this info that I don’t know if it is accurate and am trying to wrap my head around it.
I’ll post a photo of my old bike, unfortunately I don’t have a close up of the rear shock to be able to provide a good photo so all I have is a print from a video.
Thanks in advance for all the help and patience.
If there is any further info I should provide please let me know.

Is Orbea not including a shock? Full suspension mountain bike frames typically come with them.
There’s not really a single answer to your question. The rear wheel travel could have been changed without changing the shock. They could have done something very different. They could have spec’d a shock with 20% more travel.
One thing I’m confident about: you don’t have a 100 mm travel shock.
Regarding the seller’s claims, get the service manual for the shock. Usually you can download them from the manufacturers’ websites. If you’re not prepared to do the work yourself, getting a shock set up wrong for your application is probably a false economy.
To clarify, Orbea sent you a new frame but it’s got 120mm of rear travel compared to your old bike which was only 100mm? Did Orbea not send you a shock with the new frame? Do you still have your old shock?
Assuming you are sitting there with a few frame and the old shock. Yes shocks can sometimes be changed in terms of eye-to-eye length (the total length of the shock based on the distance between the centers of both mounting bolts) and stroke (for much the shock can compress). You would need to check with Fox or your local dealer if your 100mm shock could be adapted to your new 120mm frame.
Alternately just buy a new shock with the correct dimensions. Buying a shock is expensive and kind of a hassle – if you go this route get the correct size right off the bat. There are lots of shocks out there to buy. Don’t let a seller tell you it’s easy to send the shock somewhere to get the travel adjusted (this just adds cost and risk).
I would buy a brand new shock. Consider yourself lucky that you just got a new updated frame for free. And now buying this shock is the cost of doing business. If you buy a shock from the shop that handled your warranty they will make sure you get the ideal shock/fit, the correct mounting hardware and be a useful resource in getting the shock running optimally and you’ll strengthen your relationship with them. AND you’ll get a full warranty on that shock. In the long run this is a better option.
