    2020 BMC Fourstroke 01 Frameset Shock???

    Hi all,

    I just ordered a new BMC Fourstroke 01 frameset to build and replace my 2016 Fourstroke. Iíve looked everywhere and even called BMC USA to no avail on this...what rear shock does the frameset come with? I know it is a Fox DPS Trunion etc, etc, etc...but is it a 2 Pos Remote or 3 Pos Remote? I canít find that answer anywhere!!!!

    Any help on this? I need to buy a fork that matches de shock on Remote Pos...

    Cheers everybody!

    Is there such a thing as a Fox 3 position remote? I thought all their remotes were just open and closed?
    Never underestimate an old man with a mountain bike.

    Did you build this bike from just a frameset? How did you get Rockshox Ultimate for 3 Pos? Scott custom damper? I ask this because Iím really interested in a Rockshox SID Ultimate instead of a Fox Float. Plus, I already have that same DT Swiss lever brand new in a box...

    Thanks for your response!!!

    My bike was assembled and used from a bike shop owner. I got it used.
    Stock rear shock and a tuned Sid ( at the shop there is a special unit for fork tuning ).

    BMC Switzerland must be able to help you. This is the data for my FOX Shock that came with the black frameset: 2019 DPS Float Trunnion 185x50mm, F-S, K, Remote Up, Evol LV, PTL, 0.8 Spacer, 20x8mm hardware. Important to remember it is push-to-lock so the fork must also be push-to-lock. Shock is 3-position, works great with 2-position fork. Stock air volume spacer in shock is 0.8. Recommend trying smaller spacer to get a bit less progressive feel. At 79kg I am using 0.4. I am also using the Scott Twin Lock with integrated dropper remote. Works great

    This helps...

    How come bike manufacturers sell you a frame with a 3 Pos Remote shock and nowadays almost all forks are 2 Pos Remote? This baffles me. My new frame arrives in two weeks and the only thing not ordered yet is the fork...

    I too considered going for 2-position push-to-unlock(PTU) front and rear but the frame really benefits having the middle/trail position. I found the middle position on the fork pointless. In a 3-pos system the 2-pos fork will be open in middle pos. Perfect for me. 2019/20 fork is also easier/cheaper to rebuild from PTU to PTL than rear shock. I believe reason for FOX going for PTU is less trouble with wire and spring returning. There is a bit of maintenance to keep PTL running smooth. Unfortunately no PTU 3-pos system is available yet.

    In the past Fourstrokes that I have owned (3), my best riding/felling has always been on the Mid setting of a 3 Position fork/shock. I've never had a 2 Position fork/shock.

    Hi all, waiting on a Fourstroke in the mail and will be building it up custom from the ground up! I'm thinking about putting a 2 position shock and fork on, in order to put on a Rockshock twist lockout to clear out the amount of levers on the handlebars. A few of you said that the bike rides best in the middle position, coming from a hard tail world, I don't have to much understanding on rear suspension set up. But can't I just get a 2 position shock, pump up a bit more air than specified to match the stock middle position setting?

    I guess the solution with 2 position shock would be to experiment more with compression and rebound that suits youíre riding style and weight. You may have to do some custome tuning with shim stack and so on to sort that out. I have replaced the 0.8 token with a 0.4 in the rear for more air volume and less progressiveness. Air pressure should be somewhere close to what gives you proper sag and make use of the travel the frame can offer. Interesting idea would be to try the new SID Ultimate fork reduced to 110mm travel an the the SID Lux rear shock. If you do, please let us know how it goes.

    Was gonna give ya'll a "long term" review, have put over 1k miles on the bike, and it rides great. I have a handful of criticisms towards the engineering team, will post a review up later. But for now I have to get in touch with the BMC warranty team for the second time. My frame developed a hairline crack on the chain stay, just noticed it today, so am going to be pulling the bike apart.
