    defraz, nice attention to detail!
    Chain looks a bit short; does the frame's linkage have negligible chain growth deep in its travel?

    Hi J. Random Psycho, good point.
    In the meantime i changed the chain with a KMC X9 black color and better regulated the derailleur. I took a photo also on the bigger cog but the phone strangely refused to shhot it and gave a black pictures, Android magic i guess.

    However, zee derailleur can clear a 11-40 with a chain growth less than 2-3 cm (i'm trying to recap based on my memory, i've data somewhere). I checked woth linkage software the frame and should be within the limit. I managed to cut the new chain as long as possibile without losing tension in order to minimize the problem.

    Obviously you are not supposed to arrive full back excursion while being on 30-40, but it should work. I choosed zee derailleur and 11-40 for this reason, to have the derailleur as short as possible while allowing a good range.

    And 9 speed because... well all my bike have 9 speed transmission, but the singlespeed, i started like that and don't want slimmer chain and mud clearance... and i'm a bit of a traditionalist i suppose

    9 speed with SRAM cable pull is a very nice thing indeed.

    I can imagine a situation where suspension might bottom out in the lowest gear: a crazy high drop off to flat that you start from trackstanding at a ledge and doing a pedal-up to raise the front while taking the bike off the ledge.
