    problème bafang mtb Bianchi

    Bonjour à tous, je voudrais vous demander comment monter mon bafang qui touche la fourche arrière. utiliser des cales? ou changer de couronne?

    Google translates to:

    "Hello everyone, I would like to ask you how to mount my bafang that touches the rear fork. use shims? or change crown?"

    I am in the process of putting a bbs02 on a Trek Marlin 5 and had the same issue. I used a hammer to dent the chain-stay a little so the chain ring can clear.

    Google translation: Je suis en train de mettre un bbs02 sur un Trek Marlin 5 et j'ai eu le même problème. J'ai utilisé un marteau pour entailler la chaîne - rester un peu de sorte que l'anneau de la chaîne puisse se dégager.

      Salut, je ne comprends pas, il ne suffit pas de mettre 4mm d'épaisseur?

        Google translates to "Hi, I do not understand, it is not enough to put 4mm thick?"

          The problem you have with chain ring clearance can be solved in a number of ways but search for bafang chain alignment rather than clearance. Your photo seems to show a stock bafang chainring so you have options.


          In summary:

          1. You can push out the bottom bracket by mm using bottom bracket spaces.
          2. You can push out your existing chain ring using specialist chainring spaces.
          3. You can replace your chain ring with one having less offset or a smaller circumference (less teeth). Luna has published an excellent chainring video to explain the options.
          4. As a last resort you may need to panel beat your chain stay.

          Of course if you have to change chainring offset due to chain stay clearance you may cause chain alignment problems which you should aim to reduce. A chain ring with a narrow/wide tooth pattern may be a must rather than being just recommended to reduce chain jumping. I use the 42T Lekkie Bling ring.

            this is the easiest - i just used quarter inch nuts on the inside of the chainring and longer Allen bolts to tighten (BBSHD motor)

              thanks, I do not understand what you mean by '' ring ''

              1. I found adapters on the lunacycle site and others on fasterbikes which one to choose between the two? from 4 mm? :
              https://lunacycle.com/parts/bafang-p...ting-4-pieces/
              https://fasterbikes.eu/it/accessori/...accessori.html

              2. I do not understand what a ring is
              3. what's the link in the chain?
              4. what does it mean to beat the chain?

              can you put examples? sorry but i do not know english use google translator ..

                HI Ste92, Even if you are fluent in English the words "Chain ring" are meaningless unless you are also fluent in bicycle language. I doubt google translator is fluent in bicycle language. :-)

                The "chainring" is the big sprocket at the from that is turned by the pedals. Here is a link to the Lekkie chain ring that I mention. But they call it a "bling ring" because it is "bling" looks great.

                This is a great article which describes both your problem and the options.

                  in the end I put two layers and I resolved everything. the crown I leave the original bafang 44 teeth is fine.
                  now instead I put the engine on my mondraker dune 2016 the engine fits perfectly without problem but I had to cut a piece with flexible and the engine went very well. I attach photos. but now I would like to change the crown because I have 10 speeds on the gearbox and it's too short I thought to buy Lekkie with 36 teeth. the original is 36 teeth of the mondraker so I think it's good. law?

                    Bonjour à tous, j'ai réussi à mettre le moteur que j'avais pour couper ce boulon près du pédalier sinon je ne pouvais pas le monter.
                    mais maintenant je dois changer la couronne avant, le bafang original est 44 aussi.
                    On m'a conseillé de prendre une araignée apposée par 104 BCD pour appliquer la couronne anti-déraillement, ou vaut-il mieux acheter 36 lekkie à 46 € expédiés? Merci
