Rockshox - Reba upgrade from 100mm to 120mm

[@CHADOYCMTB]

hi i just want to ask if all rockshox reba from 2019 to 2021 model.100mm are all the same air dumber??thanks.

[@jamisgarmont]

Hi! thanks for the video. I did this upgrade and fork is working great, except - on rebound the fork fully extends and Tops out/ clicks. Reminds me of a loose headset back in the day. Action is good on compression and rebound, but if Iean back and lift then it tops out. Any experience with this and a solution? I found one thread suggestion that maybe i misaligned an O ring...? But no neg. pressure issue. Maybe first trouble shoot is to add oil to motion control rebound damper?

[@marcinhryniszak]

Hello. I didn't have this problem with my setup. For sure I was checking the oil level so maybe this can help.

[@kyzersoze9002]

What would I need to do to change from 120mm on a Reba RL (2017) to 100mm? Are there any new parts I need?

[@marcinhryniszak]

Hello. Yes you need a different air spring piston.

[@controlfreeze9346]

Could you put links to the parts you used?

Hello marcin. I have a sid rlc 100 mm from 2018, or my bike is from 2018, i only have 80mm and 100 mm on the side of my fork, Can i upgrade to 120 mm ? My only corsern is that the front upper legs is to short, do i have Any messure on youres Best regard Robin

[@marcinhryniszak]

Hello. Unfortunatelly I don't have such expirience. I just did this with my fork once. The bike is already with new owner. In your case I would look for answer in the service manual for this fork. I found for my for a nice one with a big table of spare parts (sorry don't remember where). I compared type and year of production and found the proper part that was available. This was a sign that it is possible. So if you can find something like this and find proper part then try. If the change is not possible, at least you will spend some $$ and do a ground maitenence of the fork.

[@Theoneandonlybaconator]

@@marcinhryniszak i did a lower leg and a upper leg service, but it cant, the bushing is sitting to low

[@RobySVK]

Hi there! Can you please measure something for me? What is the length between fork crown and bushing after conversion from 100 mm to 120 mm? I have Reba SL 120 mm and the possible travel is only 100 mm but the length between foro crown and bushing is 120 mm. Thank you for your reply.

[@marcinhryniszak]

Hi. How you measured this? I will check this in my bike.

[@RobySVK]

@@marcinhryniszak tape measure or measure plate. Basically the dimension of the upper stanchions sticking up from the fork lower legs.

[@marcinhryniszak]

@@RobySVK but how did you measure travel, that it is only 100mm.

[@RobySVK]

@@marcinhryniszak let all air out of the fork, compressed to max and felt a hard bottom out, marked the position of the travel with the rubber orange ring and respectivelly put air back to the fork.

[@marcinhryniszak]

@@RobySVK Perfect, that i was thinking. If its real 120mm travel and the fork in standby is on "0" mark, looks like you have to much oil in oil leg. I was servicing one the same fork 100mm and the oil was not enough so the fork was hitting the crown. When i was changing my fork i used a little more oil and the travel (empty air spring) was not full 120mm. I had to remove a little to set correct travel that prevent hitting of the crown an to be 120mm.

[@carlosoleiro3453]

Hi there! Just ordered the parts to increase the travel to 120mm on my Reba. Was not expecting needing to touch on the damper side. Is it really necessary to add oil to the damper? Thanks!

[@marcinhryniszak]

Hi. In my case i was exchanging the oil so i checked the level during exchange. I would check how it works without air (maximum travel and where it stops)

[@Dany-ft3xc]

hello, I did not understand at 8.40, what there is to add or remove. which grease should be used? and what oil for the lower part do you use?

[@marcinhryniszak]

Hello. his is what need to be checked and eventually added. www.bike24.com/p288887.html kzbin.info/www/bejne/a4K3imeciLWZo6M

[@Dany-ft3xc]

@@marcinhryniszak seeing well, the problena is the rod that is in the hydraulic part. With 110mm air shaft, the rod of the hydraulic part is longer, with the 120mm one it becomes shorter and therefore in extension the rod of the hydraulic part reached the end of the stroke.

[@marcinhryniszak]

@@Dany-ft3xc It is working fine for me and i could not seen any problems. Only one thing was to control the amount of the oil in hydraulic part to make a hydraulic stop to not hit to "the ground" when fork was hardly compressed, an in case of problems with air.

[@Dany-ft3xc]

@@marcinhryniszak how quantity 106mm okay? if you happen to measure the entire length of the rebaund rod to check if it is the same length as I have.

[@vittoriobiondi4855]

@@Dany-ft3xc Yes you're right. For this reason I tried to go from 100 to 120mm on my reba 2020 a d bought the 120mm piston. I changed it but, as you told, the fork is not able to reach 120mm because something goes at the end of the run inside and you can ear a metallic beat. I wrote at Rockshox and they told me that on my fork the upgrade 100 to 120mm is not possible

[@gltv1265]

Is this going to work with 2022 SID select+ 110mm?

[@OugaBoogaShockwave]

6:58 😮😮😶😶That's familiar..............🤐🤐 guessing i can do this on my 2017 bike that's 29' also my lockout isn't working

[@RollerbladingwithRoss]

Really new to this, my kona kahuna 2022, comes with 100mm forks, but reading around I can take a spacing out to create a 120mm does this sound correct. If so how do you do it. Like I said very new to this.

[@marcinhryniszak]

Hello. How can i know what fork is installed in your bike?

[@aseppermana3659]

Hi, So it mean, to increase the travel I just need to put more oil?

[@marcinhryniszak]

Hi. Just view the clip once again. Why first I changed the air spring piston to longer one...

[@daniele-nocentini]

which reba do you have converted to 120mm? is possible on sid?

[@marcinhryniszak]

It is Rock Shox Reba RL 26 Solo Air 100 from 2017

[@dariomallamo]

hi...if i would like change from 120 to 100 or 80mm do i have to cut the axle?

[@marcinhryniszak]

Hi. You cannot just cut the axle..there is a thread for bottom screw and the valve. I suggest to buy original part.

[@iancualexandru16]

Hi I have a 30 tk 80mm and I want to upgrade to 100mm can I make the upgrade?

[@fwtadventures6226]

On your Fork Sanctions for travel % Does it say 80mm and 100mm Or 100mm and 120mm Thanks

[@alexiskaravias16]

Hi! This can be done to sid altering from 100 to 120mm travel? Sid sl 29er 2022 model. Thanks for the reply
