    when I searched I did not come across the Shimano documentation, but I wasn't looking for it either as the manufacturer of my crankset isn't Shimano. But as I've seen you mention quite a lot there is a ton of available doc by Shimano so should have thouht about it!

    I'll try the thin grease film then, thanks too!

    That was my thought. Many thanks!

    Thanks, that is interesting.

    I contacted the crankset manufacturer directly that handed me a document where it states "left arm (shim) 12 to 15Nm", I suspected it was for hollow BB and not square for the mention of left arm only and much lower torque compared to what I came across from Parktool or other sources (which seem similar to what you posted, around 35 Nm), but when I raised the interrogation on is it really 12 to 15 Nm, manufacturer did not answer back.
    35 Nm seem to be a value that is recommended on several places so I guess this will have to do...!
    thank you for the help

    I am not sure I understand the answer, so maybe I did not formulate correctly but if anyone have an an idea of the recommended torque for the M8 bolts to install a crankset on a square taper BB, could they tell what is the recommended value?

    Did not seem to have an answer on another thread so trying my luck here:
    Does anyone have an idea of the recommended torque to install a crankset on a square taper BB?
    Install it by feel usually but seem to have overtorqued the last one as crank arm is more engaged on one side so after a reference value for next installation.

    What is the usual torque recommended to install a crankset on a square taper BB?
    Came across 35 to 45 Nm from parktool spreadsheet, 35 Nm from Probikeshop recommendation, and some sources also for around 35 Nm.

    Contacted the manufacturer directly that handed me a document where it states "left arm (shim) 12 to 15Nm", suspected it was for hollow BB and not square for the mention of left arm only and much lower torque compared to what I came across, but when I raised the interrogation they did not answer back.

    So anyone got a usual torque recommendation for these? And please do not describe how you install it by feel, I am after a reference value because I am already doing it by feel but would like to install the next one properly as much as possible.

    Anyone with technical advices such as @gbj_tester for example :)?

    might not be the best place to ask, but thought it was the thread that have the best visibility for this.
    I am trying to think about a potential modification of an existing geometry.

    • frame 1 is head tube angle 75°, fork rake 45mm => trail 42mm and chainstay length + front distance =935mm
    • frame 2 is head tube angle 73.5°, fork rake 54mm => trail 42mm and chainstay length + front distance=960mm

    First proposition will be more compact (smaller wheelbase), but second will avoid much more toe overlap, but overall handling will feel the same because trail is identical, or am I completely wrong?
    or is there any other element than trail to take into consideration for the bike handling and behavior?

    calling the geometry experts and frame builders of the forum!

    nothing matches when it is clean and close one to another on the workshop table but once assembled and ridden I am sure this won't be noticeable and will look cool nonetheless! stunning build

    fork is inspired directly from here but sure is cool :)!

    @_nico nice one!
