Hi everyone, as above really. I’m swapping out an SM-BTR2 that has a plastic/rubber FSA seatpost holder. I’ve removed the battery from the seatpost & disconnected it but I can’t get this holder off. It appears to be one piece, not like the Richley one that is 2 pieces clamped together. Any tricks for getting them off?

    From what I remember the FSA holder has a circlip which needs to be removed to allow the battery to slide out.

    Thanks, from my googling I don’t think it’s that type. It’s just a cheap plasticy 1 piece thing https://www.tredz.co.uk/.FSA-Seatpost-D ... 106659.htm Looks just like this. I can’t find anything anywhere about how you get them off. To fit it appears the battery just slides in :?:

    Probably just a bit of moisture got in there causing it to bind a bit (unless someone decided to glue it in). Try playing a hair dryer over it to soften the plastic and pushing it out with a dowel. A small screwdriver held in a vice (blade end in vice) and the handle used as a dowel to push against, then you can use both hands to manipulate the object. Works quite well for jobs like this.
